Switched from zwift to (paid) TD lately. I like it very much except for one serious issue. The app keeps getting progressively slower during a workout. Eventually, at the end of a one-hour workout, 1 second in the app is approx 2 seconds in real life… I timed it with my phone. I tried the app on two different iPads (1 quite new) and on an iPhone 13, all the same. Due to this issue, the total workout time in the app and also in strava is way off too. I use an Elite Direto trainer and a polar h10 HR strap btw.
We occasionally have users with slow downs like this but usually a phone restart fixes it but seems less likely if you experience it on multiple devices. It also happens more on phones low on memory or older or slower. Are you doing really long workouts? Can you send a link to one of your completed activites?
Oh, I think I understand what the problem is. It has to do with how your specific trainer handles ramps and how we send updates (every 1-second during a ramped interval). Zwift only sends updates every 5-seconds for example (As I understand it).
This is a problem that has plagued us for a while but we keep slowly fixing it, but you might be able to help us fix it once and for all. What trainer do you have?
You could verify this by doing the same workout with steps instead of ramps or flat intervals.
Yes, I understand. I was going to guess you had an Elite. It seems Elite trainers are more temperamamental than most other trainers. If you send updates too quickly they get over loaded and start throwing errors. Let me think about this a bit and get back to you.
I fully understand. Training needs to be as predictable as possible. If you contact me via email and you paid from our website. I can refund your money. We are small and random people have problems from time to time and we do our best to resolve them. You can read but strange problems happen to certain people on the bigger old platforms as well. You just were unlucky here.
Curious, As far as I understand how these sort of things work, sending updates every sec vs every x seconds will only confuse the trainer, but looking at the links @matthijskox shared(thanks!), it seems like the trainer is functioning per the power profile/workout. Doesn’t look like it’s losing it’s step or such.
No much more, at the end of the workout it is like 1s in app is 2s in real life. But it is progressive, so non-existant at the beginning of the workout and then gets worse.
Not sure if this is related to your issue or not but here goes:
I also have the Elite Direto and use the Iphone 3-year old phone (iPhone 11) or PC, with Zwift or TD erg mode workouts.
The Direto is a physically solid and awesome bang-for-buck smart trainer, at its price point.
However, it is EXTREMELY slow to react to erg mode changes - regardless of which app I am using. This is a known issue and prevalent on the Elite forums.
Bought a Wahoo Kicker on special in December. No more frustrating erg mode delay issues.
