About this app

The GC Wizard is an open-source tool collection.

It was originally created to offer Geocachers as an offline tool to support them with in-field mysteries and riddles. So, the GC Wizard contains numerous tools for simple cryptography, geographic and scientific calculations as well as hundreds of sets of various symbols.

Meanwhile the project became very huge and might be practicable for many non-Geocaching issues.

Highlights

General
• Formula Solver: For handling multi stage variables
• Multi Decoder: Enter an unknown code and let several decoders and calculators interpret it in a row
• More than 200 sets of Symbol Tables: Direct decoding symbols to characters; save own encoding as an image

Works for what I need it for. Very helpful especially for beginners with geocaching and especially solving mysteries or trying to create one of your own for other cachers to find
