VeryFit
Overview
The VeryFit application, distributed by Shenzhen Aidou Technology, serves as a centralized telemetry management hub and software bridge for an extensive array of OEM and ODM smartwatches and fitness bands, notably the VeryFit Sport, Pro, and IDW wristwear series. Unlike standalone mobile wellness software that relies exclusively on internal mobile device sensors, VeryFit functions strictly as a hardware companion middleware layer. All biometric data capture, motion analysis, and ambient health monitoring depend entirely on continuous or periodic Bluetooth Low Energy (BLE) synchronization with an attached wrist-worn hardware device.
VeryFit ingests raw sensor metrics from paired wearables and transforms them into actionable wellness indicators. Photoplethysmography (PPG) optical sensors located on compatible wearables supply continuous heart rate readings, maintaining an operational accuracy within ±5 beats per minute (BPM) compared to medical-grade chest strap monitors during steady-state physical activities like walking and stationary cycling. The application computes Heart Rate Variability (HRV) from these pulse intervals to establish normalized stress scores, presenting users with continuous stress indices designed for general lifestyle awareness. Sleep tracking features combine tri-axial accelerometer data with HRV signals to construct sleep architecture charts, segmenting nightly rest into light sleep, deep sleep, and Rapid Eye Movement (REM) stages. On equipped hardware models, the app displays spot-check blood oxygen saturation (SpO₂) readings—accurate within ±2% compared to clinical fingertip pulse oximeters under static conditions—and logs estimated systolic and diastolic blood pressure metrics.
Beyond baseline health logging, VeryFit incorporates voice assistant extensions and telecommunications bridging features. Through cloud-routed Amazon Alexa integration, voice queries captured by the smartwatch microphone are routed through the smartphone’s data connection, enabling smart home control, weather inquiries, and task management directly from the wrist. For hardware equipped with onboard speakers and microphones, the app utilizes the Hands-Free Profile (HFP 1.7+) over Bluetooth to support wrists-free calling. Personalization options include a watch face kaleidoscope tool that allows users to convert personal photographs into custom graphical watch dials.
Despite its broad feature set, the application's stability is closely tied to Android OS background permission settings. On devices running Android 12 or newer, background Bluetooth scanning requires location permissions. Restricting VeryFit’s location access to "While using the app" frequently causes background pairing drops, triggering persistent "Device not connected" state errors. Furthermore, Shenzhen Aidou Technology maintains two separate applications in the Google Play ecosystem—VeryFit and VeryFit Ultra—which can create setup confusion during initial hardware onboarding if the incorrect companion app is selected.

FAQs
Does VeryFit track steps and activities if I do not own a smart wristband?
No. The application relies entirely on paired wearable hardware sensors to collect activity, heart rate, and sleep metrics. It cannot track steps through phone internal accelerometers independently.
How do I set or adjust the time displayed on my VeryFit wearable device?
Time settings cannot be adjusted manually on the smartwatch itself. The hardware automatically synchronizes its clock, date, and time zone with your smartphone once a successful Bluetooth pairing connection is established in the app.
Why does the app show "Device not connected" even when my phone's Bluetooth is enabled?
On Android 12 or newer, background Bluetooth scanning requires location permissions. Navigating to Android Settings - Apps - VeryFit - Permissions - Location and selecting "Allow all the time" resolves background disconnection issues.
What is the functional difference between VeryFit and VeryFit Ultra?
The two apps serve distinct smartwatch hardware product lines produced by the manufacturer. Package com.watch.life is designed for VeryFit Sport, Pro, and IDW-series watches, whereas VeryFit Ultra supports separate device lines.
Are the blood pressure and SpO₂ readings in VeryFit approved for clinical diagnostics?
No. All physiological metrics displayed within VeryFit are intended strictly for general fitness tracking, wellness awareness, and lifestyle logging, and are not designed for medical diagnosis or clinical use.
Hot Reviews
Summarized from Google Play reviews and community discussions.
The app provides detailed daily activity summaries, capturing steps, active workout durations, and heart rate trends effectively. The customizable high heart rate notifications offer clear visibility during intensive exercise sessions.
The visual breakdown of light sleep, deep sleep, and REM phases offers a clear representation of nightly rest patterns. Viewing longitudinal sleep data encourages healthier personal sleep hygiene habits over time.
Users frequently experience connection drops where the app reports the watch as disconnected despite active phone Bluetooth. Resolving this requires manually adjusting location permissions to remain active constantly in the background.
The inclusion of the kaleidoscope watch face generator allows for creative visual personalization. Users can transform personal photographs into abstract dial graphics seamlessly.
