Clear Days is a simple, cute counter for the things you quit. Add a card for anything you're leaving behind: weed, alcohol, cigs, vaping, sugar, caffeine, doomscrolling, whatever it is for you. Type what you quit and the app handles the rest. Each card shows how many days you've been free, the years, months, and days, and a clock that keeps ticking. WHAT YOU GET - Big, clear day counts you'll actually want to show off - Share any card as a pretty image for your story or a friend - As many cards as you want, each with its own icon and color - Milestone alerts at 1 day, 1 week, 30 days, 100 days, every year, and plenty in between - A little progress line showing your next milestone - Start over anytime and your best run is saved, because those days still count - Light and dark mode, or let it follow your phone - Works with larger text and VoiceOver - Works offline PRIVATE BY DESIGN No account, no ads, no tracking. Your cards live on your phone and in your own iCloud, so they come with you to a new phone. Nobody else sees them, including me. A NOTE FROM ME I made Clear Days for myself. I was using two different apps to track quitting weed and quitting drinking, and I wanted one place that felt calm and looked like me. When I shared my screenshots, people kept asking where to get it. So here it is. Clear Days is a personal tracker and isn't medical advice. If you're having a hard time, SAMHSA's free, confidential National Helpline is open 24/7 at 1-800-662-4357. You can also find it anytime by tapping the i in the app.
