GLP-1 Macro Tracker for iPhone
Protein first.
A macro tracker for people whose appetite has changed, including anyone using GLP-1 medication. A quieter appetite needs a clearer protein signal.

How it works
Log a meal in seconds. Review every estimate.
02
Barcode
Read a packaged food barcode and confirm the serving.
03
Text
Describe the meal in your own words, then edit the result.
AI estimates are informational and may be inaccurate — you can review and edit every result before saving it.
The signal
One number worth protecting.
A clear daily protein target keeps the next choice simple. Set your target, then follow the ring meal by meal.
The next small win
Built for days when eating is hard.
Small portions, soft foods, zero guilt. Calo’s coach uses your logged context to tailor suggestions.
Privacy
Your health profile is stored on your iPhone.
AI requests are sent through our proxy when you use an AI feature. They may include meal names, targets and macros. Nutrition observations that omit your name and email may be retained to improve estimates.
- On your device — food logs, weight, medication mode, progress photos.
- Through our proxy — scan photos or text, meal names, targets, macros and the context needed for requested AI features.
- Never collected — your name, email, or health profile as analytics.
One clear signal, one small choice at a time.
Keep protein in view when appetite feels different.
- What it does
- Logs a meal from a photo, a barcode or a few words, estimates its protein and macros, and lets you edit every estimate before you save it.
- Who it’s for
- People whose appetite has changed, including anyone using GLP-1 medication, who want protein to stay in view.
- What it costs
- Free to download, with manual logging and food database search included. Photo, barcode and text logging, the coach and meal plans need Calo Premium: weekly, monthly or annual plans with a free trial for new subscribers, or a one-time lifetime purchase. The App Store shows the price in your currency before you pay.
- What you need
- An iPhone with iOS 18 or later. Apple Health is optional: Calo reads steps, activity and weight, and writes nothing back.
