We are sleeping worse and resting less and less. But at the same time, we carry it on our wrist and in our pocket. devices capable of measuring Almost everything our body does. The combination of SleepisolBio with Wear OS watches takes advantage of just that: your real sleep and health data to intelligently organize your rest, without you having to go crazy configuring a thousand options.
The underlying idea is simple but powerful: Using circadian rhythm science, artificial intelligence, and targeted sound therapies to help you sleep better, focus when you need to, reduce stress, and get out of bed without feeling like a zombie. All this with a strong focus on privacy and putting your information first, not intrusive banners or pay-per-view screens, including features like... Android sleep time mode.
Sleep management based on your circadian rhythm
Personalized sleep management It revolves around your circadian rhythm, that is, your internal 24-hour clock that dictates when you're most awake, when you get sleepy, and how parameters like body temperature and heart rate fluctuate. Unlike other apps that only count hours of sleep, the key here is understanding when sleep, how you sleep and What's happening to your body? for the whole day.
Analysis of patterns and biorhythms based on data recorded by the mobile phone, by compatible devices and by your Wear OS watchBased on this, it produces a detailed report summarizing sleep phases, possible disturbances such as snoring, and how your circadian rhythm behaves throughout the day, cross-referencing parameters such as heart rate, body temperature, oxygen saturation, or blood pressure when available.
AI-adapted plan Tailored to you. It's not just about telling you "go to bed at 23:00 PM," but about adjusting schedules and recommendations so that your rest is in sync with your actual biology, not a generic timetable. This approach is known as chronotherapy or time-based therapy, and it aims to align your sleep, energy, and peak concentration with your internal clock.
Advanced payment management It is activated through in-app purchases. However, the service's philosophy is that even non-paying users can better understand their sleep patterns and utilize some of the free sleep support tools.
It is not medical softwareIt's not a sleep aid, but a wellness tool. Its aim is to help you sleep better and manage your daily life, not to diagnose illnesses or replace a healthcare professional—something to keep in mind if you suffer from serious sleep disorders.
Recommended sleep schedules and daily therapies
Manage your schedule according to your own pace which is based on your personal circadian rhythm. The app doesn't just record what time you go to bed and wake up: it analyzes how long it takes you to fall asleep, how your sleep stages are distributed, and how that fits with your daytime habits, to suggest sleep windows that are more suitable for your body, aligned with adjustments that help minimize interruptions.
Recommendations for specific times Use it before bed, when you wake up, or even during times of day for sound therapy sessions. The idea is that when your body is most receptive to certain types of stimuli, you receive the therapy that best suits your needs: relaxation, concentration, recovery, or stress reduction.
Therapy categories in four main blocks —Sleep, Focus, Healing and Stress— with a total of 48 sound sessions designed for different states and needs of daily life.
24-hour comprehensive approach It tracks the entire 24-hour cycle, from when you wake up until the following night. The app analyzes your activity and biorhythm throughout the day to recommend, almost with a tap, what type of sound or session can help you at each stage: concentration during work hours, relaxation in the mid-afternoon, stress reduction after a long day, and so on.
Personalized wellness schedule It automatically adapts to your data, preventing you from constantly configuring schedules or manual playlists. You decide whether to follow these recommendations or not, but the foundation is your own biology, not a generic calendar.
High-quality sound and mindfulness therapies
Catalog of free therapies covering everything from sleep to mental productivity. These therapies are organized into four main blocks—Sleep, Focus, Healing, and Stress—with a total of 48 sound sessions designed for different states and needs of daily life.
12 therapies per category These can include relaxing environments, sounds designed to maintain focus, more "healing" soundscapes, or audio intended to relieve accumulated tension. The user can activate them manually or follow the app's suggestions based on the time of day and their physiological state.
Mindfulness content Combining mindfulness practices with specialized audio support. This includes 16 sound tracks focused on meditation or mindful relaxation, as well as a wide repertoire of brainwave tracks designed to induce different mental states, connecting with resources from emotional health.
Brain waves and frequencies16 Theta tracks, geared towards states of deep relaxation and creativity; 24 Alpha tracks, associated with calmness and gentle concentration; 24 Beta tracks, designed for cognitive activation and focus; and 32 Gamma tracks, related to states of high attention and intense mental processing. All this material helps you adjust your mental state to the goal you have at that moment.
High quality audioAll the MP3 tracks included in SleepisolBio are produced in high-quality stereo, with a bitrate of 320 kbps and a sampling rate of 48 kHz. In other words, these aren't basic recordings, but rather resources designed to sound good even with good headphones or speakers, which is appreciated when you spend a lot of time listening to these therapies.
Bedtime stories and real-time generated sounds
Narrative bedtime stories These stories accompany you in the minutes before sleep, with a calm tone and slow rhythm, allowing your mind to gradually release tension as you let yourself be carried away by the narrative. This approach is useful if you are looking for techniques to disconnect and complement a possible digital detox.
