Pros: Easy to use once learned. Great resolution compatibility. Solid performance. Lots of tweaks that can be done.

Cons: Limited fractal options. Some saving issues. Slightly unfriendly interface. Can't save settings.

Pros: Great looking traditional and modern interfaces. 150 levels. Addictive.

Cons: Some of the puzzles are boring. Access to some puzzles is limited to full version.

Pros: Results are in a text report. Alerts you to potentially dangerous app issues. Also lists invisible items. Results are in full sentences rather than data blocks.

Cons: Full version project has been abandoned. Manual/tutorial is very small. Non-developers will struggle to use this app. Requires backward compatibility to OS X 10.11 (El Capitan).
