Great app! However, could use a couple of tweaks.

The videos are great, I love the workouts and the app looks awesome.

Couple things I would recommend changing just for convenience sake: Either have the workout itself as the cover/thumbnail photo for each video or having pictures so you don’t have to wait for the video to load and go through the intro video. If you have bad service or don’t have unlimited data it can be very inconvenient because the video could take a while to load and you aren’t getting the best workout at that point. Also the timer isn’t the easiest to use because you have to scroll all the way up to pause and stop. It would be more convenient if it just stay in place on the screen even after scrolling down or up.

Anyway, great workouts, you look great and I plan to get to the same level!


Better but still more to go

Content-wise this is my favorite app. Chris Heria is great.

However, the app itself, though it has improved, can get better. I have a list of suggestions.

1. Reduce the length of in-workout exercise videos, only focus on the movement - not the intro or just talking. People want to focus on the workout, not waste time on watching videos.

2. Make each thumbnail for the video specific to the exercise. When it’s just a general thumbnail it’s confusing.

3. It’s very hard to do the workout with the basic timer. Make a rest and an in-set timer. Also have a counter for the rounds.

4. Make even more basic programs/progressions. The beginner program is already hard for the majority of the population. More users will sign up with an easier entry. E.g. the expectation to do 12 leg raises right off the bat.

5. Make the app payable by subscription on Apple. The website looks sketchy and prevented me from buying twice.

6. Basically, throw all ThenX content into a Mad Barz style app.

I’m looking forward to staying on board with ThenX as the app gets better!


Needs to be more beginner friendly

I’m a total beginner to calisthenics and I have no equipment. I was looking forward to this app but when I got to the beginner section I scroll through and find pull ups and tucked Lsits. Idk about other beginners but I can’t do any of that. So instead of getting into the workout I have to go find modified versions of those exercises so that I can participate to the best of my ability. I would have like to see a more beginner program that is still challenging and will build strength and muscle for these workouts but it just seems like it’s tailored to people that can already do these. I’ll still use it but I wish they thought more of beginners who literally just started calisthenics.
