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. Wear OS support, added with Version 7.60: • Use the Wear OS companion app to perform basic tasks (punch, check status) on your Wear OS watch.
