********************************************** NEW: Encode plain text into symbol language NEW: Wherigo Reverse solver ********************************************** CacheToolBox is an ideal tool for all ambitious geocachers and hikers. The app offers conversions for the Swissgrid coordinate system in Switzerland and for various WGS84 formats. Furthermore, the typed coordinates or the current location can be displayed on the map. The map needs an internet connection. In addition, the app offers various tools such as ASCII, numbers to letters, text to numbers, rotation, bearing and distance between two coordinates, prime numbers checker, waypoint projection with current position, Roman numerals, temperature units, number systems, Wherigo Reverse solver, tool for Multi-Cache with calculator. The big collection of interactive code tables continues to be an important part of CacheToolBox. Outdoors, you can decode the encrypted messages smartly with the "symbol keyboards" which were displayed in plain text without any Internet connection. CacheToolBox now also offers the opposite way: simple encryption of plain text by keyboard in symbolic characters! There are currently 116 code tables available. In future, more tables and tools will follow in free updates!
