I recently starting playing around with a few Topographical map apps for my phone and found “All-in-one Offline Maps +” to be super useful. It allows you to save sections offline, so there’s no need for cellular signal. We used it recently in Cederberg and it was very helpful in confirming our location on the map when we weren’t 100% sure, or helping us navigate back to our campsite through the rocky maze on top of Groot Krakadouw. Unfortunately it looks like it’s only available for Android users.
Anybody else have good experiences with other apps for offline navigation?
