The bottom line
Clue is the most credible period tracker on the market. CycleFit is as credible and as accurate, with the same depth of symptom logging, plus a sports science PhD who programs your training around your phase. Tie on tracking, win on application.
Should you switch from Clue?
Stick with Clue if you only want to learn about your body, you don't have a regular workout routine, and you prefer a tracker that's also on Android.
Switch to CycleFit if:
- You already know the science, now you want to apply it
- You want phase-based workouts, not just articles about phases
- You're paying for Clue Plus but want training, not more content
- You're a regular trainer, runner, lifter, or yogi
Frequently asked
Is CycleFit as scientifically rigorous as Clue?
Yes. CycleFit's training programming is reviewed by a sports scientist with a PhD in exercise physiology, and we cite the same peer-reviewed research that Clue does. We just translate it into action.
Can I switch from Clue without losing my data?
You re-enter your last period date in CycleFit, which takes 10 seconds. The app then rebuilds your cycle pattern as you log, with the same prediction accuracy you'd expect from Clue.
Does CycleFit show hormone graphs like Clue Plus?
Yes. CycleFit shows daily estimates for estrogen, progesterone, and luteinizing hormone, with phase-specific explainers. Live values, not just articles.
