Fitzy — AI Personal Trainer
AI will support your daily training and meals together.
AI trainer is exclusively for you
Based on your goals, physique, and training history, today's advice is displayed on the home screen every day. You can talk to us at any time via chat. The trainer's personality (hot-blooded, cool, friendly, etc.) can also be customized to your liking.
Instantly record meals with a camera
Just by taking a picture of the food, AI automatically analyzes the calorie and PFC balance. You can also record it by entering text, and you can check your daily calorie intake at a glance.
Full-scale management of workouts
Record the number of events, sets, weight, and number of reps. You can train efficiently by simply creating a routine and calling it every time. Monitor your heart rate in real time in conjunction with your Apple Watch.
Healthcare cooperation
Weight, body fat percentage, and workout history are synchronized in both directions with the health care app. Data recorded by other apps will also be automatically imported.
Calendar and summary
Look back at the daily records on the calendar and confirm the growth with weekly and monthly summaries. AI also generates feedback for the entire period.
