I've just started using this app, which sends reminders to check on on whether I'm clenching my teeth, and what my pain levels are. When I first set the reminder, it didn't work. The second time, it sent a reminder to my lock screen -- but there's no info on how/where to record clenching/pain levels. (Exploration revealed that this is done under "research" in the drop down menu.) The app is a great idea; labels that are more clear will make if even better. Also, it would be great if there were a diary section that allows notes each day. I made a spreadsheet to track how my teeth fit together at different times of the day. It's all related, and I'll try ANY THING to reduce the pain & discomfort I'm I. I'll revisit this review after using the app for a bit.
