For iPhone and Apple Watch
FitWinner calculates your daily calorie target, your training plan and a form score that reflects your recovery directly on your phone, using the information you share during setup and your daily logs. These calculations aren't guesses; they rely on methods used in sports science and nutrition research. If you'd like, the AI can also interpret these results for you and explain, in plain language, what you might focus on over the coming days.
From football to yoga
Whether it's football, running, yoga or a session at the gym, every workout you complete or add to your calendar updates that day's calorie target. On training days you see the energy your body needs, and on rest days a more balanced target. Once notifications are on, the app sends these reminders around your training time: a carb-focused, low-fat meal suggestion about two hours before the session; a reminder of the day's plan as early as you chose; fluid and electrolyte reminders for sessions longer than 60 minutes; a recovery meal with protein and carbs afterwards; and a carb-loading suggestion the evening before a match. The gram amounts in these notifications are calculated from your weight.
The energy a workout uses is calculated from the type of sport, how long it lasted and how hard you pushed yourself. If your Apple Watch measured your heart rate during the session, that measurement is used. Active calories your watch has already recorded are never added a second time, so the same activity doesn't count toward your target twice.
The values in this calculator are an example for someone weighing 75 kg. The app uses the same formula with your own weight: (MET × effort factor − 1) × weight × hours.
Once you turn on workout reminders in the Calendar, you can choose whether they arrive 30, 60, 90 or 120 minutes before a workout. The workout time comes from the time you entered for that day when adding it to the calendar, or from your general training time if you didn't. Nutrition reminders are set around the same time: a light meal about two hours before training, fluids at the start of workouts longer than 60 minutes, a recovery meal half an hour after you finish and a carb-loading reminder the evening before a match. You can choose to receive electrolyte reminders in the summer months, always or never. Skipped workouts don't get notifications, and when your plan changes the reminders are rearranged automatically.
Examples of the notifications the app sends; gram amounts are calculated for someone weighing 75 kg. They are all scheduled on your phone; nothing is sent from a server.
AI insights
Your form score is built from several components, such as sleep, fatigue, muscle soreness, stress and training load, and these numbers aren't always easy to interpret one by one. The AI identifies what is affecting your form most and explains, in a few sentences, what you might focus on over the next one to three days. “How your week is going” in the Calendar summarises your weekly plan in the same way.
Coach
The Coach summarises how your day is going and, when you ask about your remaining calories, your sleep, your next workout or how your week is going, answers based on your own data. You can log the water you drink and the food you eat without leaving the chat. The Coach's answers are prepared directly on your phone, without being sent online.
How it works
Your daily calorie target is calculated from your age, weight, height, occupation and training load using widely used formulas. Active calories and workouts measured by your Apple Watch are added automatically, and you can clearly see every line of the calculation, from your basal metabolism to the contribution of your training.
You can search thousands of foods from Turkish and international cuisines and choose your portion in bowls, pieces or grams. When you add the ingredients of a recipe you've made at home, total calories and macros are calculated from the values in the database. Values that aren't exact are marked as estimates in the app.
Each day, a short check-in lets you note your sleep duration and quality, fatigue, muscle soreness and stress; if your Apple Watch is connected, your resting heart rate and HRV are taken into account too. Today's values are compared with your own values from the last 28 days rather than with other people's, the balance of your training load over the past week is added with a smaller weight, and the result becomes a form score between 0 and 100. Your first score appears after at least seven days of check-ins and is shown with lower confidence during the first two weeks. On days when the score is low, that day's workout is made lighter.
Your training calendar, weekly plan and training load sit together on a single screen. In the days before a match or race you've added to your calendar, the training load is gradually reduced and those days are marked in your plan. Food suggestions also adapt to that day's workout and your remaining calories.
Quick setup
Every piece of information you share during setup is used to calculate your daily target, and none of it is tied to an account. In the final step, the summary shows line by line which information your target is based on and how it was put together.
And more
Suggestions change with your workout and remaining calories. They are all chosen from the food database, and foods you've said you avoid are never suggested. Refresh the list to see different options.
Log water, tea, coffee, mineral water and drinks with calories. Drinks such as ayran, milk or juice are added to your food log as well.
With your permission, your workouts, steps, sleep, heart rate and weight are brought in automatically. FitWinner only reads this data, and you choose which types to share, one by one.
In the knowledge base, each supplement is described together with the strength of the scientific evidence behind it, so you can see which may be relevant to your goal and which you may not need. Supplements that don't suit your health aren't listed. We recommend talking to a healthcare professional before using any supplement.
When you press and hold a workout reminder, the options “Done” and “Snooze 15 min” appear. Tapping “Done” logs the planned workout and updates your daily target; snoozing brings the same reminder back 15 minutes later. Weigh-in reminders offer a direct “Weigh in now” option.
Create your own training programs with sets and reps, and add exercises easily from the exercise list.
PremiumIt never makes a diagnosis. Your answers are only used to make your goals safer; for example, no calorie deficit is applied during pregnancy. When appropriate, it refers you to a specialist.
Your privacy comes first
You don't need to create an account or share your email address to use the app. The information you enter and your logs are stored on your phone; only with your permission is a short, anonymous summary sent for AI comments.
Your calorie target, macros and form score are determined by the calculation engines on your phone. Because these calculations follow the same rules every time, entering the same information always gives the same result, and you can see how that result was reached.
Comments are prepared only with your permission, from a summary with your name and identifying details removed. You can withdraw permission at any time, and comments made from that data are deleted too.
Frequently asked questions
FitWinner is currently in closed beta. We'll announce it on this page when it becomes available on the App Store.
No, it isn't required. Calorie tracking, food logging and your training plan all work without one. If you connect Apple Watch or Apple Health, your resting heart rate, HRV and sleep are included in your form score.
Only with your permission, it interprets your form score and plan in short notes and estimates foods that aren't in the database. The AI doesn't perform the calculations; your calorie target, macros and form score come from calculations on your phone.
Your name, email address and account details are never shared, and the app doesn't use accounts at all. With your permission, a short, anonymous summary is sent, such as workout type and duration and your recent form scores. If you withdraw permission, comments made from that data are deleted too.
Comments prepared on your phone are free. Detailed AI comments, plan explanations and food estimates are part of Premium, and all of them are optional.
No. FitWinner is for people aged 18 and over. It isn't a medical device; it doesn't diagnose or recommend treatment. If you have a health condition, we recommend discussing your goals with your doctor.
