  • Good app! Feb 17, 2021

    By Winnerwinner
    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!
  • 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.

    The idea of working out using bands and the exercise routine under the sun provide is good. However the app, as stated by other reviewers, is not ready and shouldnt have been released to the market. Its laggy, it cuts out in the middle of the workout. First few weeks of workouts appear to be the exact same excercise routine following same excercise order. Worst of all, I have contacted costumer support and it doesn't seem like they have any interest to respond. I'm still a fan of Jame tho. Sad

    I’ve been using the app since the initial release. It has come a long way since day one. It was use full, but it still had some sticking points. From a UI perspective, it’s decent...but there is still a lot that can be done to improve the app further. Like: 1) Separating the month/day/workout look. It’s a bit confusing looking and combing through a list view. 2) Hopefully the developer and/or the writers would keep up with the article section. Some of it seems to be recycled from the Undersun website. 3) Need another quality control run on ALL the content. Making sure every is matching up to what it’s supposed to. 4) Would like to have a content download option for when we don’t have internet connection. And I think this is the most important thing for the next update. I think if all the stuff can done within the next few updates, this app would totally be rockin!!

    If I could give this app zero stars I would. Constant error messages. Can't even start the first workout. App shows promise but at this time it is a waste of money. Please fix ASAP as I would like to start the workouts. Update (3/10/21): Issue was fixed and I was able to start the workout program. Thank you so much for the prompt response. Y'all rock!

    App's getting better, at least it doesn't crash anymore/delete the program from my account. The new BS though is with the fact that if I exit the app for like 5 minutes, it resets the progress to the beginning of the workout. Makes no sense, it's super inconsistent too because sometimes it'll reset after 5 minutes and other times, it'll be fine for an hour. This really messes with the total active workout time stat so it should get fixed.

  • Need to see previous info May 2, 2021

    By Clutch5000
    When I get to the 2,3,4th time through the workouts, I would like to be able to see what strength band I was using the time before. The only way now is to look before starting and hopefully memorize what it was. This is quite hard to do while focusing on the current exercise.

    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 :)
  • A very nice app that demonstrates the movements, has a rest timer, and workout tracker Nov 10, 2020

    By ajcreighbaum
    This app would get 5 stars from me except you cannot edit your reps or resistance band type used after you submit what you just did for that set. The way the app is designed is that there is a scroll-like function that allows for you to scroll and select the amount of reps you did and then also scroll to select your resistance band (weight) used. This is great since it tracks it for you on what is considered a scorecard. The downfall is I accidentally selected the wrong band a couple of times and could not edit that. After the workout was over I figured I could adjust it on my scorecard....again could not. The easiest solution would be of course for me to not mess up. However, the 1 minute ‘rest’ timer starts after you put in the information for your successful set....so I wanted to quickly get the information put in to keep my workout rolling. If there was an edit feature put in so this could be fixed during the rest period, this app would have 5 stars.

  • 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.
  • Can’t get past first page Feb 7, 2021

    By Stin20
    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!

    The bands are good quality and James gives great instructions on how to use them. However, the app itself is not ready for release to the public. There are two Thursdays in a week? C'mon man. Some videos will not stop playing in a loop and others will not play unless you restart the app. It's terrible at tracking your workouts which I thought was the point of having the app. Just watch the videos on youtube. The app is a waste of money. James seems like a guy with higher standards than this.

    I've had to massively downgrade my raring for this app. Rather than getting better it has got worse. I am no longer able to access the programmes i have paid for, my profile details have disappeared. A horrible user experience all around, this on top of annoying buffering issues with the videos.

    Why am I paying full price to be a BETA tester for your app!? Today I cannot access any of the workouts on my phone, tablet or computer on account of what appears to be a java script error. If you purchase from the Canadian website you do not have access to the online training because it only acknowledges purchases from the USA website. Getting close to requesting a refund because I am feeling like I paid full price for something that was not ready for release and now I cant even use because access is an issue.

