Strength, power, balance speed all in one. ### 5/5 — I hacked my workouts! *2022-08-27* I have worked out most of my adult life. But injuries over the years have made me decrease the intensity and consistency of my workouts. To add to the herniated disc in my neck, the back pain from pulled muscles (30 years ago!), and knee pain; recently found out I have a partially torn rotator cuff. These problems have caused periods where I didn’t or couldn’t push through the pain. Now I’m 62 and losing muscle mass so maintaining my strength, conditioning and my shape (let’s face it; that is still important) is really hard. With the Katalyst, I’ve gotten intense workouts in just 20 minutes with no residual joint pain. I follow up with cardio. I feel the same muscle soreness as I did with strength training. And after 2 weeks, I’m starting to see toning in my mid section; an area I was really beginning to struggle with. It took me a few workouts to figure out my best intensity level. I know it’s early; but I am really pleased with my purchase and the results so far. I especially like how easily I can travel with it, which I do quite often with my job. ### 5/5 — Amazing workout! *2022-07-14, version 1.10.0* Best workout ever! ### 5/5 — Best Workout *2022-06-30, version 1.9.1* I have been training for 30years. In gyms, studio classes and at home. I have never been so challenged or felt stronger in my life. Thank You Katalyst. ### 5/5 — I replaced all my free weights with this *2022-03-31* I love it! I used to work out four times a week with weights for an hour. Now I work twice a week for 20 minutes and am stronger without any injury. And my back pain is gone. Thank you Katalyst , ### 5/5 — Intense and Effective Workout *2021-07-20* Great workouts with knowledgeable trainers. Twenty minutes is all it takes to get the strength training your body needs. The dynamic workouts are fun, effective, and intense. ### 5/5 — You should try this out - it’s the future of workout *2021-07-14* I’ve been doing a very similar workout in Berlin, Germany 7 years ago, it was in studio with a personal trainer. I fell in love with the efficiency as 2 days after 20 min training you get a crazy muscle ache for 2 days as if you would have spend a couple of hours in a gym. Katalyst takes this to the next level by 1) making it available at home 2) making it much cheaper compared to the cost of personal training 3) adopting EMS to cardio, as well as post training workout and a great variety of muscle/body workouts I love it, you should give it a try if you are thinking about it, it truly works! ### 5/5 — A magical, life changing training *2021-07-12* I love my Katalyst! As a professional with a crazy busy schedule and a lot of travel, I love my Katalyst. It is so effective and reaches areas of my body, I did not know I had muscles in. 😅 I used to have a lot of back pain, but these are literally gone, since I use this. The thing I love most is that I can travel with it. It packs crazy small and in COVID times and closed hotel gyms, this is a blessing. Simply amazing! Thank you!!! ### 5/5 — Works Great *2021-04-29, version 1.5* Excited to use new version of the app! ### 5/5 — I LOVE THESE WORKOUTS! *2021-04-08* If you are someone who just wants to get your workout done quick and effectively from your own home or you want to build muscle and feel STRONG without having to pick up a dumbbell, you will love Katalyst. The workouts are so fun and I love that they have so many different workouts to choose from! I’m a fan! ### 5/5 — Awesome *2021-04-01, version 1.5* Love the workouts, waiting for more variety ### 5/5 — Most Efficient & Effective workout of my life *2021-04-01* After 15 years as a sports performance coach, I can honestly say Katalyst is the most efficient and effective workout of my life. Since there is zero load placed on the joints, I’m able to charge hard the next day without risk of plateau or injury. 20min sessions that engage over 90% of my muscle fibers make Katalyst an imperative part of my fitness routine. I needed a workout that was effective, efficient, and sustainable. I’ve found it all in one system! ### 5/5 — Best Workout Ever *2021-03-31* As an avid weightlifter, I believe that Katalyst is hands down the best workout on the market. It’s an absolute game changer. A 20 minute, no impact workout is equivalent to 2 hours in the gym! The trainers are super motivational and you can tell they’re also working hard with you! I’ve never felt stronger in my life. Thanks Katalyst! ## Most critical reviews (10 lowest-rated) ### 1/5 — App lagging *2026-06-27, version 2.0.16* App is lagging and not responsive , also pricing became predatory with this company ### 1/5 — Great product ruined by subscriptions and price increase *2026-01-20, version 2.0.8* Was my favorite exercise product… ### 1/5 — DO NOT UPDATE *2026-01-19* 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 ### 2/5 — Very buggy *2021-11-14, version 1.6.0* Oftentimes this app just freezes. It needs lots of work ### 3/5 — Would love a goals feature *2024-01-14* Really great overall. Would love to be able to see a goal: lose weight, gain strength, run further, etc, and it picks workouts and sets a schedule. And something where I can track those goals overtime. ### 3/5 — Three star app - Five star product *2023-09-17* The app is frustrating in a few areas. You can’t save your favorite workouts. So you need to scroll through dozens of videos to find your favorites. Also, why can’t you pause the program to adjust the intensity levels and muscle groups rather than being forced to do this while the program progresses? Being forced to make all adjustments while the electric impulse surges through your muscles every 4 seconds is not ideal. And unless I’ve missed it, I can’t seem to figure out how to set the overall intensity level BEFORE the workout starts. I’m having to hit the “+” button over and over to raise the starting intensity from single digits to triple digits. The workout itself however is 5 stars. ### 4/5 — Suit amazing, but… *2026-05-13* 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. ### 5/5 — Awesome *2026-02-17* 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. ### 5/5 — A great way to exercise *2025-03-27* I love my suit and the app - it’s a great way to exercise, especially the fact that it is low impact. I hope the brand and concept continue to grow. I’ve seen noticeable results! ### 5/5 — Transformed my physicality *2024-10-01, version 1.23.4* Been using EMS for 5 months now and I can safely say it healed my back pain and fixed my core. ## Most praised reviews (7 highest-rated) ### 5/5 — Katalyst Rocks! *2024-07-29* I am thoroughly impressed with Katalyst, a fitness app that truly delivers on its promises. Unlike many other products in this category that often overpromise and underdeliver, Katalyst stands out by providing an exceptional user experience. One of the key highlights of this app is its 20-minute workouts, which are not only highly effective but also easily adjustable to suit your current energy levels. The setup process for the suit may require a session or two to get accustomed to, but once you've got the hang of it, it takes just a couple of minutes to get ready for your workout. I wholeheartedly recommend Katalyst to anyone looking for a (supplemental) top-notch fitness solution. However, there are a few areas where the app could be further enhanced: 1. Workout Progress Tracking: When engaged in a workout series, it would be beneficial to have a progress check mark or indicator to easily identify which workouts have already been completed. 2. Cross-Device Synchronization: Currently, the Apple Watch app only functions when the workout is initiated or displayed from the iPhone. As an iPad user, I would greatly appreciate the ability to sync workouts between devices. It would be fantastic if the iPhone app could mirror the iPad's workout session without playing the video, allowing iPad users to access Apple Watch controls seamlessly. 3. Emergency Off Function: During the final minutes of some workouts, the intensity can reach quite high levels, which is generally a positive aspect. However, implementing a simple "emergency off" function would be a valuable addition, particularly in cases where users experience severe cramping or other health concerns that require an immediate stop. 4. Calorie Burn Synchronization: Integrating an approximate calorie burn calculation that syncs with Apple Health would be a welcome feature. This would provide users with a more comprehensive overview of their fitness progress and help them track their overall calorie expenditure. Despite these potential improvements, Katalyst remains an outstanding fitness app that delivers highly effective workouts in a compact and adjustable format. Its user-friendly interface and efficient workout structure make it a top choice for anyone seeking to enhance their fitness routine. In conclusion, I highly recommend giving Katalyst a try. With its impressive features and potential for further enhancements, this app is poised to revolutionize the way we approach our daily workouts. ### 5/5 — My butt doesn’t jiggle anymore *2024-06-22, version 1.22.5* Katalyst is made it so much easier to work out in 20 minutes. I’m done. I am a business owner, mom, housewife and everything else and sometimes I get too busy or just too tired to work out. Now I have zero excuses and this thing actually works. Yes it does feel like I’m cheating because it’s only 20 minutes, but if you’re doing it right, you’re sweating like crazy and getting the most efficient workout. I feel more firm and because of that I eat less so I think I’ve lost weight since I started the Katalyst. I guess it goes back to the more muscles. You have the more calories you burn. And Katalyst has helped me with keeping my muscle tone. ### 5/5 — Workout Hack *2024-03-02* Addendum to review below. Since the latest app updates, my workout history is not saving. Katalyst is quite the exercise hack. In 20 minutes, you get a full body workout that you can feel for days. The trainers are very professional and keep things moving. App suggestion: please make it so we can save our favorite workouts ### 5/5 — Workout Hack *2023-10-20* Katalyst is quite the exercise hack. In 20 minutes, you get a full body workout that you can feel for days. The trainers are very professional and keep things moving. App suggestion: please make it so we can save our favorite workouts ### 5/5 — Love my Katalyst *2023-10-07* I had my Katalyst for about 2 years now and it comes with me wherever I travel. As a fitness junky, I know I will get a great workout no matter where I am. Lower body and glute workouts are the best!!! ### 5/5 — Love Katalyst! *2023-08-31* This has checked so many boxes for my workout goals. In addition to my existing lifting regimen, I’ve started doing twice weekly Katalyst workouts and it has unlocked progress that would’ve taken me months or years. My knee and shoulder pain have gone away and I’m able to leverage these EMS workouts to push myself without added injury risk. The App had way more variety and capabilities then I expected. Overall, I have been very impressed and pleased with the results. ### 5/5 — You’re not going to find a more efficient work out! *2022-12-24* If you have limited time, this is the best workout you will find anywhere. This is where high-tech meets high intensity. I’ve done every kind of workout hack this is, by far, the best. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
