Installed this app it worked great for a week and stopped working. Now I can't uninstall it. I thought I would try adding it again but it will not let me uninstall. Just a pain
Won't work and can't uninstall
Stopped working and can't uninstall
It worked well for a few weeks then stopped. I open the app, but it won't start. And now it won't let me uninstall!
Worked great for the first workout then it stopped working. Won't calibrate. Tried to uninstall and reinstall, now it won't install. Garbage
Its crap! Can't uninstall
OK so far - needs voice prompts added. Phone app has voice prompts, but the GWA2 only vibrates and tones. No options for voice prompts. Seems to work okay otherwise.
I love it on my phone was excited to add to my watch. Used it 2 times now it won't work and I can't Uninstall to try again:(
It worked on my phone but doesn't move out of calibrating mode on my watch. I'm sad I have to switch apps to use on my watch. Luckily I was able to uninstall the app.
The watch app quite working and I can't uninstall in now. Stuck with an unusable app.
App has been stuck in calibrate mode for days. Cant even uninstall even though it's not usable.
I WAS ABLE TO USE ONCE AND NOW IT WON'T DO ANYTHING. Won't even let me uninstall to see if I can get it back working 🤔🤔😠 disappointed
Used to be fine. Now it's unusable--crashes every time it is calibrating and won't let me uninstall.
Why not just add actual voice cues
