Ratings and Reviews

Best app ever!! For all types of goals!!


It's amazing!! It keeps me motivated and interested!! I am 100% in love how you can add challenges to your profile and how it reminds you and how you can follow others who have same goals as you and invite you to other challenges it's the best app for every area of your life!!

Fun way to get stuff done (and compete with friends)


I love this app! At first, I just wanted to get some personal goals done (eg exercise more, read more, eat healthy). But the moment some friends joined, it was a whole different ballgame. All of a sudden I find myself doing a lot of things I never thought I would (or could), like seeing who can plank the longest, or who can keep the longest water drinking streak, etc. All for bragging rights. It's been fun doing activities / challenges w other people who share the same interest.

The app itself is pretty easy to use, let's you message each other (trash talk), easily join/leave challenges, make your own ones, and so on. Give it a whirl...!

Constructive and fun challenges? I'm in!


I truly like the interaction you get to have with others. Being able to be you and share your excitements with others is such a positive way to build challenges. This app is excellent. Truly recommend it.
