Streaks knows its purpose and does the job well. The interface is clean, there are no distractions, even when it asks for a review, it does so in an elegant way. I bought it in a bundle with Streaks Workout, which I absolutely adore. This is just very good, so if you seem to like it, at least take a look at the other app. Some notes on whats offered. You can choose up to six actions to track, every one can be attached to certain days. So I can track chess practice on fridays and wednesdays, and bodyweight workouts every day except Sunday. You only have to type the name of the activity, and the app tries to guess the icon for you. As soon as I have written Chess practice, a chess piece icon was attached. This is a good example of the attention to detail shown here. All in all, a very good app. I will follow further offerings from this developer.
