Subten is an app for people who train and want an overview of their food, training, and recovery. It combines a calorie counter, a training plan, and an AI fitness coach.

Food and calories
Log food by searching the food database or scanning a barcode, then choose a portion. With Premium, you can photograph a meal, a nutrition label, or a recipe instead. Subten estimates the calories and macros with AI and marks each item as a database value or an AI estimate, so you can check and correct it. A photo estimate can be inaccurate, especially for soups and sauces.
As a calorie counter and macro tracker, Subten tracks protein, carbs, fat, and fiber and shows how much is left for the day. Your daily target is based on your profile and activity, and carbs are distributed across hard days and rest days according to your training plan. With regular weigh-ins, you see a weight trend and an estimated date for reaching your goal.

Training
Build your own workout plan from a library of 244 exercises, or add an exercise of your own. The library has animated demonstrations and step-by-step instructions. Your workout history and personal records are saved in the app. The plans for 8 sports (running, swimming, cycling, triathlon, football (soccer), ice hockey, tennis, and basketball) combine strength and conditioning work across the phases of the season. The sport plans and ready-made gym programs are part of Premium.

Recovery
For the recovery score, Subten reads sleep from Health Connect and, with your permission, HRV and resting heart rate. The score (0–100) also takes yesterday’s hard workout into account and helps you decide whether to train hard today or ease off. Connecting Health Connect is optional.

AI coach and meal plans (Premium)
The AI coach answers questions about food, training, and recovery based on your data, and prepares daily and weekly reviews. The AI meal plan covers a full day based on your goals and preferences, and you can create a shopping list from it.

Widget and water
The home screen widget shows today’s calories and water. Once you add the Quick Settings tile, one tap logs 250 ml of water.

Free and Premium
Free: food logging, barcode scanning, your own training plan, exercise library, workout history, recovery score, widget, and data export.
Premium (monthly or yearly subscription on Google Play): AI coach, AI food recognition from a photo of a meal, nutrition label, or recipe, gym programs, plans for 8 sports, and AI meal plans with a shopping list. The subscription renews automatically and can be canceled in Google Play.

Privacy
No ads and no third-party tracking tools. We do not sell your data. Your records stay on your phone, and the app does not sync them to the cloud. Data is sent to AI only with your consent, which you can withdraw at any time. It is sent through our server to OpenRouter (USA) without your name or email. We do not store the content you send; only an AI answer that you report yourself is saved. Search text is sent to Open Food Facts when our database finds fewer than 3 matches, and a barcode is sent when it is not in our database. A free account is required to use the app.

For adults (18+). Subten is not a medical device and does not replace medical advice; all values are estimates.
Subten is a product of Syenit, s. r. o. (Slovakia).
