fitface-studio

FitFace Studio is an Android application designed for customizing Fit3 (SM-R390) watch faces by allowing users to browse, edit, and install them directly to their watches via Bluetooth. The tool features a catalogue for searching and sorting watch faces, a layout editor for altering backgrounds and widgets, and does not redistribute watch face packages; instead, it edits the original binary directly. With functionalities such as widget movement, color adjustments, and real-time validation before installation, it facilitates a user-friendly interface for personalizing watch faces without the need for app re-signing or installation on the device.
