Features
Built around one question: how much is left?
Your day in one number
Calories left is the biggest thing on the screen. Tap it to see what you’ve eaten. Protein, carbs and fat each get a ring, a color and an icon. Glance, close, keep going.
Keep eating while it thinks
The camera closes the moment you snap. Your meal finishes on Home while you get on with lunch, and shows up there when it’s done. Lost signal? Tap retry on the card.
A plan that fits you
Answer a short quiz about your body, goal and pace. Get daily calorie and macro targets, and change any of them whenever you like.
Progress you can see
Log your weight and see it next to your plan. One line tells you if you’re ahead or behind, and how much to eat to catch up.
Barcode, label or words
Packaged food is quickest by barcode or the nutrition label. No photo? Just describe what you ate.
Simple on purpose
What we left out is a feature.
CalSimple is a simple calorie tracker with one job: show what you ate and how much is left. Anything that slows that down didn’t make it in.

Download for iPhoneHow accurate is a photo estimate?
It’s an estimate, like eyeballing a portion, only faster. Every entry lists the ingredients and amounts it counted, so you can spot what’s off and fix it in a sentence or edit any number.
Can AI count calories from a photo?
Yes, as an estimate. Take one photo and CalSimple names each food and its amount, then works out the calories, protein, carbs and fat. You see every ingredient it counted, so if a portion looks wrong you can fix it in a sentence, like “half the rice”.
Can I scan a barcode or a nutrition label?
Yes. Packaged food is quickest by barcode, or snap the nutrition label. No photo? Describe what you ate, like “two slices of pepperoni pizza”.
What can I do without a subscription?
You get a few free scans every day, and they come back the next day. Manual entry, weight logging and your progress charts are free and unlimited. To scan every meal, get CalSimple Premium.
How does the free trial work?
The yearly plan starts with 3 days free. We remind you on day 2, and you’re only charged on day 3 if you haven’t cancelled. Cancel in your iPhone’s Settings under Subscriptions. Monthly and Lifetime start right away, without a trial.
Can I pay once instead?
Yes. Lifetime is a single payment that unlocks Premium for good, with no subscription to renew or cancel. It’s tied to your Apple ID, so Restore purchases brings it back on a new iPhone.
Which iPhone do I need?
Any iPhone running iOS 17 or later.
What happens to my meal photos?
They’re stored privately with your account so you can look back at past meals. Delete your account in Settings and every photo and entry is removed.
Is CalSimple medical advice?
No. CalSimple is a tracking tool. Talk to a doctor or dietitian before making big changes to how you eat.
