What have you done? This app performed perfectly for me with by Zwift trainer and today I opened it and it completely changed. The interface is different and doesn't work. I choose 45 minute workouts and it switches to 60 on its own. I start a workout and it doesn't make it one minute before it crashes. I rebooted, I restarted. Four crashes and I give up. It's absolutely trash now, Please revert to the old app until you can make this one work reliably.

Sorry, Android 15 required a lot of changes that we finally did them and it is causing some users issues. We are working through every issue we can find. For most users it is now working fine. It might be a few more days before we can address every device issue that is included. Contact me at support@trainerday.com and I can help.

Background issues: works great in the foreground, but if you want to watch a show on the same device while exercising you are out of luck. I use a Galaxy 25 with latest android. about a week ago, when bringing Netflix to foreground the trainerday would automatically pause and disengage erg. this week at least it keeps running, but erg power changes don't happen per workout chart.

Hi, got to android settings/apps/trainerday and turn on physical activiity. Or uninstall/re-install and it should ask you.

Worked great with my Yosuda semismart cycling trainer. Got connected effortlessly, and picks up RPM and Watts and reports time. I'm a woman in my mid-60s with knee cartilage damage (chondromalacia) and wanted to use the machine for healing. Being totally unfamiliar with these apps it took time to realize that I needed to set FTP but then I saw afterwards that my efforts followed the workout profiles. I plan to add HIIT back in. Thanks for having an app that works with an inexpensive trainer!
