Geocaching is a worldwide game of hiding and seeking treasure.
A multi-cache involves two or more locations. Clues guide the geocacher from location to location. Sometimes these clues involve a puzzle, some calculations (e.g. on text or using roman numbers) or projecting a new waypoint using distances and bearings. Sometimes the calculations are easy, but this toolkit can help when calculations become tedious while out there in the field.

This geocaching toolkit can help you using the following features:

Waypoint Calculations
- Conversion of degrees, minutes and seconds to other formats
- Conversion between WGS84 and UTM coordinates
- For my Dutch friends the RD coordinates are included
- Also the Swiss grid is supported
- Show the entered Latitude/Longitude using the iPhone map application
- Project a waypoint by specifying distance and bearing
- Calculate distance and bearing between two waypoints
- Intersect two lines using two waypoints and bearings
- Intersect two circles using two waypoints and distances

Text Calculations
- Calculate the sum of the character values in one or more words
- Choose between a=1, b=2 etc., the inverse a=26, b=25 etc. or the phonepad abc=2, def=3 etc.
- Also calculate the sum of all digits of the result
- Repeat summation of digits until 1 digit remains

Hint decryption
- Decrypt encrypted hint text to plain text

Roman numbers
- Convert between roman numbers and decimal values and vice versa

A good start

Insp Gadget 113

Interesting little app. I think it's a great start. I would love to see this expanded to include some way to help me when locating multi caches, such as a way to store, hints, clues etc, all under the GC name maybe?


Great help on the hunt


I like this app, since it is so useful on the hunt for a cache and I use it to save time. Another feature I would like to see is a MILS converter. I have encountered Mils a few times and needed to convert Mils to degrees and back.

Somewhat usefull!!!


Really good for projection caches, haven't found much use for it otherwise.
