Another app in the quiver for indoor riding

I used to use a Tacx Bushido trainer along with the supported videos. Then I used it with separate workout videos. This year I upgraded my trainer to a Cycleops Hammer. I joined Zwift. It’s nice but its zone based for the workouts and I decided to look around for another way to use the Hammer.
I did t see any review on this ap mention a trainer other than the bkool but I decided to try it anyhow.
This ap is compatible with the Cycleops Hammer trainer. It found it immediately and I have done some quick test rides and everything worked flawlessly between the ap and the Hammer.
Now I have another arrow in my quiver of training software. All I have to do now is find an ap that will allow me to manually control the resistance levels in grades for the Hammer and I will have my training desires all set up.
This ap is a definite plus to have.

My go to app for indoor training

I started back riding seriously 6 months ago. Armed with a new carbon bike and a tacx new smart trainer I set out to test every app I could find for use indoors. After trying over a dozen apps I find I consistently seem to log more time per ride on this than any other app. It just seems to keep me riding more than the others without getting bored. I also find the ride feels more realistic than some others as transitions from flat to a grade are gradual and smooth and effort is consistent with what I feel outside for similar effort and grade. I have also to give Mike props for his support. I have emailed him many times with questions and although he doesn’t know me from Adam, he always responded promptly and with courtesy. Overall a great app with a rapidly increasing library of rides. Will definitely be my go to this winter season.

Using to train for Triathlon

Really like this app. I use with a Wahoo Kickr Snap for my tri training now that the weather is getting rough in CT. The videos have really good quality and are a good mix of circuits, mountains and flat courses (mostly in Australia).
I really like that most videos are curated as I found the ones on Kinomap poor. Also i feel very good responsiveness when pushing hard on hills/sprints which for me is key for realism.
This is not a game like Zwift (where you ride with other users) or has a lot of structured workouts like Sufferfest (I also use both) but for me it definitely helps to “ride” a video as it helps killing time during long sessions. Sufferfest has videos but you just watch them while doing your structured workout.
As mentioned by other reviewer I hope that they keep adding high quality videos to the existing library.
