Gadgetbridge - Unofficial APK for Android

Gadgetbridge is a useful tool that lets you synchronize alerts, reminders, and other data in your device with your wearable gadgets. These wireless data transfers of information make it easier for you to back-up your data to an external storage quickly and easily. You will also be able to check and manage your programs and other software installed on your device through your smart gadgets. Gadgetbridge does not require you to create an account, which is a great way of preventing any of your personal information from leaking to public servers. This also prevents developers and vendors from seeing any of your private data.

Gadgetbridge offers fast data transfers, automatically backs up your files to external storage, syncs important reminders and alerts, and lets you track your devices and gadgets. However, it has an outdated interface and lacks features such as a task or file manager and the ability to connect to a cloud storage service.
