I was a compulsive nail biter for about 20 years. I tried many times to stop, but I was never able to make it stick.
SoloUno changed that.
For the first time, I found a method that made quitting feel manageable rather than like a constant battle of willpower. I used the app consistently, and it actually helped me stop biting my nails.
After struggling with this habit for two decades, that is a pretty remarkable result for me.
If you struggle with nail biting and have tried to quit before without success, I strongly recommend giving SoloUno a serious try.
