geoEarl published

posted 28 Dec 2013, 04:53 by Andreas Greifeneder   [ updated 27 Jan 2014, 12:10 ]

The first version of geoEarl can now be downloaded from the Windows Phone Store. It doesn't offer all the features, that the Pocket PC Geocaching Tools had, especially the GSAK-database support is not available. I see it as an addition to the official Groundspeak app to solve multi caches.

It offers the following features:

En- and Decryption
        • ROT13 etc.
      • Vigenère
      • One Time Pad

Transformation of texts and numbers
  • A=1
  • Roman numbers
  • Phone keypad
  • and some more

Solver with 26 variables

Google dropping support for Exchange ActiveSync (Google Sync)

posted 22 Dec 2012, 03:37 by Andreas Greifeneder

Google announced some days ago, that they will drop the support for their free customers of Gmail and Google Apps by 30th of January 2013. In particular Windows Phone users are affected by this decision. It is to mention, that existing devices, that are already connected via Google Sync, will keep on working. Only new devices will not be able to setup sync connections via Google Sync. More information about this can be found on the help pages of Google.

What are your options now?

  1. For Android users nothing will change. Just setup your Google account and everything will work as usually.
  2. New iOS-users will have to use IMAP, CardDav and CalDav to keep their stuff in sync. CardDav support requires iOS 5+.
  3. Users with new Windows Phones will have the following options:
    • Move your stuff to outlook,com (formerly known as Windows Live Hotmail). Microsoft is still offering Exchange ActiveSync and it's still for free.
    • Pay Google ~ 40 EUR a year and upgrade your account to "Google Apps for business". AFAIK this will only work for accounts with own domains (i.e. instead of
    • Pay Microsoft ~ 45 EUR a year and switch to their Office365-platform (Exchange Online plan).
    • Wait, until Microsoft will offer CardDav and CalDav support. Only time will show, if this ever will happen.
As all my devices are currently connected via Google Sync, I can postpone the decision. I still don't know, what I will do, when I'll get a new device, i.e. one of those new Windows 8 tablets. :-)

Windows Phone App in development: geoEarl

posted 19 Sep 2012, 13:16 by Andreas Greifeneder   [ updated 19 Sep 2012, 13:28 ]

Well, there is not too much to show at the moment, but still I want to annouce, that I have another Windows Phone app in development. The logo on the left looks similar to you? OK, then you might already have guessed, what it is: Yes, those are "Pocket PC Geocaching Tools" for Windows Phone. Well, as the old name doesn't make too much sense anymore, I decided to rename the software to "geoEarl". Or maybe I'll call it PPC-GCT-FWP ;-)  

The picture you can see on the left is just the splash screen of the app. Some modules are already finished, but the main part is still to come: Open GSAK databases. The main problem here is: How to transfer a database with hundred(s) of megabyte to the phone in a fast and convenient way? Not to talk about hundreds of grabbed images and spoilers. Maybe Windows Phone 8 has some new options to achieve this. 

The software is still in early development, so don't expect anything in the near future. Maybe I'll publish the app without the GSAK part at the beginning. 

Let's see.....

New Windows Phone App

posted 19 Sep 2012, 12:48 by Andreas Greifeneder   [ updated 19 Sep 2012, 13:29 ]

Some days ago I published a small app called DaysTo Christmas

It will show you how many days are left until the next Christmas. You can choose if the app should count until the 24th or the 25th of December. 

The app is not free, but will cost 0,99 EUR/USD or that amount in your local currency. 

It's available in all markets, that are supported by the Windows Phone Store. The language of the app is English.

Get it now on the Windows Phone Store!

smsEarl Version 1.2 veröffentlicht

posted 19 Sep 2012, 12:27 by Andreas Greifeneder   [ updated 19 Sep 2012, 13:31 ]

Die SMS-App für ist jetzt gratis in der Version 1.2 im Windows Phone Store verfügbar.

