About this app

Prioritizing "sustainability" above all else. fit-ai is an app designed to help you easily and effortlessly continue your first strength training and food tracking. Without being overwhelmed by difficult numbers, you can build your progress from small steps each day.

■ AI Coach by Your Side
"What should I do today?" "I slacked off..."—Even in those moments, simply talk to your AI coach. It offers supportive guidance, not criticism, helping you plan your next steps.

■ Record Your Training with a Tap
From your training (routine), simply tap today's menu to start recording. Easily record exercises, sets, and weights. Your progress accumulates as "proof of your continued effort."

■ Gently Visualize Your Body's Changes
Recording your weight and body composition allows the "Body Memo" to gently reflect on your progress. Instead of being driven by numbers, it encourages you to take manageable steps towards your desired physique.

■ Effortless Meal Recording
Search for what you ate by name, or record your frequently eaten items with a single tap. In addition to ingredients based on the Ministry of Education, Culture, Sports, Science and Technology's food composition data, popular restaurant meals like ramen and beef bowls are also registered as "guidelines." Barcode scanning is also supported.

■ Set Goals in Small, manageable Steps
Set goals at your own pace, such as "desired weight" or "number of exercises per week." We prioritize consistency over rushing your achievements.

■ Offline Functionality
Records can be made offline and automatically sync when you go online.
