Everything works together
Six features, one supportive system built around how your body and habits actually change.
AI food interception
Scan a barcode and our AI gently flags red-flag items before you log them, suggesting a kinder swap — never a lecture.
Bluetooth scales
Step on your Bluetooth body-composition scale and your weight syncs automatically. No scale? Snap a photo and we read it for you.
Biological engine
Seven regimens, one smart engine. Whether it's GLP-1 cycles, fasting windows, points or syns, the coaching adapts to your plan.
Smart calendar notifications
Reminders land in your own calendar, timed to your medication cycle and the moments you're most likely to wobble.
Adaptive TDEE
Your calorie targets recalculate as your metabolism shifts, so progress keeps moving even when your body adapts.
Weight forecast
A trend line that sees through daily noise and projects where you're headed — so today's choices feel worth it.
