Keep the streak going.
Keep Lumi lit.

And you’ll even lose weight.

Lumi counts your calories from a photo of your plate, and your steps from your iPhone. Do both and the streak holds.

  • Meet your step target.
  • Photograph what you eat.

How it works

Two things a day.

Your steps and your meals. Nothing to weigh, nothing to wear.

Steps

Your phone’s pedometer has already been counting for a week. Your first target comes from that.

YOU WALK 3,808 STEPS A DAY ON AVERAGE.
210–340 kcalestimated · tap to correct

Meals

Photograph the plate. Lumi returns the calories and the three macros, as a range you can correct.

MEASURED READS AS A NUMBER. ESTIMATED READS AS A RANGE.
The bar

Miss a day.
Don’t miss two.

A missed target drops tomorrow’s by a fifth. Hold it two days and it goes back where it was.

The drop is temporary. The floor rises with what you’ve held, so a bad week costs a fifth of it at most.

The numbers

Most apps promise a straight line.

Bodies don’t do straight lines.

A calorie deficit buys less every kilo you lose. Lumi runs the model that says so, and names the plateau on day one.

Before you ask

The five questions.

I already log in MyFitnessPal. Do I start over?
No. MyFitnessPal, YAZIO and Lifesum all write your calories to Apple Health, and Lumi reads them from there. What you logged this morning is already in.
Do I need a watch?
No. Your iPhone counts the steps on its own, and it has been counting for the past week. Your first target comes from that week, not from a round number.
What if the calorie estimate is wrong?
Open the meal and change it. The estimate arrives as a range rather than a single number, because a photo cannot do better than a range.
What happens the day I miss?
Tomorrow’s step target drops by a fifth, so it is a day you can meet. Hold it twice and it goes back where it was.
What happens when the free trial ends?
It renews at $99 a year, or $12 a month. You cancel from the App Store, like any subscription.
