Wearable companion apps

A companion app is a mobile app that pairs with a wearable device (smart watch, fitness band, tracker) and works with it in tandem: connection and synchronization, displaying data collected by the device (activity, heart rate, sleep, workouts), push notifications to the device, configuration and control, sometimes its own watch face/mini-app on the watch. Honestly about dependence on the device platform, this is key: the companion works on top of the manufacturer's SDK and rules (Apple Watch, Wear OS, Garmin, Fitbit etc.). What exactly is available (which data, which actions, background operation) is determined by the platform, not us. If the vendor restricted the API, changed the rules or closed access — this directly affects the app, and we cannot bypass the platform's limitations. We honestly work within their bounds. Honestly about 'data is not medical', this is critical: readings from wearable sensors (heart rate, steps, sleep, SpO2, calories) are approximate estimates, not precise medical measurements. They are useful for general trends and motivation but have error, depend on wearing and conditions, and are NOT a diagnosis. This is not a replacement for a doctor, lab tests or certified medical devices. Passing wearable data off as medical accuracy is dishonest and dangerous; we honestly state this in the app. Honestly about health data privacy: the companion works with sensitive personal data (health, activity, location). This requires honest handling: what data is collected, where it is stored, who has access, user consent, compliance. We design this responsibly rather than 'collect everything just in case'. Honestly about battery and background: constant connectivity, synchronization and background operation are limited by the device's battery and OS rules (especially strict for background processes and power saving). 100% continuous background operation and instant synchronization do not exist — the app must be designed accounting for these limitations. Honestly about the effect: we give a convenient companion app within the device platform's capabilities, with honest treatment of data accuracy, privacy and background limitations. Honestly about access: a supported device/platform with an accessible SDK is needed. An important boundary: this is a wearable companion; device integration — 1092; voice assistants — 1096; IoT dashboard — 1091. The base price starts from 100,000 ₽ (depends on devices and features).

• A wearable device needs a companion app (synchronization, data, control).
• Device data is not displayed conveniently on the phone.
• An expectation of medical accuracy from wearable sensors (it is not).
• Manufacturer SDK limitations, privacy and OS background operation are not accounted for.

• Companion app development (pairing, synchronization, data, notifications, control)
• Working within the device platform's SDK and rules (with honest limitations)
• Honest display of data accuracy (approximate, NOT medical)
• Responsible handling of health data (collection, storage, access, consent)
• Accounting for battery and OS background limitations
• Honest boundaries (dependence on the platform/SDK; data is not medical; privacy; background/sync limited)
• Documentation and handover
• Review with you

• A companion app within the device platform's capabilities
• Convenient data display and control with honest accuracy disclaimers
• An honest assessment: wearable data is estimates, not a medical diagnosis
• Honest boundaries (dependence on the vendor's SDK; health privacy; background/battery limitations)

• We assess the device, platform and available SDK (what can really be done)
• We develop the companion with honest data accuracy and responsible privacy
• We account for background/battery, honestly set boundaries and hand over to you

• Is heart-rate/sleep data from the app medical accuracy?

  No, honestly and importantly: readings from wearable sensors (heart rate, steps, sleep, SpO2, calories) are approximate estimates, not precise medical measurements. They are useful for trends and motivation but have error, depend on wearing and conditions, and are NOT a diagnosis. This is not a replacement for a doctor, tests or certified devices. Passing wearable data off as medical accuracy is dangerous — we honestly state this in the app.

• Can you make any feature for smart watches?

  Only within the platform, honestly: the companion works on top of the manufacturer's SDK and rules (Apple Watch, Wear OS, Garmin etc.). What is available (data, actions, background operation) is determined by the platform, not us. If the vendor restricted the API or changed the rules — this directly affects the app, and the platform's limitations cannot be bypassed. We honestly work within their bounds and say in advance what can and cannot really be done.

• Will the app constantly sync in the background?

  With limitations, honestly: constant connectivity, synchronization and background operation are limited by the device's battery and OS rules (especially strict for background processes and power saving). 100% continuous background and instant sync do not exist. We design the app to work reasonably within these limits, but honestly warn: the OS and device do not guarantee uninterrupted background.
