Lumen

Your energy, as light.

A daily energy check-in becomes a private light: on-device generated art living on your Home and Lock Screen widgets. Generated on your iPhone. Nothing you feel ever leaves it.

A calm, anti-dopamine mood app. Universal for iPhone and iPad. No account, no notifications, no noise.

The glance, not another streak

Tap two or three mood words, add a line or a photo if you like, and watch today's Lumen bloom into being. One tap sets it across your widgets, and your phone quietly carries today's light — a daily-changing image you glance at, never an app that nags you back.

Where today's light lives

One tap puts today's Lumen on a Home Screen widget, a Lock Screen widget, or both, and it changes when you check in again. It is a glow widget rather than a wallpaper pack: the picture comes from how your day actually went, so the lock screen art is different tomorrow. Send a friend a mood card from the same artwork, or keep it to yourself.

Made on your iPhone

The daily art is generated on your device — a built-in renderer on every iPhone, with additional Apple Intelligence styles on supported devices. It works in airplane mode. Sharing happens only through the system share sheet, by your hand.

Private by construction

No account, no login, no server. Your check-in is processed on your device and never leaves it.
App Privacy label: Data Not Collected. The only network call is App Store purchases.
No ads, no streaks, no badges, no notification spam. The widget is the point.

Pricing

Free is complete for the daily ritual: your first light and one new light every day, on a Home or Lock Screen widget, forever. Lumen Premium is $4.99 monthly, $39.99 a year with a 7-day free trial, or a one-time $69.99 Lifetime purchase (family-shareable). Restore purchases anytime.

Questions

Does Lumen need an account?: No. There is no sign-up and no login.
Does it work offline?: Yes. The daily art is generated on the device. Only the App Store needs a connection.
Do I need an Apple Intelligence iPhone?: No. Every iPhone generates your light with a built-in renderer; Apple Intelligence adds extra styles on supported hardware.
Is this a mood tracker or health app?: No. Lumen is reflection and art — it makes no health, therapy, or diagnosis claims.
Is it a wallpaper app or a mood app?: Both, in one gesture. You tap a few words for your personal energy today, and the app draws generative art from them for your widgets and your lock screen.
Which widget sizes does it support?: Home Screen widgets in small, medium and large, plus rectangular and circular Lock Screen widgets. Free covers one configured widget; Premium fills every slot and can pin any saved day.
