How it works

Three texts in,
you’re tracked.

No more forgetting to log dinner. No more “snap, scan, edit, save.” Calo lives where you already are.

01📱

Save Calo as a contact.

One verified iMessage number. The number stays the same forever.

02🌯

Text him your meal.

Picture, voice note, “a turkey wrap and a coke” — whatever’s easiest.

03🧠

Calo does the math.

Calories, macros, what’s missing from your day, and what to eat next.

Meet Calo

Like a friend.
Trained like a dietitian.

Calo doesn’t just count. He notices patterns, plans your meals, and texts you exactly when it matters.

Snap & log in 2 seconds

Photo in, calories out. Voice notes work too — describe it, eat it, done.

Creamy spaghetti carbonara
carbonara, ~640 cal. nailed your carbs. you good on protein?

Menus, decoded.

Send Calo any restaurant menu. He picks the order that hits your goals.

menu has salmon, pasta, burger. what wins?
Grilled salmon with greens and sweet potato
go grilled salmon + side greens + sweet potato. 520 cal. lowest fat option that still slaps.

The 9pm protein check.

If you’re short, you’ll know. If you’re crushing it, you’ll know that too.

32g shy on protein. greek yogurt + scoop of whey = solved in 2 min.

Loving roasts (when needed).

No shame spiral, just a friend who keeps it real. Calo will absolutely call out the third bag of chips.

i'm getting another bag of chips
respectfully, no you’re not. drink water. tell me what you actually want.

The difference

Calorie apps are a chore.
Calo isn’t.

Calorie apps
  • Yet another icon on your home screen
  • Search a database for the exact granola brand
  • Streaks that punish you for one bad day
  • Push notifications you eventually ignore
  • No actual advice — just numbers
Calo
  • Lives in iMessage — already on your phone
  • Reads your food. Snap → calories. That’s it.
  • No streaks. No guilt. Just steady progress.
  • Texts you when *you* need a nudge, not when an algorithm fires
  • Actual advice from a friend who happens to be a dietitian

I tried five tracking apps. None of them stuck. I’ve been texting Calo for 7 weeks. Down 9 lbs.

The menu thing alone is worth it. I’m at restaurants all week and Calo just tells me what to order.
