Kegelia vs Elvie: Kegel exercise app or biofeedback trainer?

Elvie Trainer is an insertable biofeedback device run from its app; Kegelia is an app on its own. Elvie measures your contraction with a sensor; Kegelia shows the movement on screen, up and in, 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 and priced around $200. Kegelia is a free-to-start app with no device: a jellyfish on your phone screen shows the movement itself, the bell drawing up and in on the lift and opening on the release, with a haptic on every lift. Elvie shows what your muscle just did; Kegelia shows what the movement should look like. Because it needs only your phone, it works for men and women, in one-minute sessions, and in Secret Mode almost anywhere.

Where an app that shows the movement and an insertable trainer part ways.
	Kegelia	Elvie Trainer
How it guides the lift	Shows the direction: the jellyfish's bell draws up and in on the lift and opens on the release, with a haptic on every lift.	Your contraction moves a gem through a workout in real time.
Where you can practice	Anywhere: in Secret Mode only the jellyfish shows on screen, so a session at a desk or in line looks like meditation.	Somewhere private: the device is inserted, and it needs charging and cleaning.
Who it works for	Women and men, in one app, with no device.	Women: made for one adult woman, used by vaginal insertion.
Measurement	Measures nothing: the jellyfish is a model of the movement, not a reading of your muscle.	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.
Purpose	Built for doing the exercise regularly, in a discreet minute, with no hardware to buy.	An exercise tracker for the pelvic floor, made for one adult woman to use at home.

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 way to learn: it shows what your muscle just did, while Kegelia shows what the movement should look like. 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 shows the movement you're aiming for, and that's a real trade-off we're upfront about, not something we work around with a bigger claim. What you get instead is the target movement in front of you on every rep: the jellyfish's bell draws up and in on the lift, the opposite of bearing down, and opens fully on the release, with a haptic on each lift. There's no device to buy, nothing to insert or clean, and a phone-only setup that Secret Mode keeps private in plain view: the controls disappear, the jellyfish stays, and it looks like meditation. Sessions start at one minute, stopping early still counts, and there are no streaks. Elvie's device, however well designed, is still a physical object you have to store, charge, and use somewhere private. Kegelia is also built for anyone: Elvie Trainer is designed for vaginal insertion, so it's women-only by anatomy; Kegelia 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 the target movement shown on every rep, nothing to buy or insert, and the option to practice completely unnoticed, Kegelia is built for exactly that. See how Kegelia compares to Perifit.

One exception applies to both: if your trouble is pelvic pain, tightness, or muscles that won't let go after a squeeze, rather than weakness, neither a guided app nor a biofeedback trainer is the place to start. See a pelvic floor physiotherapist first; for a tight floor the work is learning to release, not squeezing more.
