HabitBull's app has a simple but powerful UI where you can see your whole month at a glance. With this UI, it's really easy to see on which day you broke a habit.
Further, their app has graphs and charts showing you visual data on how you performed with your habits, and what your success % is as compared to your desired goals. It's even better that you can export all the data in CSV format and analyse it by yourself all you want.
One really cool feature is the ability to decide how often and how many times you need to perform a habit. It could be that you need to exercise 2 times a week, which HabitBull allows you to track easily.
Momentum is a beautiful and simple habit tracker app built exclusively for Apple devices.
The core principle behind the app's design is based on Jerry Seinfield's productivity secret, which is - Don't break the chain. Each day you lengthen the chain, you make it more likely for you to stick to your habit and therefore less likely to stray from the path.
With an extremely simple and minimal UI, you can you glance all your habits in a second. Thanks to deep iOS and Watch OS embeds, you can check off a habit with one tap from the home screen or notifications shade.
