What Flo does well

  • Massive user base and a polished, mature product
  • Pregnancy mode, fertility window, and partner mode
  • Large library of cycle and lifestyle content
  • Available on both iOS and Android

Where CycleFit goes further

  • No workout library, every fitness suggestion is generic
  • Cycle data informs you but doesn't change any training plan
  • Premium tier is mostly more content, not more action
  • Built for tracking and education, not for athletic performance

The bottom line

If you only track your cycle, Flo and CycleFit are equally accurate. If you also train, CycleFit is the obvious pick because Flo stops where the article ends and CycleFit picks up with a workout you actually do.

Should you switch from Flo?

Stay with Flo if you're trying to conceive, are pregnant, or want a community-focused experience and don't train regularly.

Switch to CycleFit if:

  • You want the same tracking accuracy but with workouts that match your phase
  • You're tired of generic fitness advice in Flo's articles
  • You want one app for cycle and workouts, not two
  • You value privacy and want your data to stay on your device

Frequently asked

Is CycleFit as accurate as Flo at predicting my period?

Yes. CycleFit uses the same scientifically validated prediction models. With 2 to 3 cycles of data, you'll get the same accuracy as Flo and the algorithm keeps improving with every log.

Can I use both Flo and CycleFit?

Some women do, especially during pregnancy. But for general cycle tracking and training, CycleFit covers both jobs so you don't need to maintain two apps.

Does CycleFit have a fertility window like Flo?

Yes. CycleFit shows your fertile window and pregnancy probability for cycle awareness. We just don't have a dedicated pregnancy mode like Flo, that's not our focus.
