Black Friday and price change

Not so often in the history of iCaching I have done promotions. Actually only once on the 10th anniversary. But this time I make an exception; with all the higher cost for living and energy, I give a 35% discount on iCaching for a week, starting now!

And even bigger news: I also never changed the price tier of iCaching. The only price fluctuations throughout the years have come from Apple changing the prices because of exchange rates. However with the current expensive dollar (for us Europeans), I think it is time to choose a lower price tier. So after the Black Friday promotion I will also lower the normal price around 20%.

Note: the price of iCaching is a perpetual license, not a subscription. So pay once, enjoy forever.

Tell your friends, enjoy iCaching!

New: Czech localisation

The biggest new thing in the latest iCaching version is the addition of Czech localisation. Geocaching is pretty big in the Czech Republic and I got several request for this locale. So now finally its there 😉

iCaching now supports 5 languages: English, Dutch, French, German and Czech.

Hereby a big thank you for my translators; Richard, Ange and Joerg!

Raising minimum macOS version

It’s never nice to abandon an old macOS version. But from time to time, I have to do that. This is the only way to be able to use Apples latest APIs and techniques.

The version that I will drop from iCaching 10.4 is macOS 10.12 (Sierra). The good news is that all Macs that can run macOS 10.12 can also run macOS 10.13 (High Sierra). So if you want to have the latest iCaching, you can update your OS and you’re good. Moreover: everyone should always try to keep up with the latest possible macOS update for their machine to get the latest features, fixes and more importantly: the latest security updates.

So this time it should not hurt anyone 😉

Export to GGZ and macOS Monterey 12.3

Recently Apple released the latest update of macOS Monterey version 12.3. Since that version Apple removed the build in Python support. Unfortunately exporting geocaches to GGZ relies on a Python script that converts the GPX files to a GGZ file. This means that export to GGZ is not working anymore from this macOS update.

I looked for a short time solution (manually installing Python), but that did not work out. So I am now rewriting the export and replicate the steps that happened within the Python script in native (Swift) application code.

As you can imagine, that is not a few hours task, but quite big. So while I work on that, please don’t update to this latest macOS version if you rely on GGZ files in your workflow. I will update this article when the fixed update of iCaching goes out.

Sorry for the inconvenience.

Update: The version (10.2.1) with a fixed GGZ implementation is live

Bookmark sync feature

Hello iCachers,

It’s been a long time since the last post here. This summer I quietly released iCaching 10.0 with a very great new feature: automatic sync of bookmark folders.

When you have bookmark lists on the website, they will now automatically appear in the left pane of iCaching. Changes you make to the list in iCaching will sync back to and vice versa. These Bookmark folders work like the normal Folders in iCaching, so you can drag and drop caches in them, remove caches from them etc. But then it syncs.

This makes iCaching the perfect companion for the mobile geocaching apps; first you start exploring a nice collection of geocaches on your big Mac screen, and put them in a Bookmark folder.

Then you go out in the field with the mobile app and search geocaches from the synced Bookmark folder in the app. For the geocaches you find, you create a quick ‘draft’ log in the app.

And once your back home, enjoying a nice coffee or beer, you go to the Log window in iCaching and you get the draft logs from and you make nice complete logs from them, describing your adventures finding those caches.

I really hope you enjoy this feature, and please let me know what you think of it.

Happy (i)Caching!

Happy birthday; iCaching 10 years!

Unbelievable, but it is already 10 years ago that iCaching was released in the (then brand new) Mac App Store.

As geocacher and Mac user I was at that time searching for a tool to help me prepare geocache trips. But there were only a few very limited tools available. When I prepared a trip with a friend I was a bit jealous on his Windows tool called GSAK. In the same period I was trying to figure out developing software for the Mac as a hobby, while I created some small tools on Windows before I switched to Mac. So that became the start of iCaching.

Few months after I had the first very limited version of iCaching, Apple introduced the Mac App Store. Then it became my goal to make my little tool available for other Mac geocachers. Around three months after the inception of the App Store, I had a version that was good enough to release to the public.
For reference, the most actual macOS version at that time was 10.6 Snow Leopard.

iCaching 1.0

In all those years, many many hours of development went into the app, which is now a really mature versatile geocaching tool. My goal is still what it was back then: make a tool that is easy to use in a way that Mac users expect. So respect the user interface guidelines and sometimes don’t add features if it will make the user interface cluttered and unclear.

I wish everybody a lot of fun with iCaching in a lot more years to come.

Ps. If you want to recommend iCaching to a geocaching mate, then now is the time to do so. For this special occasion I do a one time promotion with 30% off the usual price from March 15 to April 14 2021.

Personal note and coordinate sync

Hi dear iCaching people,

Last week a new version of iCaching rolled out. The tentpole feature of this version is the new sync for personal notes and corrected coordinates.
This was a much requested feature.

At first I was hesitant to build it, because of the fact that it will overwrite the values that you might have entered on Therefore, when you change a personal note (the yellow area on the Info tab) or you change a corrected coordinate, iCaching will ask you if you want to send it to
You can check the ‘never ask again’ button to remember your choice depending on your preferred workflow. You can always change this choice in the Preference window.

When syncing personal notes, iCaching needs to do a separate network call to the Geocaching API for every single note. And this is only allowed once every two seconds. So when editing several notes simultaneously , this could have resulted in a very slow operation. This meant that I had to remove the ability to edit the personal note for several selected geocaches in one go.

If your workflow depends on downloading GPX files from Geocaching (instead of calling the API functions to download geocaches), then be careful; if you send the corrected coordinates to, they will replace the coordinate in GPX files with the corrected one without any indication that this is a corrected coordinate. So when you import those into iCaching, the original coordinate will become the same as your corrected one, which might be very confusing. In the API responses there are luckily separate fields for original and corrected coordinates. So no problem there.

Groundspeak only allows this feature for premium users.

I really hope you enjoy this new version!

Happy (i)Caching in 2021

Happy new year folks. Wish you a good and healthy year with a lot of finds!

Version 9.0.1 out, problem solved :-)

Last week I proudly released version 9.0 of iCaching with a whole new look, fitting in macOS Big Sur and native support for the new M1 Apple silicon Macs.

Unfortunately, the new search item on the toolbar appeared to crash on machines that are not upgraded to macOS Big Sur yet, even though Apple promised that this search item is backwards compatible.

So I stopped the roll-out of version 9.0 (only 10% of you received that update yet) and submitted version 9.0.1 in which I reverted to the old search item.

Version 9.0.1 is now available with a fix for this problem. Sorry for the inconvenience

It is coming….

Today is a very special day, Apple will tonight announce the first Macs with their own processor replacing Intel processors. I also expect them to announce macOS 11 Big Sur availability somewhere this week.

The good news for iCaching: I am almost ready with a new look fitting in the new Big Sur design language. And also native support for Apple silicon!

Here as a sneak peak, I reveal the new app icon. It fits in the now all rounded-rectangular icons for Big Sur. The color is closer to the Geocaching green and the GPS looks a bit more modern. Watch out for version 9.0, soon in the Mac App Store… Keep you posted

Happy (i)Caching
