2 or more people together on a goal...🥊

Hey folks!

First post here but long-time lurker in this great community!

I have 2 friends that are on a goal to lose some weight. Every week they have a different challenge to accomplish the main goal (i.e: this week they don't eat sugar/ next week they need to go every day to the gym, etc...).

What about an app where they can:

• Share the same goal
• Keep track of their progress
• See each other's progress
• Keep a conversation regarding their goal
• Receive notifications when the other people completed their goal/ remainders to complete the goal.

What are your thoughts on it? 😅
