## Description

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

For even more functionality, the more comprehensive app iGCT PRO is available in the App Store.

## Review summary

Geocaching Toolkit iGCT is praised for its ease of use, rich field-calculation tools, and value, helping puzzle solving and multi caches while saving time in the field. Users rely on its projection, bearings, and distance features, and many appreciate offline capability and portability. Common concerns center on limited unit/precision options, missing core features like cache lookups or standalone waypoint tools, occasional accuracy and input metric limitations, and minor stability glitches.

### Pros

- Very easy to use with a clean, intuitive interface.
- Offers a broad set of geocaching tools—bearings, distances, projections, and waypoint calculations—great for puzzles and multicaches.
- Time-saving and handy in the field; helps avoid extra trips home.
- Useful for puzzle-solving and converting coordinates; works offline (e.g., on iPod Touch without wireless).
- Excellent value; many users feel it’s free or worth paying.

### Cons

- Limited unit and precision options: decimal degrees, miles/feet, nautical miles requested.
- Missing core features like cache lookup and standalone comprehensive waypoint functions.
- Some inputs have limited metrics and inconsistent accuracy.
- Occasional stability glitches (e.g., app not resuming cleanly after switching apps; coordinate input glitches).
