Two million users!

If you can believe the numbers provided by the Android market, RealCalc has now reached over two million active downloads. To celebrate, I shall be buying myself a pint (that's a UK pint, 1.2 of your US pints or 568ml).

Thanks to everyone for your support.

RealCalc v1.4.5 released

What's new:

  • Reverted to old package name to fix upgrade issues.

It seems that the custom home screens provided by HTC, Samsung etc don't like it when you change the name of the app's main activity, and leave a broken shortcut on the home screen and possibly in the app menu as well. Unfortunately this means I've had to revert the name and release again.

If you get an error such as "the linked application is no longer installed on your phone", then please uninstall RealCalc via the Market app and then download it again. If this does not fix it, please try rebooting your phone after uninstalling, then reinstall.

Apologies to those who installed v1.4.4 and have already hit this problem, as you'll need to uninstall a second time to get v1.4.5. Anyone upgrading straight from v1.4.3 to v1.4.5 should be ok.
