Open-sourced fitness bracelet
Recently I've got a fitness bracelet(Honor) to track my sleep better and other metrics. I had an idea to collect as much data as I may through API, so I'd build an app to get my(!) data and analyze it in a way I prefer. Why? I'd like to have data for the years I wear the device to make my conclusions and visualizations, rather than just what I see on their app.

Why would anyone care? A bracelet app may show you how well you sleep, but not raw data you or other people would analyze better. You may scan the data through more advanced algorithms(e.g. employing ML) than just doing "if sleepTime < 6 hours { return 'You slept too little' }". There are good data though my bracelet app presents to me I could handle it to make some other aggregations.

The other thing to mention is it'd be nice to have all your raw personal data that the device collects, right? Why can't you upload it all and analyze yourself? Yes, I bought the thing, give me the great API. Instead, there are many obstacles. In my case, I should register in some Huawei(the Honor parent) company development program, then get their development kit available only on Windows. It's ridiculous.

A potential solution? Well, some (nerd?) human-oriented devices and open API to do what you want with your data. Analyze it. Make your server the device will send the data to. Do whatever you want. No closed APIs and unknown policies regarding your data that is being sent to some big company servers, so they can "improve our metrics".
