Habit-forming for kids made easy: Feedback Required.

Hi, IH Parents,

My first post on IH.

I have built an app (dinostar.app) for helping kids build habit-forming routines. I am using the Cue - Action - Reward framework for developing habits.

I want to get feedback on two things:

1. The idea -
1.a. To fully realize the habit-forming loop, we will send the kids a poster with a theme (e.g. forest, or outer-space) which acts as a cue to activities they have to do to earn a reward.
1.b. The app is used to list, and track the activities. Virtual stickers (see Well Done image for reference) are then given as rewards.
1.c. Once a month we will be sending in surprise stickers for the kids to fill it up in the poster we already sent them. Filling up the poster with colorful stickers again acts as a cue for further activities and rewards.

2. The app -
The link to the app is in this post. If you can set up the app for your kids and reward them with stickers, let me know how it works for them.

I would love feedback in any form or fashion.
