Prusa App and Belt Tuner

Hello, 

I'm woundering about the prusa app and the so called build in belt tuner. As fas as I can see the app offers a web link to "https://belt.connect.prusa3d.com/". Let me ask prusa and the community why they talk about a build in belt tuner?. My CO ist in our cellar, and there is a terrible up to no phone / network connection. I can deside to move the printer upstairs od taking another app. I did the second, which is has a really build in belt tuner. The last app did have a really build in tuner, it worked offline and was fine. Now we got a "improvement" which is just a lie. 

I'm really dissapointed  about prusa and their understanding of build in features. 

Let me ask the community. Is there a change to get the belt tuner function as a really working offline tool like it was before?

RE:

Hint, the newest "release candidate" firmware has an excellent belt tuning utility that excites belt oscillations via the steppers and uses the LED bar as a stroboscope. Flashing the firmware is a matter of seconds, so is reverting to the original one (if you go prepared with two USB sticks). You may need to recalibrate, which you'll want to do anyway after mechanical changes.

The new tuner is very good, compared to the old one.
