User reviews

App lagging

App is lagging and not responsive , also pricing became predatory with this company

Suit amazing, but…

I love the suit. I love the technology. I love the results. After one year I am feeling great. And then reality struck…
The subscription that was included with my original purchase had run out and now I am being charged $50 a month for crummy content, stale content, and otherwise little value add for the forced subscription.
It’s a shame that something so special can be tainted by a crummy business model. Unfortunately, without the subscription, the suit is useless.
Sad.
Buyer, beware.

Awesome

Just got the V4 and the whole thing is great. I exercise and it takes a lot to get me sore, This thing got me sore. I was looking for something I could use at home. It takes time to get used to the electric tingling and the first time you suit up it will take you 20 minutes but after that basically 30 minutes total suit up and exercise.

Great product ruined by subscriptions and price increase

Was my favorite exercise product…

DO NOT UPDATE

Latest update broke offline mode. Great, I can download workouts to my device. Great, if I try to workout without internet, the new update immediately logs me out. Absolutely useless feature now. App features and workouts haven’t really changed in 14+ months. Presumably this new “update” was to prevent users from using the hardware without their $1,000 membership. Used to be a raving fan for years. These kinds of updates make me wish I purchased something else. Go with TitanBody, SQAI, or VisionBody instead

FAQ

What is the Katalyst App?

The Katalyst App is a companion to the Katalyst Training System, which uses Electro Muscle Stimulation (EMS) to provide a full-body workout. It controls the EMS impulses delivered through a wearable suit, allowing users to engage up to 90% of their muscle fibers in just 20 minutes with zero load on joints.

What kind of workouts are available?

The app offers a full library of workouts designed by professional trainers for all fitness levels, including strength, power, cardio, and recovery. Users can choose from beginner to advanced programs, or utilize freestyle mode for cardio.

Is the Katalyst App free to use?

The Katalyst App is free to download and use for those who already own a Katalyst System. New users can download the app to preview workouts, but the training system itself needs to be purchased separately from katalyst.fit.

Can I control the workout intensity?

Yes, the app allows for precise control over every aspect of the workout. You can adjust the impulse intensity to push yourself harder, pull back slightly, or target specific muscle groups, ensuring you remain in control of your training.

Can I use the app offline?

Yes, you can preload and store your workouts within the Katalyst App. This allows you to train anytime, anywhere, even offline and without an internet connection, making it convenient for travel or areas with limited connectivity.
