I have bitten my nails as long as I can remember and after spending loads of money on Acrylics etc to try and break the habit I’ve always gone back to biting. Six weeks ago I came across this app by chance and it’s the best fiver I’ve spent! I listened every night for a week and I’ve not bitten my nails once. I don’t hide my hands anymore and I now actually have long nails that I can paint and even file. Can’t recommend it enough, just download it, you won’t regret it
