Most habit trackers punish you for the days you miss. Ever Better does the opposite. Every day is a clean slate with a real shot at 100%, so you're always moving forward. Track the actions that improve your life across Mind, Body, and Spirit, and get credit for the effort you actually put in. It didn't start as an app. Nearly two decades ago, one of our founders read Benjamin Franklin's "Plan for Moral Perfection" and began scoring daily actions in a spreadsheet. Eighteen years and countless revisions later, after no habit app got it right, that system became Ever Better. HOW IT WORKS FORWARD-LOOKING SCORING Yesterday is done. Every morning is resets to a fresh 100% opportunity, so one bad day never drags you down, and you never need to wait for a new week, month, or year to begin again. PROPORTIONAL CREDIT Did more or less than your goal? You get exactly the credit you earned. Some is better than none. Partial progress always counts. FLEXIBLE GOALS Track a simple "done," or track by the numbers. Daily, every few days, or a set number of times per period, in your own units. Need a break? Pause anytime without breaking your stride. MIND, BODY & SPIRIT Every action rolls up into three areas of your life, so you can see at a glance whether you're growing in balance or letting one slide. DAILY 100% TARGET Forget perfection forever. Just aim for 100% today. MORE FEATURES SUPPORT GROUPS Invite friends with a code or QR scan, see how everyone's doing, and cheer each other on. Accountability works better together. ACTION PACKS Start faster with ready-made collections of actions you can add, customize, and share. PERSONALIZED HEALTH ACTIONS Connect health data securely and receive personalized action suggestions based on your health profile. SMART REMINDERS Set as many reminders per action as you need, at a specific time, a time of day, or whenever works best. Gentle nudges, not nagging. REVIEW & GET INSPIRED Clear charts, history, and streaks show how far you've come and where to improve. Progress you can actually see. Plus dark mode, and sign in with Apple, Google, Facebook, or email. WHY WE BUILT IT We spent 18 years trying every habit app and always returning to a clunky spreadsheet, because none matched how real change actually works. Ever Better was built to finally replace that spreadsheet, and like the habits it tracks, it keeps getting ever better. We hope you find it as helpful as we have.
