The GC Wizard is an open-source tool collection for Android and iOS. There is also an alpha version of a Web View.
It was originally created to offer Geocachers an offline tool to support them with in-field mysteries and riddles. So, the GC Wizard contains numerous tools for simple cryptography, geodetic 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.

Based on Flutter/Dart.
- There are so many great Geocaches out there. We had so much fun with them. With the GC Wizard, we want to give something back to the community. We may not make such great Geocaches, but hopefully a great supporting tool.
- The GC Wizard will always be free for everybody.
- With making this project open-source we want to invite all the great GC tool providers to share their knowledge and algorithms. Nobody should need to build a ROT-13 tool or whatever from scratch anymore. Somebody already did it.
