I have something that may interest you. With two of my friends, we created a Naviko app - habit tracker with a social aspect. It gives you possibility not only to track your daily routines but also to share this progress with your friends and follow their everyday score. If you have the same habit, you can also compete with each other by getting the longest strike.

Available on Google Play:
