I do, with the Nano version. App simply doesn't work in the wild. NBD. I use the top controls. Easy to set temp, don't bother with setting time. Difficult to get it started. Maybe that "button" start - stop spot is touchy. That is my main complaint. Close behind is the over sensitivity to water level. Won't start or will stop if it's a bit low or high. Hard to see blue light indicator in sunlight.
But it doesn't keep temp well. Honestly, it's more than accurate enough at +/- 2 degrees. Just spoiled by the 0.2 degree accuracy with the joule. And the broad range of water levels accepted.
But Joule requires WiFi. If you go with Anova, just get one of the better, more expensive ones. They don't cost too much.
