### 5/5 — Tolle GPS App

*2019-01-16, version 1.8*

Ist eine perfekte App um Orte zu speichern, die keine Adresse haben oder bei der das Gelände zu groß ist. Die Koordinaten lassen sich per Hand anpassen, wenn die GOS Genauigkeit ungenügend ist. 

Teilen ist möglich, ein Klick auf die Koordinate öffnet Apple Maps für die Routenplanung. 

Richtig gute App! Danke

### 5/5 — Useful

*2017-05-22*

Useful when hiking, good for setting waypoint and favourite spots saved

### 4/5 — Eigentlich fast perfekt

*2016-11-20, version 1.7*

Ich nutze diese App sehr viel und bin auch fast 100% zufrieden, nur wäre es sehr schön wenn man eine Im/Export Funktion hätte und Fotos zu den Wegpunkten mit abspeichern könnte.

### 3/5 — Fast gut

*2016-09-25, version 1.7*

Die Navigation tut ihren Dienst, aber die Favoriten-Verwaltung ist eine Katastrophe.
Eigentlich bräuchte ich gar keine zusätzliche App, die irgend welche Adressen verwaltet. Wäre es nicht toll, wenn man aus Google Maps eine Adresse an diese App senden könnte und dann kann man diesen Punkt anpeilen?

### 5/5 — Great to log where I've been.

*2014-07-25*

I like hiking. I play with this app to log my routes for fun.  I'm sure I am not using to the full potential but this is probably legit for land or sea.  

I recommend!

### 5/5 — Nice and beautyfull

*2014-01-21, version 1.3*

This is a great Applikation.

### 5/5 — Excellent Program.

*2014-01-04*

Works as advertised.
