This is the Pro version of Time Recording - without advertisement and with Calendar Sync unlocked. Use Time Recording Free first if you are new to this app.

What's the difference between Free and Pro:
• Free version shows advertisement and has Calendar Sync locked initially. Other than that the apps are identical.
• Starting with version 6.01 Free version offers in-app purchases to hide ads for 12 months and to unlock Calendar Sync permanently.

Migration to Pro:
• Migration from Free to Pro is very easy: install and open Pro - the app will prompt for import of data and settings from the Free version.
• Usage of Free and Pro version in parallel is supported but may lead to confusion. Consider uninstalling Free a few days after going Pro.
