I don't even know how the app has such a low grade. There is nothing to compare it to, it always works and has everything you need to use the watch regularly. So what are the low stars for? Are you just 😡 😤😡😤😡😤😡😤😡😤😡😤😡

This app needs a serious fix. Can't see the watch faces to download. Open up this app so the phone can shine.

The SK40 watch is good, but RDFit is disappointing. The app feels outdated, lacks a modern interface, and still has no proper user account system for saving and syncing data. The hardware has potential, but the software experience does not match it. A complete UI redesign, user accounts, and more frequent updates are needed. Please improve this app.

Using the QR code with the watch, keeps disconnecting and saying not compatible with this device ???
