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. 🩷

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.

Ghe ability to take photos is good to get involved in the process. Notifications are good but after about a month I started to ignore them. So would like a quick way to take a photo perhaps directly by pressing a button in the notification area, or customize notifications so they are e.g. red color so I notice them.
