iGeoCacher User Guide/Videos

Version 2.6 is current in the App Store. (I know, next up I need to update all of the following docs. I'm working on it!)

You can now load unzipped geocache data files (.GPX, .LOC) by directly dragging and dropping them in the iTunes File Sharing area for iGeoCacher!

Watch a movie showing how to load from iTunes Drag and Drop.

Important note: GPX files can be large and the email client in the iPhone will not typically download them from your mail server until asked by your touching the attachment first. You can tell if the attachment looks like this:


When it is fully downloaded it will look like this:


Make sure that you have fully downloaded it into your email client on the iPhone BEFORE you try to load it into iGeoCacher.



I've started a new videos page and I'm moving the existing videos over there. I'll be replacing them with new content shortly.

So, new users, please take the following with a grain of salt. The info is still useful but it is now getting dated. I hope to have new videos up this week. Stay tuned. By all means drop me a line if you are confused by anything. The Yahoog group is great for support as well.

Firewalls and Other Security Software

Be aware that firewalls and other security software you might be running on your target PC may prevent your iPhone/iPod touch from successfully reading the GPX/LOC file with the inbound port 80 request. If you are having connectivity issues you may want to temporarily disable this software just to see if it is the culprit blocking you. Most such software has the ability to tailor access by authorized outsiders and you may have to so designate your iPhone if you find that it is being blocked.

Using your me.com account

This from one user that uses his me.com account:

"Good news! I've successfully managed to load GPX files from my public iDisk. It took a little experimentation. URL of the form


don't work but I suspect this is due to a redirect not being handled by the mechanism used by iGeocacher.

However, if you use the following format


it works."

Known Issues November 26, 2011

You may get a "null" file message when loading from the file menu. I've fixed this one in the 2.7 version just submitted to Apple for review.

Also, I've removed the button for Ayefon server download as this will no longer work since GoDaddy dropped support for Cold Fusion on their servers. That was really a legacy method dating back to the original iGeoCacher web app anyway. Since iOS 4.x, using email attachments or iTunes file sharing is far superior.




Tip to check connectivity:

To check your download URL for connectivity and service apart from the iPhone/iPod touch, just put the URL in your browser. This is the same URL that shows up in the download acknowledgement alert (if you have alerts turned on in settings.) Your browser should display the XML data from the cache file. If that works you know you got the connectivity and URL right.

Use screen shots for offline map access

For maps when you know you will likely be "off line" without the connectivity that the Google Map app requires, use the built in "screen shot" capability to just store the maps you think you'll need in your iPhone/iPod Touch photo album before you go. Then you can easily refer to them when you are out in the field. How do you take a screen shot? It's easy. Just bring up the screen you want, then hold the top button (the on/off button) and while holding it momentarily press the home button. The screen will flash and its image will be saved in your photo album.

Take advantage of the "Mark" button on the GPS display

When you need to enter ad hoc coordinates in the WPT display, chances are they aren't too far from where you are at the moment. Just hit the "Mark" button on the GPS display and your current location will populate the WPT fields. Then just tap the fields and back out the last few digits in the lat and lon as needed and change them to your target. Change the title also if you wish. That minimizes keystrokes and entry errors for the second and third stage coordinates.
