Gadgetbridge, a free and open source project, has existed since 2015 to allow wearable device customers to use their hardware without being tied to the online services of the manufacturers. The small but very focused and capable technical community working on the basic functionalities such as retrieving the various data from the wearables (detected activities, sleep, pulse per minute, peripheral oxygen saturation, ...) lacks the expertise on specialised algorithms that could help to perform advanced analysis/diagnostics. The goal of this talk is to explore a potential collaboration between our communities: Gadgetbridge provides local-only support for an extensive list of wearable devices and a community of engineers and privacy minded users, Data4SmartHealth might contribute advanced algorithms and AI on edge devices.

Bluetooth watches, fitness trackers, so much to pair,
Gadgetbridge, you're the answer, we're well aware,
No more vendor lock-ins, no more corporate strings,
Our data stays private, and freedom it brings.
Gadgetbridge, Gadgetbridge, it's the one we crave,
Open-source magic, gonna pave the way,
Connecting devices, bridging every gap,
A project so sweet, like a midnight snack.
Gimme, gimme, gimme that Gadgetbridge,
I want to sync my gadgets, don't you see my wish?
Gimme, gimme, gimme that open-source dream,
No more locked doors, with this software team.
