The home screen, meal logging, step counter, reminders and 5 coach messages a day. The detailed program, training, weekly diagnosis and unlimited chat require an active coaching plan.
How is my program built?
Two engines build it on validated physiology — metabolic computation, sports periodization. Then KAI Intelligent recalibrates it every week on your real data, under a medical guardrail.
Does KAI work with my watch?
KAI reads steps, sleep, heart rate and external sessions from Apple Health (iPhone) or Google Fit (Android). If your watch feeds either one, KAI benefits automatically.
