Game Changer

Impressed with the glossary and exploits widget. Tight UX. Clean implementation, super snappy. Having it on the home screen makes it convenient.

Pretty neat!

Enjoyed all the latest exploit data to search through and enjoyed the memory exam section the most. :)

Surprisingly thoughtful, stuck with me

dowloaded out of curiosity and didn't expect much, but it actually held my attention longer than most apps like this. the interactions and actually tapping the vulnerable lines/code make you pause and think in a different way. some pretty funny easter eggs too. i've found myself coming back to it without really planning to, which says a lot. simple ideas but they work.
