this app, and the watch (sirius hunter) is great. it's my first dive computer, so nothing to compare it to. read the instructions to get the best experience, but the basic functions are pretty intuitive.

Between the app and the bluelink connector, nothing works. Hard to connect. Can't download data without firmware update. The firmware update took 20 minutes to get to 93%, then the bluelink device went flat. Now my computer is stuck in firmware upgrade.

I can use the Mares app the first time I open it. I log in, accept all the permissions it requests, configure it, and connect to the dive computer without any problems. I was even able to update its firmware. When I try to access the app a second time, it doesn't open; it just gets stuck on the Mares logo. If I delete the Mares app data and reinstall it, the same thing happens: I can access it only the first time, and then it won't work again. I've tried the SSI app, and I have the same problem.
