About this app

I don't really rate apps much.. but I've been biting my nails for over 20 years. I've tried everything you can think of to stop this habit, but I would always go back to chomping down on my nails. Back in December I installed this app. I didn't know if just taking pictures of my nails now and then and comparing them was *actually* going to help. Boy was I wrong. It's very motivating to see the changes in your nails and how many days have passed. If you have tried everything too, try this. 🩷

The idea behind this app is simple and smart. However there are plenty of buggy things about it. I've had an issue where a lot of my pictures aren't viewable in either main screen when watching the full "video" or in the media gallery. They're just white. When I took some they also had the orientation messed up, I feel like that's related. I wish you could retake a picture. The one time fee is absolutely worth it. ive used it for 2 months, 7 relapses, but huge improvements so far!

Update: The app has some AI features, that I don't agree with, but they're togglable. Your app is one of the few things that helped me be consistent in stopping biting my nails! being able to track my progress is a nice way to instill a sense of pride and accountability. Also being able to compare before and after photos is nice!

Hi, thanks so much for the feedback, and I’m really glad the app has helped you on your journey. I added the AI feature thinking it could be a helpful addition, but I completely understand it’s not for everyone. I’ll be making it optional in a future update so users can turn it on or off. Thanks again for sharing your thoughts!
