Complete OS › Habit tracker
Habits that show up when you do.
Most habit apps are a checklist with a calendar behind it. Complete OS puts your habits inside the rest of your day — it knows which ones are due, when in your day they belong, and whether your streak is on the line — and tells you at the moment it matters.
Why habit apps quietly stop working
The list gets long, every habit looks equally urgent, and the app pings at 9pm to say you missed six things. Complete OS does the opposite: a morning habit appears in your morning, a weekly one only on the days you set, and the Daily Brief shows the one that needs you now — not the whole list.
Scheduled for the days you mean it
Set a habit for every day, weekdays, weekends, or the exact days you choose. On its off days it moves to a "Not today" list, so today's list holds only what is actually due — and your streak counts the days in a row you check it off.
Surfaced at the right time
Habits live on a card that appears in your Daily Brief when they are due. Morning habits in the morning, evening habits in the evening — and the app anchors "morning" to when you wake, so a night-shift morning at 5pm still works.
One tap, then get on with your day
Check off from the Today page without opening a separate habits screen. The point is to spend less time in the app, not more.
Echo knows your streaks
Ask Echo, the AI assistant, "what am I about to break?" and it answers from your real habit history — it already has the context, so there is nothing to re-explain.
Habits that live with your tasks, calendar, and meals
Because habits sit next to your calendar, tasks, budget, and meal plan in one place, the Daily Brief can weigh them against each other: a busy calendar morning pushes a flexible habit later; a slow evening surfaces the one you have been skipping. A standalone habit app cannot see any of that.
Frequently asked questions
Can I set habits for specific days of the week?
Yes. A habit can run every day, on weekdays, on weekends, or on any set of days you pick. Days it is not scheduled, it waits in a "Not today" list instead of crowding the habits that are due.
What happens to my streak if I miss a day?
The streak counts days in a row, so it starts again from your next check-off. The app does not shame you for it — the next due day simply shows up again in your Daily Brief.
Does it work on iPhone and the web?
Both. There are native apps on the App Store and Google Play, plus a full web app; one account, and your habits and streaks stay in sync across every device.
Does it work if I work nights or rotating shifts?
Yes. Complete OS anchors your day to when you wake up, not to the clock, so a morning habit shows up in your morning even if that morning starts at 5pm. Most habit trackers assume a 9-to-5 day and mark you as missing habits while you sleep.
Can I start New Year habits for 2027 if I work a rotating schedule?
Yes. Set each habit for every day or for the days you pick, and Complete OS anchors your day to when you wake, so a morning habit lands in your morning whether that is 6am or 6pm. Weekday schedules repeat each week, so if your rotation moves around, keep the habit daily or change its days when the rotation changes — it takes a few taps, and the habit and its history stay put.
How much does the habit tracker cost?
Habits are part of one Complete OS plan at $9.99 a month, which also covers tasks, calendar, budget, meals, workouts and Echo. Start with a 14-day free trial; no card is needed to begin.
Do I have to open a separate habits screen every day?
No. Habits that are due appear in your Daily Brief on the Today page, and you check them off there in one tap. The habits screen is for setting them up and seeing your streak history.
Download Complete OS on the App Store, get it on Google Play, or use the full web app. One plan, everything included, 14-day free trial, no card required.
