Checker is an app that can help you make new habits stick and be more consistent with any goal you're working towards. It uses a calendar/mosaic grid to visualize your progress and help you spot behavior patterns.
I just came across Checker, and I have to say it's really clean, minimalist, yet powerful! The option to track custom units is a game changer for me! I’ve missed that feature in so many other habit trackers I’ve tried. Great job!
