## What is Geocaching Toolkit iGCT Pro?

The iGCT PRO app is a toolkit that focuses on typical tasks performed during geocaching. Tasks like making a projection from a waypoint, determining a new waypoint using two other waypoints, determining the distance to these waypoints, calculating the value of a Roman numeral, and averaging waypoints are examples of what the toolkit can accomplish.

Imagine it’s lovely weather and you are walking in a beautiful surrounding. Walking with an intention, because you are geocaching and searching for caches.

Picture you are at waypoint 3 of a multi cache and you’re asked to go to waypoint 4, which is 300 meter from this waypoint and 700 meter from the previous waypoint. Now what? Go home? Imagine you have a skilful toolkit with you to find your way. Imagine you have iGCT PRO, because you want to be ready for all these kind of challenges.

Buy it now for a fixed low price (no in-app purchase necessary), since you never know if you have internet access the moment you need it most!
The choice is yours.

Complete feature list:

List of waypoints
=================
- Averaging a number of GPS readings for accurate coordinates
- Manage a list of named waypoints
- Search/filter list of waypoints
- Show overview map with all (filtered) waypoints
- Manually add a new waypoint
- Edit latitude, longitude in WGS84, degrees, DMS, UTM, Dutch/Swiss XY

### 4/5 — Wäre perfekt, wenn eine Kleinigkeit nicht fehlen würde.

*2023-06-28*

Ich würde die App als Schweizer Taschenmesser es Geocaching beschreiben.
Was ich vermisse, auch in der pro Version, sind das aufzeigen von Buchstabenwerten aus ganzen Wörtern oder Sätzen. Also nicht die Summe, sondern Buchstabe für Buchstabe als einzeln angezeigt der Buchstaben wert.
Z.B. Der -> 4 5 18
Das würde manchen Multi und deren Aufgabe sicherlich erleichtern.

### 5/5 — A wonderful “Swiss army knife” of Geocaching tools

*2022-02-02*

I love this app! This app is very useful in the field for solving cache puzzles and calculating projections and making conversions.  But I found it the perfect set of tools for creating caches.  The waypoint averaging tool for creating accurate Ground Zero coords is alone worth the price of admission.  Whether for a single cache location or creating  series of locations in a multi-cache, the ability to quickly obtain coords and average and save is a huge time saver.  The ability to see the various readings with a nice graphic view really helps to see outliers in the data and edit.  

I also use the projection tool for creating bearing and distance information in designing caches.  I just accurately (averaging) locate the various Stage Locations and then use the app tools to figure out the correct bearing and distance information that connects the waypoints.  

The ability to obtain, average and save the coords to a waypoint list is ideal for establishing general hiking trails that are not geo-cache related is a bonus.

The app also has very good context related help information in addition to being able to obtain and print a full manual.  

The app tools us a well though out menu system.  I also liked the ability to copy/save/paste information between app tools.  It would seem that this tool is made by a geocacher who understands what geocachers really need to enhance this pastime.

### 1/5 — Can’t change the directions

*2020-11-01*

This geocaching application for geocachers in the Northern hemisphere is absolutely useless because you can’t change the directions inside the application.  I can’t change the E direction to a W direction to get a North/West coordinates for marking waypoints.

**Developer response:** Just click on the green E, it will flip to W. And vice versa!

### 5/5 — Unentbehrlicher Helfer

*2019-08-20*

Auch diese App benutzen wir (neben dem Geocaching Buddy) schon seit vielen Jahren und sind von den Werkzeugen begeistert.

### 5/5 — App stürzt ab

*2019-03-24*

Ich hatte heute einen Fehler in der App bemerkt und den Entwickler angeschrieben. Innerhalb weniger Stunden gab es schon Hilfe. Perfekt!
Die App hilft mir viel beim Cachen und ich nutze sie regelmäßig.

### 5/5 — Geocaching-Multitool

*2017-09-13*

Vielen Dank für das tolle Update - die App wurde dadurch ja noch besser.

### 5/5 — Gute App

*2017-09-05*

Bitte haltet diese App am Leben. Mit dem kommenden Update auf iOS 11 wird diese Version nicht mehr kompatibel sein.
Bitte entwickelt die app weiter.
Ich finde die Funktionen alle sehr hilfreich.

### 1/5 — Reinfall

*2013-02-11*

Außer für selten benötigte Peilungen und Koordinaten Berechnungen ein wahrer Reinfall. Andere Apps kosten weniger und bieten z.B. reichlich Konvertierungen.

### 3/5 — Im Grunde gut

*2013-01-12*

Eure App ist schon toll. Nur schade, dass der Vanity Code fehlt

### 2/5 — Unzufrieden

*2012-11-11*

Also ich bin für den Preis mehr als unzufrieden! Sicher gibt es viel nützliches in dieser App aber für den Preis sollte zb das Peilen etc einfacher gestaltet werden!!
