Photo, voice, barcode, a search of the product database, or a saved favorite — “two taps, no photo needed.”

Calorie tracking has always been hard work.
Calorie tracking has always been hard work.
We cut the work — not the truth.
A calorie tracker that admits when it’s guessing. Snap your meal — the estimate, the range we measured on weighed meals, and the assumptions you can correct — and one line from you sharpens what no photo can show. No account. No busywork.
Early access is free — you get the app before everyone else and help shape where it goes. Use an email you actually check: a quick confirmation link lands there first, then your invite. iPhone only, for now.
- Measured ranges instead of pretend-exact answers
- One line sharpens what the photo can’t show
- Your diary is never stored on our servers
How it works
From plate to logged in seconds.
2
Log it in one tap
“Looks right — log it.” The full review opens when the AI is less sure — or whenever you want to see the math: every item and every assumption it reports, one tap away.
3
Say what the photo can’t show
One line — “0% yogurt”, “big slice” — and it re-reads the meal with your correction. Your answer becomes its own line item, never hidden math. In the dinner shown here it corrects the fish itself — the AI guessed sea bream; the menu line makes it sea bass, and the numbers follow. Sometimes the total barely moves instead — that, too, is worth knowing.
4
Get an answer that shows its work
The re-read answer, showing its work: a range with a confidence badge — and the assumptions spelled out, down to “cooking oil/butter used for pan-frying fish and sautéing greens not fully visible.”
5
Or adjust any ingredient
Each item the AI detected has its own grams, calories and macros — slide the amount, rename it, have the AI recalculate, or type the label’s own calories and macros for that amount; anything it missed, you add with one described line. Ate half? One slider, even after logging.
What’s inside BuonApp?
The tracking essentials — done in seconds, not minutes.
Your restaurant wingman
Photograph the menu and ask. The coach knows what you’ve eaten today and picks what fits the macros you have left — with an ordering tip.
A coach in your corner, all day
Not just at restaurants. The coach knows your targets, your meals and your training — ask it anything, by chat or voice. It reviews your day every evening, your week every Sunday, and your month at the end of it. It’s built to coach, not punish.
On a GLP-1? Our coach knows.
With appetite suppressed, eating enough protein gets harder — and losing muscle along with the fat becomes a real concern (enough protein and resistance training are its best defences). BuonApp goes protein-first from day one — and on the no-appetite days, the coach helps support muscle retention by keeping protein the one thing you never lose sight of.
Syncs with Apple Health, WHOOP and your own iCloud
Weigh-ins flow in from your scale via Apple Health; every meal flows back. WHOOP adjusts your day. A home-screen widget keeps the score. And on a new iPhone, BuonApp offers to restore your synced diary from your own private iCloud — no account to create. Miss a few days? Pick up right where you left off.

Snap it, say it, or scan it
Photo, voice, barcode, a search of the product database, or a saved favorite — “no photo needed — two taps to log.” Ate half? One slider corrects it, even after logging.
Logged it once? Two taps next time
Save any meal as a favorite and re-log it instantly — or type three letters in the search box. Yesterday’s dinner, last week’s breakfast: repeat any day’s meal without taking another photo.
Pregnant? It plans for two — honestly.
Tell it your due date and the plan applies the energy additions recommended by widely adopted US clinical guidelines for your trimester, twins included (recommendations vary by country) — and refuses to run a deficit, ever. Breastfeeding adds the guideline-based allowance. Your midwife or doctor always has the final word.
Rough day? Say it in one tap.
Eight one-tap check-ins — and the coach, the week review and your streak respond: the coach switches to kind alternatives (a walk, water, a protein snack — never punishment), the week review finds the pattern (“3 of your 4 over-target days were high-stress days”), and a sick day never costs your streak.
Why BuonApp?
BuonApp cuts the logging work without hiding the uncertainty.
Done in seconds
No weighing, no database hunts, no typing fourteen ingredients. Snap, glance, log — done before the food gets cold.
It admits when it’s guessing
Every estimate carries its range and confidence. When it’s unsure, it says so — and asks for the detail most likely to sharpen the numbers.

No account to create. Your diary is stored on your iPhone — and, whenever iCloud sync is on, your private iCloud — never on our servers. AI requests carry only what that request needs, through our relay, which never stores it.
23–36%
That’s the average calorie error recent evaluations measured in leading multimodal AI models — the studies are linked on our honesty page. As of our June 2026 check of eight leading trackers, none displayed a meal-level range on its AI estimates. We show ours — and help you shrink it. Same rule for your burn: the plan’s assumption gets checked against what your devices estimated — skip your workouts, and BuonApp tells you your deficit was smaller than planned. Honest in, honest out.
