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.

ReceptionRating · Positive reviews · Number of ratings

what3words holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: what3words has 44K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Geocaching Toolkit iGCT Pro's written reviews are positive against 55% of what3words's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Geocaching Toolkit iGCT Pro ships an update every 4 months, what3words weekly. The most recent releases landed on November 6, 2026 and November 8, 2026 respectively.
