It’s the invisible exercise everyone is doing.

Designed for men and women, Karis is the kegel trainer that’s discreet and effortless. And, dare we say, fun.

Stronger pelvic floor muscles may improve intimacy, childbirth, post-pregnancy, incontinence, and more.

A Karis session just takes a couple minutes.

A gorgeous animation guides muscle contraction and relaxation. And there are 2 color themes to choose from.

Indulge at home, in meetings, or on the go. Or during a bad date, your kid’s birthday party, or the DMV line. Careful, you might get hooked.

Notifications don’t use words like “kegels” or “pelvic” to avoid delightfully awkward moments. Your health is your business, after all.

7-day streaks unlock an appearance by the famous Kegel Eagle to recognize your efforts.

*WatchOS app integrates with HealthKit.

Okay, but not exactly what I was looking for

I like that I can set reminders and I like the haptic feedback. But, I wish I could personalize it more. I was given specific instructions for Kegels by my physical therapist, and it would be nice if I could make adjustments for the hold/release times. For example, I want to do 10 reps where I hold for 10 seconds then relax for 10 seconds. Then I want to do quicker hold 2 and relax 2 seconds for 10 reps.

Thank you for the update! I love the new change!!

Excellent design, super useful (new mom!)

Beautifully designed and super easy to use. As a new mom, I can see how these exercises would have been great for expecting moms to practice their kegels. Visually very appealing to use. I like the small vibrations the phone makes to hemp remind the user to do their exercise. Well done!


Apple Watch App leaves something to be desired

Nice app overall, I just wish the app on Apple Watch would keep the watch awake while running. All too often, I’ll start an exercise, only for the watch screen to go black and the vibration to stop. It’s a bit inconvenient to have to keep awkwardly move my wrist to keep the watch awake, especially since I’d prefer to multitask while doing an exercise. Otherwise, pretty nice app.

Glad you enjoy the app and thanks for bringing this issue to our attention! Please let us know what you think of our latest update, which should address the issue. While Apple won’t let us keep the screen on during an exercise, we were able to make it so the sound and vibration continues in the background.

Feel free to contact us here or at with any additional questions or feedback. Thank you again!
