Marble

Gamified screen-time reduction — an avatar that grows when you doomscroll less. Friction before the scroll, then a better next step.

Onboarding

Name the trap first.

Four beats before setup — the hour that started as one check.

Onboarding — The One Thing Trap
01 · Trap You meant to check one thing. An hour later, still scrolling.
Onboarding — Just a Quick Scroll
02 · Blur A quick peek turns into a blur — time already gone.
Onboarding — Take Control
03 · Control Don’t let a five-minute break run the rest of the day.
Onboarding — Reclaim Your Time
04 · Reclaim Turn lost scrolling into moments that actually matter.

Setup

Getting to know you.

Nine steps, skippable. Gender and age first — so the later prompts can fit.

Marble splash
Launch Mint orb, one word — Marble.
Onboarding — select gender
01 of 9 · Gender Male, Female, or prefer not to say.
Onboarding — choose age range
02 of 9 · Age Age band so the experience can personalize.

Friction

Don’t just block. Offer a next step.

When the scroll itch hits — a book, a walk, piano, a stretch.

Recommendations Read, walk, play, stretch — instead of opening the feed.
One step closer to throwing away doomscrolling
Closer One step closer to throwing doomscrolling away. Back to home.
