Statistics on App and Site "Error: "NaN number in JSON write"
As you see in the screenshot, I get this when I try to view statistics in the app. Also, if I open the gymhero.me dashboard website the volume and other things only list ‘NaN’. However, the Fitty.co website shows all my recent workouts and statistics.
Uff, that’s odd, sorry about that. Does this happen since you added the last workout? If so, could you share the url of that workout privately with me so I can have a look if something in that workout’s data is mixed up, causing that NaN error (this stands for “not a number”)?
I actually had a line in one of my workouts where I forgot the rep #, and that made the NaN error be displayed.
Weird! The line looked like the image attached,
That resolved all the issues. So weird! Don’t leave a line blank!

Wow, we really have to fix this, thanks for finding that bug! As a thank you, we’d like to give you a promo code for Gym Hero Pro, for you and a friend. DM me if you want it (Apple invalidates them unless they’re redeemed within the first two weeks, unfortunately)
