Could be improved

It would be nice if the temperature probe graph would stay at the top when it goes above limits instead of down to zero. This always sets off my low temp warning and it is not cold, it is actually hot. Also it would be nice if you could rotate screen and zoom, that works on the web browser, not the beta app. 3 things that would greatly improve this.

No longer a fan

We’ve been using LaCrosse Alerts Mobile for many years now. It seems like each app upgrade takes it farther from an ideal app and service. On average it takes 10-15 seconds to connect to the server to see the temperatures and other data. There is so much wasted space on each page with a drab unchangeable appearance. My only option to ‘customize’ the appearance is to upload a photo of the monitored area to fill roughly a quarter of my iPhone screen. Otherwise I get to see the sensor itself. The thermometer icon which is dynamic is small enough that changes aren’t really noticeable unless they were massive temperature swings. We’ve allowed our enhanced alert service to expire and are transitioning over to another brand. The app developers are going in the wrong direction.

Helpful app

I like this interface for the app, the information is easy to understand and flows well. The gateway was a little hard to set up but it only took a couple minutes, the sensors added easily. Everything works as it should. I wish there was an option other than buying a subscription to their notification service.
