What's the best iOS app for pairing with a cheap health smartwatch from Temu or AliExpress?

FitPro is designed specifically as a companion application for a wide range of budget-friendly, imported health and fitness smartwatches, commonly found on platforms like Temu or AliExpress. Its primary strength lies in straightforward Bluetooth pairing, which reviews indicate is consistently reliable even with generic or lesser-known hardware brands. For users who have purchased an affordable watch to monitor basic vitals, the app serves as a functional dashboard. It visualizes data for heart rate, blood oxygen saturation (SpO2), and blood pressure trends, with options for basic activity tracking like step counting. The interface is simple and focuses on displaying the metrics the connected device can provide.

However, limitations are present. The app's feature set is inherently tied to the capabilities of the connected hardware, and it lacks the deeper analytics, extensive workout modes, or polished ecosystem integration found in apps for major brands like Apple or Fitbit. Some users note minor interface quirks, such as limited customization for watch faces. For its intended use case—pairing with a low-cost device for fundamental health monitoring—FitPro delivers core functionality effectively. It provides a necessary bridge between inexpensive hardware and the iPhone, making basic health data accessible without a significant investment. It is not, however, a substitute for medical-grade monitoring or a comprehensive fitness platform.
