Everything you need, nothing you don’t

I’m not a fan of useless hyperbole, but I think this app is everything any serious cyclist needs without any of the flashy distractions of other platforms.

As a long time Zwift user, I was concerned that this platform might prove too stale for prolonged use over the course of a full training plan. But since I’ve started using this app exclusively, I’ve noted my attitude towards training has changed. I used to justify spending money for Zwift for the racing and the virtual engagement. But realistically I would either blow a training plan trying to race up every virtual hill or get screen fatigue.

TrainerDay sits right in between the big platforms’ pricey subscription services with all the variety of a huge training library you could want and none of the diversions you might experience with another platform. Long base miles? Throw this on your iPad or smartphone and start a season of The Borgias. Intervals? Pick your poison from thousands of workouts and get started. They’re plenty engaging without slowly feeling your eyeballs turn to jelly.

As an owner of training centers for endurance athletes I’ve struggled over the past 20 years finding a simple, user friendly app that can work with our clients virtually and in studio. Ding ding! We have a winner. Alex and his team are very responsive to requests, updates and support. Keep up the great work.

Can’t open the app

I used this app a few times and now all i get when i open it is a white screen. I’ve deleted the app numerous times. I’ve erased the data and logged back in. I don’t know how to fix it, so I’m giving up. Buyer beware!!

Developer Response ,

Oh, sorry for the slow response. I see you gave us 5-stars so hopefully a later version of our app fixed your issues. Sorry again, I don't get notified by these reviews.
