It's very simple in what it does but the simplicity keeps it from having certain features, the biggest of which is a way to mark a habit for prior days.
If you don't remember to check in and say you completed something one day, it resets your streak and won't allow you to edit it. I had a streak going but forgot to check in and now I have to start all over. If the developer could allow you to mark past days, I could give it five stars. As it is, it's only good if you're perfect with checking in which, let's be honest, if we were we wouldn't need this app.
