The iGCT PRO app is a toolkit that focuses on typical tasks performed during geocaching. Tasks like making a projection from a waypoint, determining a new waypoint using two other waypoints, determining the distance to these waypoints, calculating the value of a Roman numeral, and averaging waypoints are examples of what the toolkit can accomplish.

Imagine it’s lovely weather and you are walking in a beautiful surrounding. Walking with an intention, because you are geocaching and searching for caches.

Picture you are at waypoint 3 of a multi cache and you’re asked to go to waypoint 4, which is 300 meter from this waypoint and 700 meter from the previous waypoint. Now what? Go home? Imagine you have a skilful toolkit with you to find your way. Imagine you have iGCT PRO, because you want to be ready for all these kind of challenges.
