FidMe has Tizen version and works OK on my Gear S3. Pretty simple and straightforward app, works without connected phone after you uploaded the items, but sometimes slow as hell :( Missing the app I used on my Pebble, which was starting and working super fast...

Something like this. I can't remember the name of the one I'm using and I have empty phone...
