The first version of geoEarl can now be downloaded from the Windows Phone Store. It doesn’t offer all the features, that the Pocket PC Geocaching Tools had, especially the GSAK-database support is not available. I see it as an addition to the official Groundspeak app to solve multi caches.

It offers the following features:

En- and Decryption

• ROT13 etc.
• Vigenère
• One Time Pad

Transformation of texts and numbers

• A=1
• Roman numbers
• ASCII
• Phone keypad
• and some more

Solver with 26 variables
