Liked the idea! Can I create a bundle of challenges and send it to a friend at once? It could be like a workout routine. Gamification works wonders when it comes to fitness, hope you will continue adding more features, good luck!

So glad to hear! Right now, users can only send one challenge at a time, but yes! You will be able to send and receive combinations of challenges. We are currently working on the multi-challenge feature, and it will be available before the launch. To give you an example, you will be able to send and/or receive push-ups, yoga, meditation all in one day.
