Glad I moved to Garmin a while back. I preferred Fitbit's Dashboard over Garmin
When I heard Google's buying it, I got a Garmin for my next smartwatch just to check the UI. I was thinking of moving back, but I guess I won't.
Garmin seems to be embracing smartwatches with a number of different series
Basically, gadgetbridge is a third party open-source application that replaces the manufacturer app for a bunch of fitness watches (and other devices of that kind).
So you can use it to replace the phone connectivity functions (like receiving notifications etc) as well as getting visualisations of the data etc. And since it all happens locally, none of your data is stored on the manufacturer's servers. If you understand how to work with SQL and statistics, you can also run your own statistical analyses, since it's just a sqlite DB.
The downside is that you can expect it to be limited in functionality compared to e.g. Garmin's cloud functionality. Personally I find there's enough data to be useful, but other's might have different needs.
Not at exactly the same time since the app and watch communicate over Bluetooth. You should be able to pair and repair between the apps, but I haven't tested it myself.
Gadgetbridge is a free and open source Android application that allows you to pair and manage various gadgets such as smart watches, bands, headphones, and more without the need for the vendor application. So in short, you can use Gadgetbridge instead of relying on your gadget's own proprietary app.
Great to see all the Garmin love, I'll have a look.
Just got an ancient Garmin standalone GPS from the thrift store. Soldered a new battery in and it's GTG. Even with zero updates, the quality is top notch. One example; It's been untouched and turned on in my hiking pack for over a month. Battery is full hot!