Six types of stories For bedtime, you can try different ones until you find the ones that suit you best. This type of content is especially useful for people who find it hard to stop dwelling on things at the end of the day and need a gentle distraction to unwind.
Real-time therapeutic soundThis means that it not only plays pre-recorded tracks, but can also create specific sound patterns depending on the therapy selected.
Monaural, binaural and isochronicThese are three different ways to modulate sound to influence brain activity. Monaural and binaural tones play with frequency differences between both ears to induce certain mental states, while isochronic tones use very defined rhythmic pulses that the brain tends to follow naturally.
Personalized audio first aid kit which allows each user to configure everything from falling asleep earlier, to performing better while studying, or recovering from a particularly intense day without carrying tension into the next day.
Interface focused on your data, not advertising
Ad-free interface It's how it organizes information on screen. Instead of prioritizing ads, subscription screens, or marketing messages, the app puts front and center what the user is really looking for: their sleep data, analyzed and presented clearly. It also takes into account the mobile phone usage limits to avoid overwhelming you with notifications.
Break summary on the main screenWith the data the app has processed about your nights and your circadian rhythm, you can see how you slept as soon as you open it, whether anything stood out, and how it all fits with your habits over the past few days.
Data-centric designWhen you open a sleep app, you want to see how you sleep, not a barrage of banners or "subscribe now" messages. At SleepisolBio, the advanced paid features are there, but they don't obscure or hinder access to the information you're interested in.
Personal expert approachIt aims to become your personal sleep expert, someone who truly understands you. The app wants you to feel that every time you open it, you're getting helpful information and clear recommendations, rather than distractions or content that doesn't contribute to your rest.
Alternative to ad-supported apps where many solutions end up becoming advertising platforms. Here, the priority is that you have your metrics and therapies accessible, and that you can make daily decisions about your sleep with solid information at hand.
Fully customized sleep management system
Rest as a 24-hour cycleFrom the moment your alarm goes off until you go back to bed, this system tracks not only what happens while you sleep, but also what happens while you're awake: your activity levels, your energy peaks and troughs, your physiological parameters, and your exposure to different sound therapies.
Customized management system which automatically adjusts the therapies it suggests to you. If, for example, your circadian rhythm data indicates that you tend to experience an energy dip in the mid-afternoon, it can suggest a gentle focus or recovery session that fits with that specific time.
User-friendly interface for non-expertsBecause the app itself translates the technical data into simple recommendations: what to listen to, when, and for what purpose. This way, with just a few taps, you can activate the therapy best suited to your state and the time of day, without having to understand all the scientific background in detail.
Learning through continued use and from linked devices, so the longer you use it, the more refined the suggestions become. Over the weeks, the system can detect subtle patterns in your sleep or your response to certain therapies, and adjust the sound and schedule accordingly for even greater effectiveness.
Automated wellness routine It accompanies you in your daily life, reducing the effort you have to dedicate to thinking about how and when to rest, and letting you simply follow the recommendations when you want to improve your well-being without complicating things.
Real-time biofeedback: your heart as your guide
Real-time biofeedbackespecially through heart rate analysis. When you're using the app's therapies, compatible sensors—like those in your Wear OS watch—collect your pulse data so the app can adjust the type of stimulation you receive.
Adaptation according to heart rate This allows the therapy to be adapted to your current state, rather than acting solely on historical data. If your heart rate spikes at a given moment because you're very tense or stressed, the app can favor calmer sessions or those focused on reducing that activation, while at other times it can opt for more energizing or focused therapies.
Awareness of bodily responseBecause by seeing your heart rate data before, during, and after sessions, you can get a very clear idea of ​​what types of therapies work best for you. This can help you adjust your own habits, knowing, for example, which sounds really help you wind down before sleep.
The pulse as a guide It makes your body the focus of the experience, not just a passive data generator. This live biometric information is what guides SleepisolBio in offering you the "most suitable" therapy for you at any given moment, fine-tuning recommendations and avoiding a generic approach that might not fit your physiological reality.
Individualized sleep profile and stress response, and that there is no one-size-fits-all solution. The app uses your data and reactions to give you an increasingly precise experience, which is refined over time and with continued use of the therapies.
Smart alarms for a more pleasant wake-up
The Importance of a Good Wake-Up Call It's almost as important as getting a good night's sleep, which is why SleepisolBio pays close attention to the design of its alarms. It's not just about something going off at a specific time, but about the sound and type of alert helping you get out of bed feeling better and more rested.
A varied collection of alarmsWith around 30 different options, you can choose tones other than the typical shrill beeps that put you in a bad mood. The variety of sounds allows you to find something that suits your waking style, from gentler alerts to more energetic tones for those who need a good jolt.
Brainwave-based alarms18 sounds specifically designed to gradually "activate" your brain. These sounds are intended to gently wake you from sleep, moving away from the jarring sensation of traditional alarms and aiming for a gentler awakening.
