What is the difference between the 'Pro' (paid) and the 'non-Pro' (free) versions?

Both versions are the same app and have the same features.
The ‘Pro’ version is a paid app in the App Store.
The ‘non-Pro’ version is the free version of the app. The free version limits the amount of tasks that can be entered through the app. Purchasing the app removes this limitation.
The free version gives an opportunity to test-drive the app before you buy it.
