    Update Sept 2021. It is less rigid to adjust schedules or change the order. You select the day in the program and just deal with the reminders. You can record the bands used. Would be nice to be able to take a manual note and also view the bands used last week. Still would be nice to swap in variations that Undersun has posted on youtube. I'm using the program to strengthen after surgery and really like it. Feels like the contrator selected for the app way overpromised and underdelivered.
  • Good app! Feb 17, 2021

    I love that they decided to make an app for these workouts. Its nice to be able to track the TA2 program I’m doing. Also the bands are a killer workout. My only feedback would be that the app needs a little more tweaks - specifically in the completed workout section it lists the workouts you’ve completed then say “number of workouts you has completed” - minor grammatical error but it makes the app look cheap. Also the timer in between workout sets seems to stall when you lock your phone, and it doesn’t make any sort of alert sound (both of which are pretty standard feature for any workout app with a timer). Overall I like the app a lot!

    First, great job and I have trained fir 45 years, never learning much from trainors or online programs. After using 4 months and seeing great results, it would be womderful to me if: More diverse exercises were offered (I would pay more for an advanced program). I can go beyond 45 minutes and 2-4 optionsl exercises would motivate me. E.g simulating leg extensions and curls which remain effective, as well as other calf raise options that burn. Link to sports and/or bodybuilding was explained further. How to handle pains such as common rotator cuff or hamstrings to not prevent further training? Subordinate exercises to around most common injuries. Why no optionsl bars/barbell and handles for combination with classic lifting we have all experienced and found useful? Other improvements related to tracking past performance on exercises and print output options for refferal. But a greac app and a great teacher! Congrats!

    There is no ability to change your workout times once set. A little inconvenient but not a deal breaker. All the articles have broken links which make it harder to find the tips etc.

    I am currently unable to log in after entering my details, I constantly receive a HTTP 500 error message. Tried uninstalling and reinstalling, still receive the same error. Can this be looked into please? UPDATED REVIEW: The app now works and is a really great experience. The support from Undersun Fitness is outstanding. I highly recommend the app.
  • Well done! Feb 14, 2021

    The app is very useful, works fast and provides all needed features, however it would be cool to add synchronization with Apple Watch, so I could select results from my watch, would be very handy! Thanks :)

    Awful...no license key. Multiple attempts to Activate. Once activated shows no program purchased. Keep saving my gender to Male because it reverts to female. Getting a complex over that...🤨🤔 BUGGY and not ready for Prime Time. Not a good impression and have Put in for a REFUND to Amazon. UPDATE: Support has been very responsive. I have access to the program and I have cancelled the refund request.
  • Calendar Manipulation Mar 11, 2021

    By Rooster Magillicutty
    When I see calendar, I’d like to be able to select the day and enter the specific time of my workout (like I initially did when I started the program). It flows well but could use some more Beta on use and inclusions.
  • Please update scheduling Sep 13, 2021

    I have updated my workout schedule several times and the alerts are tied to the specific time you download the app, not what the schedule you have set is Great app otherwise!
  • Stats tracking May 24, 2021

    By Thee_Tamer
    The TA2 workouts are very effective but can be monotonous. Even when more modules are added the estimated time to complete stays at 30min. The mood tracker stays at ‘discomforting’ even though I have only logged ‘distressing’. Looking forward the the apps continued development.

    Within a week of purchasing this, I got the HTTP 500 error. The support section on the website doesn't work well either. I tried sending my comment but it just kept refreshing the page instead of sending it. So I just sent the email address provided below an email. If the app is down, make the content available offline. If you want add the copyright protection so it cannot be recorded but do not inconvenience the user as well.
  • Great program, app needs a lot of work Jul 13, 2021

    By Billy1234567890qwerty
    Update: changing from two stars to one… I was able to get back in but now, less than two weeks later, the app is crashing again. What’s the point of having this when it’s pretty much worthless? You need to go back to using the web-based tracking since your app is terrible. Great program, I hope they don’t take program off their website until the app actually works every time. I was going to hold off on writing a review until developers had a chance to work the bugs out of the app but I can’t even get in the app right now so today is the say. The developers need to come up with a way to see the previous workout while in the current workout. I have an idea of what bands I have been using but have to screenshot the previous workout if I want to continue to build on the previous week. I get an error every time I try to get into a workout now. I deleted and reinstalled the app and same issue. I guess I will use the website and I won’t be able to track progress. Please fix your app, won’t be spending any more on Undersun products until the products I have paid for actual work.

