Everstreak: Habit Streak App

Everstreak is a habit tracker and streak tracker built around the daily streak counter. Track habits you want to build and habits you want to quit, like smoking or drinking: for a habit you quit, each day you did not do it counts. Streaks run by the day, the week or the month.

What sours people on streak apps is usually the way a streak breaks. So here are the rules, written down before you start.

One. Today never breaks a streak.
A day that has not finished is not counted as a failure. You will not be told at 9pm that today is already missing, and grace is never spent on today.

Two. If a habit isn't daily, the days it doesn't need are not scheduled in the first place.
Only a habit set to daily demands every day. Set it to three times a week and the streak holds as long as three land inside the week. Five a week, four a month and every second day work the same way. Weekly and monthly habits are counted in weeks and months, not in days.

Three. You get 0 to 3 grace uses per calendar month.
A missed scheduled day gets filled in automatically. How many you carry is set per habit. Set it to zero and nothing is forgiven.

Four. Work done on an unscheduled day still counts toward the streak.
If you did an every-second-day habit on its off day anyway, that counts as moving forward.

Logging is one tap on the habit. The streak counter moves and the heatmap fills a square a day. Your longest streak and lifetime total are on the Records tab and on each habit's page.

Quit a habit
Everstreak also works as a quit habit tracker, for example to quit smoking or drinking. Set a habit's kind to Quit and a day you didn't do it becomes the achievement: no smoking, no drinking, no late-night snacks. Used that way it is a day streak counter: you tap the habit on each day you held out to keep the streak. It counts days; it does not track money saved or health milestones.

Five milestones: a streak of 7, 30, 100 or 365, and comeback, the first time you start again after a streak ended. The day after a break is exactly when people tend to give up, so it gets a milestone of its own. The list of milestones you have passed is part of Pro.

The start of your day is adjustable, for anyone who wants something done at 2am counted as yesterday. So is the first day of the week.

Free
Up to 5 habits. Entries themselves are never counted against you. Your current habit streak, your longest ever, and your lifetime total are always shown in full, over any span. The board (the heatmap) covers the last 90 days. A single "Your hour" figure. No ads. Removing a habit takes it off the list and frees a slot.

What Pro opens
No limit on habits. The board goes back a year or further. Completion by weekday, a 24-hour distribution of when you log, a per-habit breakdown, and the list of milestones you have passed.

Monthly and yearly subscriptions exist, but the one being pushed is the one-time purchase. Pay once and nothing renews.

Not included
Reminders and notifications. Widgets. In-app export and backup. Cloud sync and accounts. Health app integration. Money saved or time elapsed for quitting. Per-habit rest days and pauses: there is somewhere to store them, but the screen to set them has not been built yet. Runs in English and Japanese.
