Calorie tracking has always been hard work.
Calorie tracking has always been hard work.
We’re ending that.
Snap your meal — the best AI reads it in seconds. And unlike every other tracker, BuonApp tells you how sure it is and lets one word from you fix 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 the email tied to your Apple ID: your invite arrives through Apple’s TestFlight. iPhone only, for now.

How it works
Ten honest seconds, start to logged.
2
Get an answer that shows its work
A range with a confidence badge — and every assumption listed, down to “lemon half, not counted as a caloric item.”
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.
4
Or adjust any ingredient
Every detected item has its own grams, calories and macros — slide the amount, rename it, or have the AI recalculate. Ate half? Two seconds, even after logging.
5
Log it in one tap
“Looks right — log it.” The full review only opens when the AI is less sure — that’s where checking actually fixes mistakes.
What’s inside BuonApp?
Everything a tracker should do — 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 and your week every Sunday. And it never polices — it coaches.
On a GLP-1? Our coach knows.
With appetite suppressed, the risk flips: losing muscle, not fat. BuonApp goes protein-first from day one — and on the no-appetite days, the coach protects your muscle by making sure protein is the one thing you never skip.
Syncs with everything you already use
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. Skip a week — nothing breaks.

Snap it, say it, or scan it
Photo, voice, barcode, or a saved favorite — “two taps, no photo, logged instantly.” Ate half? One slider fixes it, even after logging.
Logged it once? Two taps forever
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 a photo, ever.
Pregnant? It plans for two — honestly.
Tell it your due date and the plan follows the clinical energy additions for your trimester, twins included — and refuses to run a deficit, ever. Breastfeeding adds what it really costs. Your midwife or doctor always has the final word.
Rough day? Say it in one tap.
Eight one-tap check-ins — and the whole app responds: 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?
Calorie tracking has always been hard work. We’re ending that — without lying to you about accuracy.
Ten honest 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 you the one thing that fixes it.

No account to create. Your diary and photos stay on your phone — we couldn’t sell your data even if we wanted to.
25–35%
That’s the average calorie error independent studies measured in the best photo-AI systems — an error every other app hides behind one confident number. We’re the tracker that shows it, and helps you shrink it. Same rule for your burn: the plan’s assumption gets checked against what your devices actually measured — skip your workouts, and BuonApp tells you your real deficit was smaller. Honest in, honest out.
