- Kalend is the top pick: a free habit tracker that sits beside your to-dos, calendar and journal.
- TickTick is the pick on Android or Windows, with habits and a focus timer in the free plan.
- Gentler Streak, Duolingo and one sec each build one habit: moving, a language or less scrolling.
Most habits don't fail on day one. They fail on the day you forget to check, because the tracker lives in yet another app. The best habit tracker app is the one already open when you plan your day, with progress that nudges rather than nags and a price that doesn't creep up on you.

8.6Some habits need subtracting. You pick up your phone to check the time and land in a feed again. one sec steps in before the app opens, asks you to take a breath, then asks whether you really want to continue. That pause is often enough to break the habit.
More about one sec
Stats on attempted opens show whether the urge is fading, and strict or scheduled blocks back up the pause when it isn't. The catch: the free version covers only one app, and the gentle pause is easy to tap through.

How to choose
What makes the best habit tracker app?
It should be quicker to tick a habit than to skip it. Look for widgets or a watch app, and a view that shows progress over weeks, not just today. Free should mean the habits themselves, not a trial that locks your history later.
Then think about where you already look each morning. A tracker inside your planner, like Kalend or TickTick, gets seen because you open it anyway. A single-habit app works best when the habit happens inside it, like a language lesson.
How many habits should you track at once?
Start with two or three. A long list of daily checkboxes turns into a wall of misses on a busy week, which is a great way to talk yourself out of the whole thing. Add a new habit once the first ones feel automatic. Apps that forgive rest days, like Gentler Streak, make a slip easier to recover from.
Get Kalend if you're on iPhone and want habits tracked right where you plan the day, for free. If your days run on Android or Windows, TickTick tracks habits everywhere you go.
