The original app had a lot of bugs. In fact, one of the instructions in SRAMAXS was “if you can’t connect to your SRAM, force-quit SRAMAXS , cycle Bluetooth off and on, and reopen SRAMAXS ”. Ha, no lie. Anyway, it works a lot better now. I am able to connect every time I open SRAMAXS now. I was able to change the shifting option from one gear per click to include 3 gears for holding the shifter. I like that you can do that for only 1 direction if you want. My only complaint is the battery level display on SRAMAXS should be bigger, and include percentage. Even nice to have a separate battery indicator app, because once you setup the shifting, you will rarely need SRAMAXS for anything except to check battery level.
I’m happy with SRAMAXS , and I absolutely love my SRAM Eagle system and will never go back to shift cables.
