Could you build this?
Partial The Android app UI and data storage are standard, but syncing with a Huawei watch depends on a proprietary Bluetooth protocol and encryption that must be reverse engineered.
What it would actually take: The stack is a standard Android app (Kotlin, BLE, local database) plus a protocol layer. The hard part is decoding Huawei's pairing, authentication, and health-data message formats, which needs BLE sniffing and reverse engineering, using open projects like Gadgetbridge as reference. It works only on tested watch models, so hardware access is needed.
