Connect Flo and your coach tracks your cycle phase, so it reads your HRV and resting heart rate in context and adapts training instead of overreacting to a normal luteal dip.


From the periods you log in Flo, the AI derives your cycle length, current phase, and day of cycle, and keeps it in mind on every recommendation.
Your coach normalizes the luteal-phase dip in HRV and resting heart rate instead of reading it as poor recovery and cutting training you could handle.
The coach uses your phase to time hard work, so the plan fits your physiology across the month.
Open integrations on your dashboard, pick Flo and sign in on Flo's own page with the account you use in the app, whether that is Google, Apple or email. Your cycle history imports right away and new entries sync within about an hour. Connecting Flo is the opt-in - there's no separate toggle.
The periods you log (start and end, plus flow when you record it), symptoms, mood, ovulation tests and basal body temperature. It derives cycle length, phase, and day of cycle from these. It only reads your Flo account and never writes to it, and Flo's own predictions are not used.
HRV and resting heart rate vary across the cycle. With your phase in view, your coach reads those signals correctly instead of overreacting to a normal luteal-phase dip.
After every workout and night of sleep, it messages you with the analysis - and what to change. Free for 7 days.
