aiwithrajan/touchgrass ? reverse-engineered prompt

Build me an app called TouchGrass that helps people leave the screen and do a real world mission instead.

I want a simple web app with a clean home screen, then a focused challenge flow that gives the user a short personalized task, speaks it out loud, and shows how much time and XP they’ll get. The tasks should feel safe, encouraging, and varied, like going outside, being kind to someone, trying something creative, or exploring nearby. After that, switch into a Zen mode that basically tells them to put the phone away and go do it. When they come back, let them record a quick voice reflection, then show a reward screen with XP, level ups, badges, and a little celebration.

Make it work as a full app with a frontend and backend, and keep it local first and privacy friendly if possible. If you need current docs for anything, look them up online.
