Yes / No is a radically simple habit tracker designed for people who feel overwhelmed by traditional habit apps. No streaks, no charts, no badges, no social pressure. Just a clear question and a single tap. Each day, you answer one thing for each habit: Yes or No. That’s it. Why Yes / No? Most habit trackers try to motivate you with numbers, achievements, and endless analytics. Yes / No does the opposite. It removes everything that creates anxiety or friction and leaves only what matters: recording reality. Features • One-tap daily tracking: Yes or No • Support for multiple habits (up to 5) • Clean, distraction-free interface • Simple calendar view with color blocks • Edit past days anytime • Optional daily reminder • All data stored locally on your device • No account. No ads. No tracking. Designed for calm Yes / No doesn’t try to push you. It doesn’t judge you. It simply remembers what you did. If you want a habit tracker that stays out of your way, this is it. ## CheckOnce Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/08/02/33/080233ea-b5af-6849-6a05-6c74154da122/image.png/1290x2796.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/0e/7a/9f/0e7a9f36-4005-feb3-373c-1c8c5cce7354/Apple_iPhone_14_Pro_Max_Screenshot_1.png/1290x2796.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/6d/72/db/6d72db1f-59f7-b329-8c67-16c611540cc6/Apple_iPhone_14_Pro_Max_Screenshot_3.png/1290x2796.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/b0/df/2b/b0df2bda-1bd7-bca3-9908-455b3ad8caf5/Apple_iPhone_14_Pro_Max_Screenshot_2.png/1290x2796.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f6/63/a2/f663a2ee-9d42-3eb5-69cf-d32540d4c5b2/Apple_iPhone_14_Pro_Max_Screenshot_4.png/1290x2796.png) ## CheckOnce Available In - [Armenia](https://apptail.io/app/checkonce-yes-or-no-Cvyy/armenia) - [Brazil](https://apptail.io/app/checkonce-yes-or-no-Cvyy/brazil) - [Czechia](https://apptail.io/app/checkonce-yes-or-no-Cvyy/czechia) - [Germany](https://apptail.io/app/checkonce-yes-or-no-Cvyy/germany) - [Egypt](https://apptail.io/app/checkonce-yes-or-no-Cvyy/egypt) - [Honduras](https://apptail.io/app/checkonce-yes-or-no-Cvyy/honduras) - [India](https://apptail.io/app/checkonce-yes-or-no-Cvyy/india) - [Jamaica](https://apptail.io/app/checkonce-yes-or-no-Cvyy/jamaica) - [Japan](https://apptail.io/app/checkonce-yes-or-no-Cvyy/japan) - [Kenya](https://apptail.io/app/checkonce-yes-or-no-Cvyy/kenya) - [South Korea](https://apptail.io/app/checkonce-yes-or-no-Cvyy/south-korea) - [Cayman Islands](https://apptail.io/app/checkonce-yes-or-no-Cvyy/cayman-islands) - [Luxembourg](https://apptail.io/app/checkonce-yes-or-no-Cvyy/luxembourg) - [North Macedonia](https://apptail.io/app/checkonce-yes-or-no-Cvyy/north-macedonia) - [Macao SAR China](https://apptail.io/app/checkonce-yes-or-no-Cvyy/macau) - [Panama](https://apptail.io/app/checkonce-yes-or-no-Cvyy/panama) - [Qatar](https://apptail.io/app/checkonce-yes-or-no-Cvyy/qatar) - [Senegal](https://apptail.io/app/checkonce-yes-or-no-Cvyy/senegal) - [Tunisia](https://apptail.io/app/checkonce-yes-or-no-Cvyy/tunisia) - [Uruguay](https://apptail.io/app/checkonce-yes-or-no-Cvyy/uruguay) - [South Africa](https://apptail.io/app/checkonce-yes-or-no-Cvyy/south-africa) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