Neben dem neuen Namen gibt es folgende Verbesserungen gegenüber der Version 1.0:

  • Der aktuelle Kontostand wird nun angezeigt.
  • Fehlerbehebung beim Senden von SMS mit Umlauten.
  • Eine Liste der gesendeten SMS kann nun abgerufen werden. Der Posteingang kann leider über die nicht abgerufen werden und steht daher auch in der App nicht zur Verfügung.

Developing on an Android device for Android devices

posted 25 Apr 2012, 12:13 by Andreas Greifeneder

If you want to develop apps for Android (phones or tablets) you have to download the Android SDK to your PC (Windows, Linux or Mac OS X) and some kind of IDE. Most will use Eclipse. Right?

Not anymore. Recently I found a quite interesting piece of software: It's called AIDE (Android Java IDE). With this app you can develop Android apps directly on your Android device.

You can edit the Java code, build the apk and it also offers Git integration.

Now all I need is an app idea and some more Java knowledge.....

Android tablet Acer Iconia Tab A200

posted 21 Apr 2012, 04:06 by Andreas Greifeneder

I own an Acer Iconia Tab A200 (click here for technical specifications on amazon) for a few weeks now. Compared to the iPad 1, that I had before, I see the following advantages/disadvantages: 
  • The A200 has a higher display resolution and it's therefore a bit sharper (the new iPad 3 should be even better), which makes it more comfortable to read eBooks.
  • There is an USB-port on the A200, so you can attach an USB-drive or a mouse or keyboard. Furthermore you can insert a Micro SD Card directly.
  • At the moment there are more optimized (and useful) apps for the iPad compared to Android tablets. Especially when it comes to eMagazines.
  • The support for google services on Android devices is generally a bit better compared to iOS. That's only an advantage, if you, like me, use them a lot.
  • Official support for Apple services on Android devices doesn't exist.
  • The iPad (even it was the first generation) was a bit more stable and smoother.
  • The battery life of the iPad was better also.
  • Adobe Flash is supported on the A200, while not on the iPad. But Adobe announced, that Android 4.0 will be the last version, that will be supported.
These are just my personal impressions. Others might not agree :-)

Pocket PC Geocaching Tools for Android

posted 9 Apr 2012, 11:50 by Andreas Greifeneder

No, I haven't ported my tools over to Android. But I had a look at Android software, that can replace my software. I haven't found an all-in-one-solution, but found two different apps, that do the job:

GDAK - Geocaching Droid Army Knife
This very nice piece of software does the database part of the PPC-GC-Tools: You can open GSAK-databases and have pictures and spoilers offline. Furthermore it's even possible to navigate to a cache using the built-in GPS of your Android device.

You can find GDAK on the Google Play Store here:

GCC - GeoCache Calculator
This is a collection of many useful tools for geocachers. There are many tranformations and decryptions available. But you can calculate formulas of multi caches also.

You can find GCC on the Google play store here:

Compared to the PPC-GC-Tools these two apps are much more powerful. Check them out, if you have an Android device.

sloono SMS v1.0 veröffentlicht

posted 7 Nov 2011, 02:23 by Andreas Greifeneder   [ updated 7 Nov 2011, 02:27 ]

As this is just interessting for german speakers, the following text is in german only.

Soeben wurde meine erste Windows Phone 7-App veröffentlicht. Sie wird wahrscheinlich nur für wenige Leute von Nutzen sein. Hauptsächlich habe ich sie aus Eigeninteresse programmiert, da ich kein SMS-Paket bei meinem Handyvertrag habe, jedoch ein Datenpaket. Daher nutze ich bereits seit längerem, um meine SMS zu verschicken. Es gibt dort zwar auch eine Mobilseite, jedoch muss man dann immer die Kontakte hochladen, damit man sie auswählen kann. Mit meiner App "sloono SMS" kann ich jetzt aber direkt auf die Kontakte auf dem Handy zugreifen.

Vielleicht kann das ja noch jemand brauchen...

Den Download gibt es auf dem Windows Phone Marketplace:
