Nix was built to help me overcome my own nail picking habit and I hope it will help with yours.

What’s New

Version 2020.3


- Now you can track more than one habit with Nix. Previously Nix only supported tracking one goal at a time.
- Name your habit!
- New habit timeline so you can scroll back to view your habit over time. The old paging UI was undiscoverable and buggy.
- Delete a habit and all associated entries and photos data.
- Select any goal count from 0 - 500 instead of increments of 5.
- Display app store rating prompt less often.
- Remove gif and milestone suggestions on homescreen because they got in the way too much.

Bug fixes:

- Bug where sometimes the annual subscription would not give access to all features.
- Bug where crashes would occur if creating too many entries too fast.

Tracking improvements

I’ve been teaching myself how to make cappuccinos lately, and used this app to track my progress. It’s incredibly satisfying to see the progress side-by-side with a camera log over time.

Looking forward to the day I can call my work true “Latte Art”. Thank you for making my progress so easy to track!

I didn’t have high hopes for such a simple little app, but it worked for me! I’ve been picking or biting my nails for 40 years. I was really motivated to quit this time and this app was just a little extra push I needed to keep me motivated and accountable! I haven’t bitten or picked up my nails in over six weeks now. Thank you!
