Disclosure: Kalend is ours, and it is listed first. It gets the same four fields as every other app, including its drawbacks.
Short answer
Our pick is Kalend — unlimited habits with grace days, next to your tasks and journal, free. If you want a habit-only app you pay for once, Streaks.
Habitify is a polished habit tracker on iPhone, iPad, Mac and Apple Watch. Its listing says it is free on all platforms, with Plus and Pro adding Apple Health integrations, advanced timers and more.
Habit trackers live or die on one thing: do you still open them in week three? This guide compares what each free tier lets you track, and what happens when you miss a day.
Switch to Kalend if
- You track more habits than a free tier allows
- You want habits next to your tasks
- You don’t want a subscription for a checklist
Stay with Habitify if
- You use Habitify on your Mac and Watch
- You rely on its Apple Health automations
- You log habits with an AI assistant

What happens when you miss a day
Streaks break, and broken streaks are why most people quit a habit app. Kalend has grace days, so one miss never resets a streak, and habits can run every day, on chosen weekdays, a few times a week or every few days.
Whatever you choose, pick an app whose free tier holds every habit you actually have. Four is not many.
