About this app

Wish you could stop biting your nails?

NailKeeper will motivate you to quit the habit of nail-biting.
I've suffered from this bad habit for a long time. I tried many different things, but nothing helped me more than seeing my nails in photos. NailKeeper will keep track of your nails growth by showing you a photo comparison and video progression of your nails. Easily track your progress and quit nail picking and biting habit.

FEATURES:
- Take photos to track your nails changes over time.
- Check progress with a before and after image.
- View a photo comparison in video mode to see how your nails recover.
- Get notifications to take photos and log your progress.
- Monitor how much time has passed since you quit. Restart the timer if you relapse.
- Learn tips and tactics to grow your nails faster and better control your impulses.

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. 🩷

Update: This app was my favorite, but I'm sorry to say I am installing due to the app now contianing AI, which I dont agree with. 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!

I LOVE this app, I've been biting my nails for over ten years, and in just seven days with this app, I've stopped a habit I never thought would stop. And I'm not sure why, this app is literally so basic. I take photos of my nails each day and compare them to say number one. There's also a stopwatch to show you how long you've gone without biting your nails. 🫶🏼 Def recommend.
