### 5/5 — Rob

Hi Dan, I’m having trouble downloading your app. I had it a while ago but it vanished. I have found it, without doubt, the best app for my use. I’m unable to find the pay-for or download options. Regards, Rob

Die App tut was sie soll und ist sehr leicht zu bedienen. So muss das sein. 👍🏻 Für mich als Soldat sehr interessant ist das MGRS, Top.

Не качайте это приложение, оплатил его и теперь весит недель в ожидании. Нимагу ничего скачать с эпстора теперь.

### 5/5 — Wilderness user

*2015-08-28, version 1.3.0*

Works well, saves battery and works off line if you browse the intended area of travel ahead of time. Distance measure is hard understand, but GPS  and compass function works great

I love it.
