It wasn’t that. It was more like a sunburn that eventually dried up and peeled away. That was in September and I’m still afraid to use it again. ### 2/5 — Workouts dissapeared *2020-06-25, version 3.2.6* Not sure if its a bug but got my bionic gum yesterday had all the workouts including pro unlocked. Now today all the regular workouts are gone off the app and only pro is avaliable. ### 1/5 — Poorly designed App *2020-05-29, version 3.2.6* Like the user below, the second time I used the app, it pairs with the Bionicgym but there are no workouts. I've restarted my phone and the unit and reinstalled the app but I have zero workouts ### 1/5 — Really bad app *2020-05-29, version 3.2.6* Similar to another review, waited forever for the device and upon receiving it I found that the app experience is terrible. The biggest frustration being that no workouts show up making the app and physical device literally useless until that’s fixed. More waiting I guess. ### 1/5 — Don’t bother *2020-03-04, version 3.2.6* This was an indiegogo campaign that sounded good at first. The science works, these guys are just business idiots. It’s been over two years before I receive the actual unit. When I get it, nothing works. Keep getting cheery replies to my emails that amount to, “don’t worry, everything’s going to be all right”. Nothing is. Too much money, poor correspondence, crappy equipment, horrible customer service. Don’t bother. Stay away from this company. ### 1/5 — Poorly designed app *2020-02-20, version 3.2.6* As a backer and having paid a good amount of money for this, I’m a bit irritated at this point. The app worked fine the first time I used it. Second time, it connected but gave me zero workouts. I logged out and tried to log back in, but it won’t allow it. Reset password. Still won’t allow it. Tried to register a new account, it shows a thinking spin for 1/2 a second and doesn’t allow it. I deleted the app and reinstalled. Same thing. I can’t even login to this thing. ## Most critical reviews (10 lowest-rated) ### 1/5 — Doesn’t open *2025-03-10, version 5.0.4* The app downloaded but when I open it, the screen is all black. Can’t see anything! ### 1/5 — Not as advertised *2024-11-22* Have been using Bionic Gym for the past few months. Have tried beginner and am now on Pro 2hrs @ density 50. Both legs trembles vigorously but never a drop of sweat with heart rate hovering at 94-100 mostly. Negative changes in weight either. Nothing as advertised! Very disappointing! Currently unable it persistently disconnects even when unpaired/paired again numerous times. Deleted the app and reinstalled but same problem still exists. Instead of not working as advertised, it has become a useless brick. Searched online and found that many unfortunate buyers had same problem. Buyers beware!!! ### 1/5 — Not as advertised *2024-10-27* Have been using Bionic Gym for the past few months. Have tried beginner and am now on Pro 2hrs @ density 50. Both legs trembles vigorously but never a drop of sweat with heart rate hovering at 94-100 mostly. Negative changes in weight either. Nothing as advertised! Very disappointing! ### 1/5 — This Product Does Not Work. *2022-10-06, version 5.0.4* If you are interested in purchasing this, don’t. I wish I had read the reviews, because I would have saved myself almost $800. Customer service continues to say they will “troubleshoot” the issue but the reality is, this product is the CEO’s way of scamming people out of their money. Save your breath and save your money. Don’t say you weren’t warned. ### 1/5 — Worst company and worst return policy *2021-09-16, version 5.0.2* I was try to give it try and it didn’t work and try to return it nobody answer me and now after they told to ship it back and emailed me with refund once they will receive it now they deny the refund to me even after they never try to answer me within 22 days from purchase date what liars and crooks ### 1/5 — It won’t open *2021-09-07, version 5.0.2* The app just sits there after I checked off the boxes. ### 1/5 — Can’t use app on my iPhone *2021-06-08, version 5.0.2* Ever since the developers crashed the App back in May, I haven’t been able to log in via my iPhone 11. I’ve deleted the App many times and reloaded and nothing!! I spent $700 on a piece of technology that is rendered absolutely worthless without the App to run it. Thank God I still had my old iPhone 8, I discovered that the App works as it should on that device. But I shouldn’t have to do that, what if I didn’t have a 2nd phone/device? ### 1/5 — App is barely useable *2021-03-28, version 3.2.6* Product is great but the app is utter trash. Which in turn makes the product a huge hassle to use...soooooo please fix the garbage app that disconnects every time the wind blows ### 1/5 — Bad app and no updates *2020-12-11, version 3.2.6* This app isn’t good enough to never be updated. ### 1/5 — Doesn’t work *2020-07-12, version 3.2.6* It worked the first two weeks then gives the connection error every time now ## Most praised reviews (10 highest-rated) ### 5/5 — Best workout ever. *2020-04-29, version 3.2.6* I purchased this device a couple of years ago through crowdfunding. Mine arrived in late February this year—just in time before being on strict coronavirus lockdown for two months here in Italy. The app is still in its introductory form, but there is so much benefit from using this system just as it is! I am MORE than happy to be a part of the app’s BETA stage while the BG folks gather enough data (from us, the initial supporters) in order to iron or any hiccups along the way. Because the BG workouts are so passive, I have lost all of my “too busy” excuses to get a cardio workout. I just hook up the device, launch the app and stand / sit / lay down and let the BG do its magic. I usually plan on doing another thing I also love but don’t give enough time to do, like listen to an audio book, do online learning (I still need lots of help with speaking Italian) or watch a few guilty-pleasure TV shows. 