Lumi app icon — a glowing face Coming soon to the App Store

The screen time app with a heart.

Lumi is a tiny light that dims when you doomscroll. Block TikTok, Instagram, or any iPhone app — then say an affirmation to unlock it. Guilt goes to the apps. The light comes back to you.

How Lumi works

1

Block the apps that take from you

Pick TikTok, Instagram, or any app with Apple Screen Time. Lumi shields them with a gentle screen — no cold system wall.

2

Affirm to unlock

Want in anyway? Read, type, or trace one affirmation first — "I am worth more than this feed." A breath between impulse and scroll.

3

Keep her light alive

Lumi dims as your screen time climbs and glows when you stay present. Streaks unlock new environments. Missing a day doesn't break you — light freezes have your back.

Frequently asked questions

What is Lumi?

Lumi is an iPhone screen time app and app blocker led by a small glowing character. Her light dims as your screen time climbs; blocked apps unlock only after you complete a short affirmation ritual. Learn more →

How does Lumi block apps like TikTok and Instagram?

Lumi uses Apple's Screen Time (Family Controls) framework — the same system-level shield iOS uses — so blocks apply everywhere, with a warm Lumi screen instead of a cold system wall. Learn more →

What is the affirmation unlock ritual?

When you open a blocked app, Lumi asks you to read, type, or trace one short self-affirmation first. It takes ~10 seconds and puts a breath between impulse and scroll — then the choice is genuinely yours. Learn more →

Does Lumi shame you for slipping?

Never — it's a design law. If you lapse, Lumi says she waited for you. Streaks come with light freezes so one missed day doesn't erase your progress. Guilt lands on the apps, not on you. Learn more →

Is Lumi free?

The core loop is free: the affirmation ritual, one blocker, your streak, and today's stats. Premium (7-day free trial) adds unlimited blockers, Focus mode, history, and unlockable environments.