    I signed up and created my account for their TA2 build program on my computer, but their app doesn't have my account email Registered. It says I need to create a new account. The website is encouraging people to use the app saying the accounts will no longer be accessable on the site. So, why aren't they integrating the email and sigh up data into the app?? Are they trying to save money by making us re-create an account on the app rather than have their programmers integrate the data? WTH🤨

    Great exercises but app is trash. Can't edit workouts to change old numbers, forced to start on day you don't want. Slider for days to exercise is out of since. If app crashes or closes accidentally, you can't continue from where you left off, forces you to start over. Trash!

  • So Frustrated!! Feb 3, 2021

    By Mrs. Smith86
    I really want to like this program and app BUT it is so frustrating! I had the program bodyshock prior to the app release. I was told I’d be informed of when I could get into the app with my program and was never contacted again. I finally get into the app and I cannot seem to get past the first group of workouts. When it changes to the first HIIT section, the video just spins and spins. So, I went to my laptop and punched in my information to do the workout from the website. Nope, the message stated my information was incorrect. So, now I have no access to the program at all. Speaking of the program, I’m not crazy about these workouts either. It’s so repetitive and no variation to the exercises. After all that.. I still want this thing to work and get through this program!! I needed something for at home and still feel like I was getting a gym style workout.

  • Feb 10, 2021

    By Brian Maschue
    Would be fine but right now it is not useful for tracking progression because the band size you select during your workout is not the same as what shows up in the workout log history. Fix this and it will be fine. Edit: The problem with the app not recording the right bands has been fixed. This really is a great app now and I am even more motivated to not miss a single workout. Thanks for fixing the problem. Upgrading to 5 stars.

    I wanted to do a strength workout to offset the loss of muscle with age. Working with resistance bands is great because they don't take up space and I can carry them while traveling. The bands are good quality and a good range of strengths. The Undersun program seems very well-rounded to me and motivating. I am really happy with my decision to do this. O was following the program on the website, but using the app has more features.

    It provides access to the programs without the hassel of the website which is great. The workout you want to do is easily selected. The negative is that it trys to schedule and track your programs. It is very rigid with no room to adjust schedules, change the order, or take notes if needed. Additionally would be nice to swap in variations that Undersun has posted on youtube. As far as the Undersun team, Jennifer was very helpful when I had issues migrating to the app.

    The Undersun team is absolutely legendary. The product (bands) is out of this world. The programs are fantastically well put together. The app is brand new and some bugs are to be expected. But overall, a VERY welcome addition to the Undersun TA2 arsenal. Just finished my first workout within the app (Build) and did notice a little bug. Bug: The band size I selected during my workouts wasn't what is reported in the "workout card".
  • Needs work Nov 16, 2020

    By Nicotinamida
    Overall. Great idea. Been wanting an app since Undersun released the first programs. I only wish that there was a Text version of the workouts. With no video. Cause. I find it very annoying that when you finish a set the video of the exercise starts playing and my music pauses. I’ve done these workouts more than twice. So there is no need for videos. Just put the Sets with the amount of reps. And a box where you can select and edit the amount of reps performed and which band used. How it is now its overly complicated and annoying. For me of course.

    The idea of working out using bands and the exercise routine under the sun provide is good. However the app, as stated by other reviewers, is not ready and shouldnt have been released to the market. Its laggy, it cuts out in the middle of the workout. First few weeks of workouts appear to be the exact same excercise routine following same excercise order. Worst of all, I have contacted costumer support and it doesn't seem like they have any interest to respond. I'm still a fan of Jame tho. Sad

    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.

    Trying to reach the customer service team for access to my new account. The code to unlock the training app is not working. Although I don't have the bands yet, I want to follow the workout & review while my shipment arrives. I would like to try the workouts with the current bands I do have since I have paid for the access, today. Thank You.

    UPDATE: 2/8/21-Had to be sent an activation code in order to access my program on the app. Will update again after I've had a chance to use/play with the app. FIRST: I can't even access the program that I've already paid for on this app. So, at this point it's worthless. Fix these kinks out guys before you close the online platform or you're gonna' have a lot of pissed off customers if they have no other way to access programs they've already paid for.
