Plain-language logging
Describe the meal like you'd describe it to a friend. AI returns calories, protein, carbs and fat with a confidence range and the assumptions it made — all editable before you save.
Now on Google Play · free while we’re in early access
Log your food the way you’d actually say it.
Every other tracker asks you to scan barcodes and guess portions until you give up. CalsFlow just asks what you ate — “2 boiled eggs, 1 roti and chicken karahi” — and has your calories and macros a few seconds later.
It’s live and free while we’re in early access — every feature unlocked, no card, no ads.
Free to use — and your progress photos never leave your phone.

Try it right now
Type a meal. Get the numbers.
Three free estimates, right here — no account, no download. Nothing you type is saved; it’s just the calculator, so you can see how CalsFlow thinks before you install it.
Powered by the same AI as the app. Targets, streaks and history live in the app — this is just the calculator.
Everything in one place
Built for people who quit other trackers
Most apps make you work for them. CalsFlow does the tedious part — the numbers — and keeps the parts that actually change behaviour: momentum, context and kindness.
Targets built around you
A five-step onboarding turns your body stats, goal, activity level and training split into daily calorie and macro targets — with a local Mifflin-St Jeor fallback when AI is unavailable.
Streaks that forgive
Green, yellow and red days computed on the server so nothing can be gamed. A slightly-off day keeps your streak alive instead of wiping it — because one meal is not a verdict.
Weight & body progress
Weigh-ins, a trend chart, BMI and a realistic projection of when you'll hit your goal. Track waist, chest, arms and more, with optional photos that never leave your phone.
Calendar you can read at a glance
A monthly heatmap of green, yellow and red days with a summary of averages and total change. Tap any day to see exactly what you ate and how it landed.
Your watch counts too
Connect Health Connect on Android and the steps and active calories you earn get folded straight back into today's budget — so a long walk actually shows up as room to eat.

The streak system
A bad day shouldn’t cost you a month
Every day is scored against your own target range — and you can widen or tighten that range whenever you like. Yellow days are a shrug, not a punishment.
Green day
85–110%You landed in your range. Streak grows.
Yellow day
70–120%A little under or over. Streak is preserved.
Red day
<70% · >120%Well off, or nothing logged. A fresh start tomorrow.
A month in CalsFlow — consistency you can see, not a number you dread.

Share the win, not your whole diary