😂 It’s incredible how two or three hours can go by without even thinking about it. Not to be too intimate, but the level to which my clothing is literally SOAKED when I finish a workout is incredible!! I have to confess I’m a kinda lazy when it comes to working out. Normally, with jogging on the treadmill I have at home, would ALWAYS try to convince myself to stop working out after 45 minutes. Even when I KNEW I could keep going. But have none of that feeling with the BG, it’s so weird! It literally bypasses my lazy gene!! Lol After two solid months my habit is firmly set--i go at it at least 5 days a week. Each week I crank up the levels higher and higher so I know my body is conditioning itself to the stimulation really well. And I even TRY now to push myself more! I have heard the BG team will be adding new workout patterns along the way—which is great for those of us who like to change it up. They've already added a few in the short time I've been using mine. There are a few Debbie & David Downers rating this app with minimal stars. But come on, when you accept to be an early adopter, you KNOW what you are signing up for. Something revolutionary in the tech world isn’t perfected at 1.0 guys. You should know that by NOW. Refinements always happen AFTER there is enough user-base feedback. We all have different brains, ages of phones, iOS versions, and levels of patience. Give them a chance. This thing is a miracle n(at least for me!!) The BG team are obviously passionate about what they do, and always appreciate it when I send questions or offer feedback. They have always taken the time to answer my questions. They’re not a huge team, and they’ve done a hell of a job to get an incredible device out onto the market. Sure, the app can still improve, but that's an easy fix to download new updates. The device itself is spot on. For once in my life I’m looking forward to my workouts!! And the best part is that my mind and body feel soooooo vibrant after sweating my arse off (literally) for a couple of EASY hours. Great job guys! Looking forward to the bright healthy and sweaty future with you all! LOL ### 4/5 — Works great! *2025-09-12, version 5.0.7* The app does exactly what it is meant to do, which is connect it to the BionicGym device and allow you to choose your workout. I have no issues connecting it, and I keep track of the estimated calories I’ve burned by taking a look at my Apple Watch after the workout, and by reviewing my Apple Fitness app. One feature that would be nice to have is to see how long I have left with the workout from my Lock Screen, which I think would be very convenient. Adding the ability to pause or stop from the Lock Screen would also be nice. ### 4/5 — Great app, just wish it had a couple more features. *2023-04-16, version 5.0.4* This app is what powers the Bionic gym electro-stimulating (my word, not theirs) pads. It works very well for that purpose, and has a really nice variety of “workouts,” but I wish it could keep a record of my “ workouts,” track “streaks”and maybe send little reminders of messages of encouragement to put the pads on and get moving. It seems most of these negative reviews are several years old. I’ve never had trouble with the app, so I’d say they’ve worked out the bugs by now. ### 4/5 — the app works *2023-01-24, version 5.0.4* i’m not sure what happened to the other reviewers but the app works fine on my iphone. i don’t have connection issues related to the app. any connection issues i have are related to the physical wires if i take large steps. four stars because it could be more user design friendly, look slicker, and have more tracking or educational features. ### 4/5 — Infancy of the product but huge potential *2021-01-16, version 3.2.6* This app is not perfect (not a lot too it at the moment beyond basic control), but the BionicGym device is game changing and there’s a lot that could be done with this app in the future. ### 4/5 — Great! *2021-01-03, version 3.2.6* The pads may lose contact w the app occasionally, but this is undeniable - heart rate up, sweating, while I work. This is a pandemic balsam for the lack of working out. I have experienced no rashes or pain (beyond what is expected from electro-muscular stim.) ### 4/5 — User friendly and simple *2020-09-22, version 3.2.6* I enjoy how easy to use this app is, however connecting to the battery unit is often an issue - especially when my partner is using his gym too. However operating the machine itself (once connected) using this app is simple and helpful which is great. ### 4/5 — Better than the last beta! *2020-01-08, version 3.2.6* In many ways, they have improved the app from the beta version however there is a significant lag when you pause or restart a workout (20-30 seconds.) Other than that, it’s pretty amazing and works like a charm! ### 3/5 — App works okay but battery indicator does not *2023-11-03, version 5.0.4* The app does what it should I suppose, but my battery indicator only ever displays two readings -100% (which it goes to after even just 3 mins of charging) and 38%. Literally just those two numbers and nothing else - so I really have no idea if I’ve got enough charge to get through a workout. It’s flashing that it’s charging now after going from 38 to 100 in 5 mins, but clearly it’s not yet at 100 because I don’t have the solid light yet. Relatively minor in the scheme of things I suppose but it drives me a bit nuts. ### 3/5 — Love the device but no Apple Health?! *2023-06-09, version 5.0.4* The device is great and I hope they update the app…but this should def have Apple Health integration! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
