Crashes

✨Updated review✨

Thank you for fixing the crashes. App is working wonderfully and is helping me remember to unclench my jaw! I am also able to log tension with no crashes!

✨original review✨

It worked well for a few days and then started to crash where I had to completely delete the app and lost any logged data.

Maybe it won’t do that to you but this was my experience. I would try it again if this was fixed.
