### 5/5 — Amazing. Hands-down.

*2026-07-12*

This app is genuinely  a godsend. Has a DB of every character + every story, has a headhunt tag filter system, story tidbits from every IS, and a lot of other miscellaneous tools I'm sure many doctors out there would benefit from. I wish that the CN units had their kits translated, but that's a minor nitpick, and the app is still VERY useful even w/o it.