Themed alarms for special occasions These are dedicated to occasions like Christmas, New Year's, or birthdays, with around 10 different options. They won't completely transform your vacation, but they do add a more personal and fun touch to those special days.
Missions to activate the brain These tasks can help your brain activate more gently when the alarm goes off. They might involve making a hand gesture, solving a simple calculation, or interacting with information about your own sleep, so you don't automatically turn off the alarm and fall back asleep without realizing it.
Missions to activate body and mind upon waking
Mission objectiveIt prevents you from turning off the alarm out of habit and going back to sleep. Instead of a simple "snooze" button, the app suggests small tasks that force your brain and hands to get moving, making waking up more conscious.
Missions with manual gestures that make you move your hand or wrist to complete the task. By having to perform a movement that is somewhat more elaborate than pressing a button, the body begins to emerge from the lethargy of sleep.
Missions with calculationsforcing the brain to activate minimally. They aren't complicated problems, but they are enough to make you pay attention for a few seconds, just enough to break the inertia of continuing to sleep.
Missions with sleep dataThis allows you to interact with what happened during the night. Seeing and managing this data first thing in the morning can help you become aware of how well you slept and whether you need to change anything in your routines from the night before.
A more conscious awakening and something more participatory, which reduces the temptation to close your eyes again and snooze the alarm over and over, one of the biggest enemies of quality rest.
Wear OS integration: your watch as an ally
Integration with Wear OS watches To get the most out of its biofeedback and sleep management capabilities, the watch becomes a constant sensor that records your heart rate and other parameters while you perform the therapies suggested by the app.
Wear OS app coordinated with the mobile phone Designed to work during therapy sessions, this app obtains your pulse data in real time. It's important to note that this watch app is not designed to be used independently, but always in conjunction with the main app installed on your phone.
Richer data with the watch This allows SleepisolBio to receive much richer and more detailed information than can be obtained with just a phone. By being in direct contact with your wrist, the watch monitors your heart more accurately, enabling better adjustments to therapies and a deeper understanding of how your body reacts to each session.
Recommendation: Galaxy Watch and Sleepisol device To access all the most advanced features, you'll need a compatible Wear OS watch, although the core experience can be enjoyed with other Wear OS compatible watches. The important thing is that they have the necessary sensors to accurately measure your heart rate.
Complete monitoring ecosystem With your mobile phone, watch, and Sleepisol device, your sleep and daily activity are recorded in considerable detail. This allows the system of personalized sound therapy recommendations to become more refined and effective.
Connecting to Google Health Connect and using health data
Integration with Google Health ConnectGoogle's platform that aggregates health data from various apps and devices. This connection allows the app to access valuable information to build detailed graphs and analyses of your physical condition throughout the day, and connect with essential Android apps who also handle health data.
Permissions and data requested These include sleep, heart rate, blood pressure, body temperature, oxygen saturation, and steps. With this data, SleepisolBio can generate a circadian rhythm graph that shows how these parameters vary throughout the 24-hour cycle, helping you to clearly visualize your biorhythms.
Daily map of circadian rhythm It functions as a kind of "daily map" of your body, where you can see when your pulse spikes, when your temperature reaches certain peaks, or how your oxygen saturation behaves. This comprehensive view is very useful for detecting imbalances, unhealthy schedules, or the effects of habits such as lack of exercise or eating late dinners.
Use of step data for daily activity To display your daily activity on the main panel, you can always see if you've been active enough or if you're leading a sedentary life. This is important because sleep quality is closely linked to your level of physical activity throughout the day.
Local data processing This is reassuring: all this information is used solely to display graphics within the app and is not stored on external servers or shared with third parties. The data is processed and stored directly on the device where the application is installed, maintaining a fairly strict approach to privacy.
Privacy and local storage of information
Data-intensive usage context While many health and wellness apps make intensive use of personal data, SleepisolBio stands out for its policy of processing all information directly on the user's device. There is no constant sending of logs to a remote server or sharing of data with other companies without your consent.
Data collected by the app Sleep patterns, heart rate, blood pressure, temperature, oxygen saturation, and steps are used exclusively to generate the graphs and dashboards you see within the application. This data is not used for any other purpose and is not uploaded to external servers for commercial use.
Storage and local treatment It takes place on the device where the app is installed, which reinforces the feeling that the data is more under your control. This doesn't eliminate the need to properly protect access to your phone or watch, but it does reduce the risks associated with leaks of large cloud databases.
Focus as an expert in personal sleep that works with you and for you, not a platform whose main objective is to exploit your data. For many privacy-conscious users, this detail can be decisive when choosing a sleep management app.
It does not replace a medical consultation It doesn't prevent you from having to see a professional if you suspect a serious health problem, but it does aim to give you tools to better understand your rest and make more informed decisions about your daily habits.
Combination of technologies and privacyIntegration with Wear OS and Google Health Connect, along with a strong focus on privacy and prioritizing your data, makes SleepisolBio a very complete option for those who want to go beyond the typical sleep tracker and opt for smarter and more personalized management of their health and rest.
