I’ve been using Neongeo by Can-o-Worms for the past four months and it’s quickly become my tool of choice for geocaching in the suburbs.
It was the first Android app to take advantage of the Geocaching Live API, released by Groundspeak in mid-2011, and at less than half of the price of the Groundspeak app (AU$4.26), it’s a winner in my view.
The developer Mikko Sarvela from Helsinki is quite responsive to bug reports and feature requests, and although the updates were at one stage occurring almost everytime I switched my phone on, it’s slowed down to a more acceptable level.
