### 1/5 — Can’t sign in

*2023-07-29, version 1.5.6*

I had purchased program back in 2020. Order#36686. Now I try to sign in, it says incorrect password. I tried to reset password, I don’t get an email link to reset it. I don’t even know if you guys deleted my account coz it was so old.

### 2/5 — Great workout program, the app is terrible…

*2023-07-18*

The workout program is great, but the app is down regularly which is extremely frustrating. They completely changed the format of the app a few months back but unfortunately did not seem to fix any of the bugs. It’s almost always a waiting game (sometimes taking days) to get access back to your workout program.

### 1/5 — It’s now even worse than it was before

*2023-05-23*

They took whatever tiny bits of this app that were working and ruined them as well. You know have to skip through each video to reach the exercise you’re looking for. Calendar completely useless. A real shame.

**Developer response:** Hi Royherm. We truly appreciate your patience with us as we do our best to provide you with a great App you'll be happy to use. Our App is in Beta phase and still has a few kinks to work out before it is officially ready to use as a tool to help you stay on track with your fitness journey.

### 1/5 — Great program, terrible app

*2023-03-26, version 1.5.5*

The app used to be useful, there were some issues but you could make your way through a workout. I’m not sure why Undersun took such a huge step backwards with this app but you can no longer track weight (band size,) sets, or reps.it’s mind boggling how a company can take something somewhat useful and get rid of most of the features. Shaking my head at how bad this thing is as I delete the app and move on to something different.

### 5/5 — So good 😍

*2023-03-23*

So good :)

### 2/5 — Was good, now terrible. Chase is still the man.

*2023-02-27, version 1.5.5*

Chase, the customer support guy and Under the Sun is fantastic. Give that man a raise.

What was a functional workout tracker and instructional video at the start of each exercise is no longer available. It’s just a long string of what’s YouTube videos. It’s a shame as the content is good. There was a note in the Facebook group that they intend to restore some of the functionality by Spring 2023, but they’re changes too slowly to keep customers happy.

### 1/5 — Old version better

*2023-02-08*

This version has great video quality but that’s where it stops. They got rid of the workout log, and videos that were attached to each exercise. Now the video is continuous and you have to manually pause as you progress through each exercise. Disappointing choice by Undersun.

### 1/5 — Terrible upgrade

*2023-01-29*

You guys had an amazing app before . This new app is absolutely terrible . The videos don’t even work! I lost all my prior content that I paid for .. what gives

For some reason every single arm day video doesn’t play

### 2/5 — Was great not so much

*2023-01-23*

It has been in here since I have used this my app I wanted to use it again. It was great for my weight loss and strength training. I do not like this current app, you can’t track your set or reps. This is a down grade from how it used to be! The workouts them selves are great but the deliver could be better! Customer services has always been great for me so no complaints there.

### 5/5 — Very satisfied

*2023-01-23*

I love the convenience of band workouts - especially when I am traveling. Finding a gym to workout or competing for use of the limited facilities in motels is frustrating. I decided to try using bands but first wanted to find a complete workout using bands. I found a number of individual exercises online but wanted a complete workout from one site. That is when I discovered the TA2 program. 

I have been using TA2 for 3 months and find it efficient and effective. The program is a total body workout spread over 5 days with 2 days test each week and has 3 cycles that are each 4 weeks long. The video demonstrations are clear, concise, and helpful. You can use any brand of band but the Undersun bands are well-made so I purchased those.

I reached out to Undersun on two occasions when I ran into a problem accessing the program - a password issue on both occasions. Chase responded within 24 hours both times and the issues were resolved quickly.

In short, this is a good band exercise program, good bands, helpful videos, and great customer service.
