AI calorie coach for iPhone
The calorie coach that sees your whole day.
You already know what to eat. The hard part is doing it on a Tuesday, on five hours of sleep, after a hard workout, with nobody watching. Kova watches. It logs your food from a photo, reads your training and sleep from Apple Health, and coaches you from the day you actually had.
Free to start. Your first three days run at full volume, no card needed.
Consistency beats willpower. In a study of 1,685 adults, people who kept a food diary at least six days a week lost about twice as much as people who logged one day a week or less. Kova makes six days a week take under a minute.
Someone has to be watching. People who sent weekly progress reports to another person reached their goal, or got most of the way there, 76% of the time. People who kept the goal in their head: 43%. Kova is the someone, every day.
Your calorie app never asked how you slept. On the same diet, people sleeping just over five hours lost 55% less fat than people sleeping seven and a half, and lost more muscle. Kova reads your sleep and coaches around it.
Why people quit on day nine
A number is easy to ignore. A coach is not.
Nobody stops tracking because the math is hard. They stop because the app hands them a number and nothing else. No one noticed the short night, the hard session, or the streak on the line. So the number stopped meaning anything.
What most calorie apps see
"You have 767 calories left today."
What Kova sees
"Short night, hard session, energy at 4. You need protein tonight, not fewer calories. Forty grams at dinner, then bed before eleven. Your streak is at seven. Keep it."
One day with Kova
Someone is paying attention all day.
You never sit down to "do your tracking." Each moment adds a piece on its own, and by dinner your coach is working from the day you actually lived, including the parts you would have forgotten to mention.
It knew how you slept before you opened your eyes.
Your night syncs in from Apple Health, or you confirm it on a dial in one tap. Either way, your coach starts the day knowing whether recovery is on your side, and adjusts what it asks of you.
Lunch is a photo. That's the whole job.
Point the camera at the plate. Calories and macros land in seconds from real food data. Eat this same lunch next Tuesday and it becomes a one-tap usual. Six days a week of logging stops being a discipline and starts being a reflex.
Your workout shows up without you.
Strength, 45 minutes, logged by your watch and read by your coach. No wearable? Three taps logs it, with a calorie estimate that is labeled as an estimate and never quietly added to your food budget.
Dinner advice from someone who was there.
Built from the short night, the hard session, and what is already on the board. It ends with one concrete action for tonight, because a coach who gives you five things to do has given you none.
You log it. Kova notices.
The action card flips to done the moment your dinner lands. Tomorrow's advice starts from what you actually did. That is the loop that keeps people going past day nine: being seen doing the thing.
Ninety seconds
Is Kova right for you?
Four questions. No email, no sign-up. You get a straight answer, the coach voice that fits you, and what Kova would actually do about the way you usually fall off.
It's the same kind of quiz the app uses to pick your coach, so what you see here is what you'd get.
Logging, without the chore
Ten seconds a meal. Honest numbers.
The people who log most consistently get the best results. So every input in Kova is built to be the fastest honest version of itself. Fast so you keep doing it. Honest so it is worth doing.
Photo scan
Point the camera at the plate. Portions and macros are estimated from what is on it, then matched against USDA whole foods and Open Food Facts packaged foods, so "cherry tomatoes" finds cherry tomatoes. Barcodes work too, and so does just saying what you ate.
Usuals
Kova notices what you eat often and lines it up at the top of logging. Your Tuesday lunch is a single tap on Tuesday, with undo in case it wasn't. Most of your week ends up logged in a few taps.
Workouts
Sixteen activity types, synced from your watch or logged in three taps. Burn estimates are labeled as estimates and never raise what you're told to eat. Tell the coach "I did legs" and it offers to log it. Nothing is logged until you confirm.
Sleep
Synced from Apple Health, or set on a dial each morning: hours and how you feel, ten seconds, skippable. Short nights change what your coach asks of you that day, because they change what your body can do.
And the rest of Kova
A 60-second morning brief in Kova's voice, built from your day: how you slept, what's planned, the one thing that matters today.
Your week, cut into a short recap you can actually watch. What went right, what slipped, what next week should look like.
A picture of your week's plates, generated from what you logged. Seeing a week of food in one image changes the next week.
A five-second energy check-in. Over weeks it becomes the coach's sixth sense: skip breakfast, energy tanks. It has the receipts.
Guided breathwork for the moment the day gets away from you. Two minutes, no account of what went wrong, just a reset.
A heads-up before a streak breaks, a nudge when your usual lunch isn't logged, a morning sleep check-in. Opt-in, capped at two a day, silent at night.
Pick how your coach talks
Same week. Three very different coaches.
Most coaching fails on tone. Too soft and you tune it out. Too harsh and you delete the app. A short quiz during setup picks the voice you'll actually listen to. These are real replies to the same week of data. Change your coach any time in Settings.
You dropped to 92g of protein by Friday, matching your lowest energy check-in of 4/10. Saturday proved you hit 8/10 energy when protein reached 148g. Repeat Thursday's 52g chicken dinner tonight.
Repeat Thursday's chicken dinner: 52g of protein.
Every style gets the same facts and the same advice. What changes is the coach, not the truth.
Built to be trusted
The rules Kova keeps.
You will only follow a coach you believe. These aren't settings you can find. They are how the app is built.
Exercise never inflates your budget
Burn is shown and your coach knows about it, but it never raises how much you're told to eat.
AI only with your say-so
Kova tells you exactly what it shares and asks first. Say no and everything non-AI still works.
