Ratings and reviews

Disappointed in the gps changes. the original "extended" UI was simple yet informative. I'd been using the app for years - even purchased it recently to show my support. also there seems to be a bug in the altitude. the flight I'm on is at 5000m, but the app is showing 5000ft. The aircraft is using barometric altitude, but that difference is too large to be due to that. there's almost certainly a unit conversion bug in the app. Rating 5 stars because of the past, rn it wouldn't be 5 stars.

I've used this app on every phone I've owned for the last decade. It's always been reliable. Now it suddenly changed and the graphs are so small that they are pointless. I can't do anything to change the size and if I flip it to landscape mode, the graph disappears entirely. I uninstalled, then reinstalled, cleared the cash and changed every display setting on my phone, with no luck. Please fix it.

Impressive light, sound (dB meter), magnetometers, satelite info, g-sensor, A fast spectrum analyzer with many bands . Well thought out and I don't see ads on the version I have. I would never EVER click on one. There's many other features using the internal sensors of your cell phone which is more than you would realize...with a working Compass, angle detectors, 3axis magnetic fields and so many others. It must have taken a long time to build this. Thanks
