This requires a separate purchase of iRT Calendar.
 

3. iRT Calendar for Android 1.5

Supports most of the power features and elegant design of iRT Calendar. Phones with Android 1.5 however have limitations in terms of hardware capability and modern Android features thus making it not upgradable with the Pro Key for professional version features.
 
4. iRT Calendar Pro Trial
The trial version of iRT Calendar Pro Key and iRT Calendar. iRT Calendar Pro Trial can be installed side by side with iRT Calendar if the user wants to try iRT Calendar Pro Trial before buying the iRT Calendar Pro Key. Data backups from iRT Calendar Pro Trial can be used to restore data on iRT Calendar but if some Pro features have been saved on the Pro Trial it would appear on iRT Calendar but won't be modifiable, decorators like font color, done indicator, highlight or float. Note: iRT Calendar Pro Key does not unlock this trial version, you need to buy iRT Calendar and iRT Calendar Pro Key to get the full version, see items #1 and #2 above and uninstall this trial version.
