Yes: connect Oura in Settings and Rhythm reads your recovery signals and overnight temperature trend from it to adjust how confident today's suggestion is, and on a clearly low day to suggest a lighter weight, never a heavier one.
Once connected, Rhythm reads a daily summary: your recovery signals, your sleep, your activity and calories, your heart rate and heart-rate variability (the beat-to-beat change in your heart rhythm), your breathing rate, your resilience level, any days you turn on rest mode, the start time and calories of your latest workout, and how far your overnight temperature sat from your own recent baseline. If you tag period days in Oura, Rhythm passes those tags to your phone and does not save them on our servers. The full list is in section 2.5 of the Privacy Policy.
When the signals are clear and consistent, today's suggestion is offered with more confidence; when they are thin, or two devices disagree, Rhythm says so instead of guessing. Your logged sets set the weight. On a day your signals read clearly low, Rhythm can suggest a lighter one, never a heavier one, and the number you lift is always yours to type.
Rhythm never shows Oura's own scores back to you. What you get is Rhythm's plain-language read on your day, not a number to interpret.
Rhythm does not pin your ovulation on a temperature reading. That is a deliberate choice, not a missing feature — the app used to do it and we took it out. One night is never enough, no study has put a finger sensor and a wrist sensor on the same person across the same cycles, and the validated research is about cycles where ovulation happens. If you are on hormonal contraception, have PCOS, are in perimenopause, or your cycles are irregular, a temperature trend is much weaker evidence. Your phase in Rhythm comes from the dates you enter, is worked out on your phone, and is never sent to our servers.
For anything about getting pregnant or about contraception, talk to a doctor, midwife or nurse. Rhythm is a training log, not a fertility tool, and nothing here is medical advice.
