Sound familiar?

  • Burned 1,200 on a long ride and still guessing what to eat.
  • My watch says one number. My calorie app says another.
  • Under-fuel before the race, binge after it.
  • My diet app gives me the same target on leg day and on the sofa.

Sweatmeal starts where the training does.

From the session to the plate

  1. Sweatmeal profile with device sync - Whoop, Oura and the rest connect so targets flex with your real recovery and burn.

    You train

    Whoop, Oura, Strava, Ultrahuman or Apple Health send in what you actually did: the session, the burn, the recovery. No wearable? It works from your stats and sharpens from your weight trend.

  2. Sweatmeal Today screen - 421 kcal left of 1,726 today, with protein, carbs and fat still to eat.

    You get today's number

    One calorie and macro target for today, built from that training. A hard session opens up carbs, a rest day tightens it, and it never drops below your resting burn.

  3. Sweatmeal coach naming a meal - grilled salmon with rice and greens, 720 kcal, 52 g protein, 85 g carbs, 18 g fat - with a Log this button.

    The coach names the meal

    Ask what to eat and the coach reads what is still open today and what you train tomorrow, then names a specific meal with its macros. Not a lecture.

  4. Sweatmeal food log - the day eaten so far, and a field to type what you ate.

    You log it in a line

    Tap "Log this", type "two eggs and toast" or snap the plate. You see the breakdown before anything counts, and the number updates.

Every target comes from published sports‑nutrition equations, worked out the same way every time. The working is on the methodology page.

And the weeks around it

Races in the calendar

Put your sessions and races in the calendar ahead of time. Fuelling ramps up into race day and settles back after, so race week is not a guess.

A number that learns you

The app watches your weight trend and corrects the burn it assumed, so the target gets closer to your own body the longer you use it.

Questions athletes ask

What is Sweatmeal?
Sweatmeal is an iPhone nutrition coach (Android is coming soon) for runners, cyclists, triathletes and lifters that sets a daily calorie and macro target from the training you actually did. It reads your sessions from a wearable, Apple Health or Health Connect, builds today's number from them, and an AI coach names the next meal that fits what is still open. You log food in a sentence or a photo, and the target recalibrates over time from your weight trend.
How is Sweatmeal different from MyFitnessPal or a calorie counter?
Sweatmeal sets your daily target from how you actually trained, while a calorie counter like MyFitnessPal gives you a fixed number from your bodyweight and goal. A hard session opens up more carbs and a rest day tightens the target, so the number reflects the day you had instead of a flat average. It also suggests the next meal rather than only recording the last one.
Can't I just ask ChatGPT what to eat?
You can, but Sweatmeal computes your calories and macros from published equations and your measured expenditure, the same way every time, where a general chatbot answers each question from scratch. Sweatmeal also keeps the ledger: today's running balance, the week behind it and your weight trend, and it corrects its own maintenance estimate as that trend comes in. A chat answers the question in front of it; Sweatmeal is built to hold a number across a season.
How does Sweatmeal calculate my calories and macros?
Sweatmeal starts from your daily burn, measured by your wearable or estimated with the Mifflin-St Jeor equation, then applies your goal as a deficit or surplus that is cycled around training and never drops below your resting metabolic rate. Protein and fat are set per kilo of a fat-adjusted weight (lean mass if you enter body fat, otherwise an ideal weight from your height); carbs fill the rest, with a floor on training days. The full method and its sources are on the methodology page.
Is Sweatmeal accurate?
Sweatmeal is as accurate as its inputs, and it tells you which numbers are measured and which are estimated. With a wearable connected, your burn is measured; without one, it starts from a validated equation and sharpens as your weight trend shows what your maintenance really is. Photo and sentence logging are AI estimates you review before they count, and Sweatmeal is not a medical device.
Which wearables does Sweatmeal support?
Sweatmeal connects to Whoop, Oura, Strava, Ultrahuman, Apple Health and Health Connect. Garmin is not supported yet. A wearable is optional: without one, Sweatmeal estimates your burn from your body stats and activity and refines it from your weight trend.
What do I need to use Sweatmeal?
Sweatmeal needs an iPhone; it is on the App Store, and Android is coming soon. A wearable gives the most accurate targets but is not required, and Apple Health or Health Connect on its own is enough to bring in your workouts.
Can Sweatmeal help me lose weight while I keep training?
Yes, Sweatmeal is built for losing weight without starving your training: the deficit is larger on rest days and smaller on hard days, and it never goes below your resting metabolic rate. Protein is anchored to your fat-adjusted weight and rises in a deep cut to protect muscle, and training days keep a carb floor. As your weight trend comes in, Sweatmeal corrects its estimate of your maintenance so the deficit stays real.
Is Sweatmeal for runners, cyclists or lifters?
Sweatmeal is for all three, plus triathletes: anyone whose training load changes from day to day. Endurance sessions raise the carb side of the target, strength work is covered by the protein anchor, and the race calendar ramps fuelling up into race day, including a carb-load, and settles it back after.
Can I use my coach's or dietitian's numbers in Sweatmeal?
Yes, Sweatmeal lets you enter fixed calories and macros from your coach or your own plan and tracks you against those, with optional carb cycling on training days. Or keep Sweatmeal's formula and tune it: protein per kilo, how hard the deficit runs, your activity level. Custom targets are free.
Is Sweatmeal free?
Sweatmeal is free to download, and its training-aware targets, wearable sync, trends and race calendar are free. Sweatmeal Pro, a subscription through the App Store or Google Play, covers the AI side: the coach, logging a meal from a sentence or a photo, and meal suggestions. Because meals are logged through the coach, using Sweatmeal day to day needs Pro; the annual plan starts with a 7-day free trial.
Is my health data private in Sweatmeal?
Sweatmeal does not sell your personal data and never uses your food, body or health data for advertising. Messages to the AI coach are sent with zero data retention and are not used to train any model. You can delete your account from inside the app; your data leaves our active systems within 30 days and our backups within a further 90.

Eat to the day you actually had.

Targets, wearable sync, trends and the race calendar are free. Pro adds the AI coach, photo logging and meal suggestions, with a 7‑day trial on the annual plan.