    So far 1 star. I'll update this if it gets fixed. I purchased the bundle because it was the only option I saw on the website. (Already have bands) but anyway. Got an email to download the app and submit my program code to access the program and I'm hit with "This code is not found" So basically paid for a bundle and didn't get the program but the bands that I already have are on the way. 🤔

    Haven't had that app work right once since I got it 6 months ago. The workouts were great when I could get it to work, but I had to start fresh every time as if I hadn't been doing the workout for months. Also had to log out and log back in 3 to 4 times before it would even acknowledge that I had the subscription. over all love the bands and workouts were solid, if the app would've worked I would keep using them but taking up a 3rd of my workout time messing with an app isn't going to happen

    The workout routines are great. The app is terrible. Videos don't play half the time, some of the excercises are missing the resistance band options for tracking. And now I can't even log in on my phone or tablet cause it says I have no internet connection and to check it and try again. Even when I'm on my wifi or on 5G. Recommend getting monthly subscription, writing down the routines. Then immediately canceling

    I can log in on the website and get my workouts, but when I go to log in on the app, it tells me my password is not valid and then that I have never had an account with my email. I go to the signup page and put all my info in (even though I’m already signed up) and the “sign up” button is not even clickable. Not sure what the deal is here but hopefully I can access the workouts after they close down the website!

    Could never stream Spotify playlist,always states Undersun fitness is connecting,but never does. Notifications is a pain in the butt...if you want to work out in pm as compared to am...it sends a notification saying you missed a workout. No lead way for working out at different times. I'm a male,I'm able to change/edit my weight,but after trying 100 times to change to male...app still states I'm a female😆. Same goes for trying to edit a change in resistance bands. Very disappointed ☹️
  • Exercises are good, app is terrible Mar 15, 2021

    By Obbobbo
    Rarely am I this disappointed in the functionality of an app. The workouts in the app are good. The calendar aspect of the app is terrible. Even when I select the day of the week I want my exercises to be on, it cannot understand it. I wanted my workouts to start on Mondays and the app keeps tracking Sunday’s instead. I started exercise and it doesn’t record it. It’s pretty annoying.
  • Great content but the app is challenged Jul 24, 2021

    By Jason-Making-Progress
    Big fan of the content that James Grage produces. It’s professionally done and even intermediate lifters will benefit from his work. That said, the app needs help. It crashes too often and you have to “renew your subscription” in order to get the app to work again. Use the app to learn about a great training program but expect challenges to the app until it is fixed by developers.

    Spotify integration doesn't work, videos don't have any buffering for slow wifi connections, no offline mode and the display won't stay on while the program is running, I need to manually change the sleep setting to 30min so that I can even start the program. The exercises are great but the app really hurts the experience. The content should be available elsewhere

    This is is a great app. Having the routine laid out for you with video instruction is huge. However, major room for improvement. Below are just a few. Offline support, need the ability to use the app if the internet is spotty. Audio tones when the rest time is done. Ability to see the band(s) that was used for the exact same exercise, the last time it was performed. Need notes, for example, if I use a band that was too light, or heavy last time More band combination options

    The workout program is great but the app has a few minor issues. I can't put in my proper gender (male) because it defaults back to female. I can't put in my repair for every exercise to track ertain progresses.

    In month 1, shoulder day, the pictures of the single arm shoulder press exercise (1st exercise) are worng and showing another one. Also the rescheduling feature is limited and confusing and needs to be totally reimagined. The app is good, but there is still room for such improvements.

  • Shouldn’t be that hard to QC an app Nov 21, 2020

    By EZRob
    Overall the app is good but whoever checked it prior to release should be fired. They have the wrong pics for some exercises and the order of the exercises is in question too. Why would you do calf raises first snd squats last on leg day?!? Come on!!! Fix those few things snd you have a great product.

    Spotify won't conect to the app so the app asks me to download Spotify but I have it already. The app won't let me start a work out with this error! I've waited 2 months for this to be sorted now! some of the exercises are not right for the videos they are connected to. this app is terrible, if you re-done all the videos and put some money behind fixing or even making a new app this could be good. would like new exercise programme, rather then having to redo the programme as you become advance

    Seems like a good program I bought the 5 bands pack then I realized when I down loaded the app you need to buy the program I fell like it’s pretty retarted that you buy the bands but then you also have to buy the program i fell it should be free to the people that bought the bands because then you also have to buy the program
  • Beta App is -5 star Aug 10, 2021

    By Barbarey Coast
    The customer service is a -10, they never address the issues I bring up because they provide incomplete answers. I bought the bands with the year subscription on the App. The workout videos are great, but the App is extremely disappointing. I will not be renewing after my subscription expires.
