Kegelia vs Elvie.

Elvie and Kegelia are both apps for pelvic floor training, but only one of them needs a device to work. Elvie pairs its app with an insertable biofeedback sensor; Kegelia paces the exercise on-screen with nothing to buy or insert. We make Kegelia, so here's an honest look at what Elvie does well, and where we're different.

iPhone (iOS only for now)

The short version

Elvie Trainer is a premium biofeedback device: insert it, connect it to the Elvie app over Bluetooth, and your contractions move a gem through a targeted workout in real time. It's CE and UKCA marked on its own labeling, priced around $200, and set up with the Elvie app over Bluetooth. Kegelia is a free-to-start app with no device: a jellyfish paces the rhythm of the exercise on your phone screen.

Where a paced app and an insertable trainer part ways.

Measurement	Measures nothing. A jellyfish shows the movement and a gentle haptic marks each lift.	Tracks pelvic floor muscle movement and tone. Squeeze harder and the gem in the app lifts higher.
Assessment limits	It cannot confirm a contraction happened, verify your technique, or give biofeedback. Not a medical device.	CE and UKCA marked on its own labeling. Its manual says it must not be used to treat conditions.
Cost basis	Free to start, no time limit. A subscription unlocks the longer sessions and higher levels.	A one-off device purchase. Its companion app is a free download.
Setup	Download, choose one, three or five minutes, and start. No questionnaire. iPhone only, iOS 26.0 or later.	Charge it, install the app, clean it, and squeeze three seconds to pair over Bluetooth. iPhone or Android.

What Elvie does well

Elvie's biofeedback gives you something Kegelia doesn't: direct confirmation, through a sensor, that you're contracting the right muscle and how strongly. The brand is well known and well engineered, and the gamified feedback loop (watching a gem move as you squeeze) is a genuinely different, more visual way to learn the movement than pacing alone. For someone who wants that kind of confirmation and is comfortable with the cost and the device, Elvie is a legitimate choice.

Where Kegelia is different

Kegelia doesn't measure your contraction the way Elvie's sensor does; it paces it, and that's a real trade-off we're upfront about, not something we work around with a bigger claim. What you get instead: no device to buy, nothing to insert, and a phone-only setup that can go fully discreet in stealth mode. Elvie's device, however well designed, is still a physical object you have to store, charge, and use somewhere private. It's also built for anyone: Elvie Trainer is designed for vaginal insertion, so it's women-only by anatomy; Kegelia's pacing works the same way for men and women.

Which should you choose?

If you want a premium, gamified biofeedback experience and the cost and device aren't a barrier, Elvie is a well-built option. If you'd rather start today for free, with nothing to buy or insert, and you want the option to practice completely unnoticed, Kegelia is built for exactly that. See how Kegelia compares to Perifit.

FAQ

What's the real difference between Elvie and Kegelia?

Elvie Trainer is an insertable device that measures your pelvic floor contraction and turns it into biofeedback through its app; Kegelia is a device-free app that paces the exercise visually and with haptics, without measuring the muscle.

Is Elvie worth the cost compared to a free app like Kegelia?

It depends what you're looking for. Elvie's sensor gives direct feedback on your contraction that a pacing app can't match; Kegelia gets you started for free with no device, which matters more if cost or simplicity is the priority. How to judge any Kegel app.
