Hi David,
I installed this APP and I can only confirm that ouside of the UK it doesn’t give the locator grid, just the Lat&Long. Regarding the height, I’ve noticed big differences with my phone always in the same place on top of my shack desk. It measured 505m on the first time, then 406m, then 465m, now it’s reading 442m… It’s OK to have a rough idea but definitely not too accurate. I guess it’s estimating the height a.s.l. based on the barometric pressure, hence the different readings in different moments of the day or in different days.
Finally, the compass doesn’t move at all in my phone and I don’t know why. It could be my basic phone’s fault…
I had another free APP previously installed and it gives me 6 digits QTH locator, Lat $ Long coordinates, Altitude in meters and feet, plus date and time. It’s name is Easy QTH Locator by US1PM Boris.
Some time ago I found an APP able to give a 10 digits QTH Locator (extremely accurate positioning). I had it installed in one phone that got unfortunately broken, so it was retired and replaced. I can’t find that APP anymore on Play Store. Shame…
I wrote about it in this thread:
