Mostly Harmless Development
Your state's law, in your pocket — fast, searchable references to state law on phones, tablets, and the web.
Law Library Plus is the platform behind our family of state-law reference apps, including TCA Plus (Tennessee) and Iowa Code Plus (Iowa). Each app carries its state's full code, court rules, fine schedules, and field resources, with fast full-text search, live citation links, and offline access. Built for the people who use the law every day: police officers, attorneys, and paralegals.
One Law Library Plus account — created with an email address or by signing in with Google or Apple — works across all of our apps and the web, and keeps your bookmarks, reading history, and subscription in sync on every device. Free to start; one low annual subscription per app unlocks everything.

How we build
Every app carries the complete, current text from official state sources, with fast full-text search, live citation links, offline access to what you've saved, and sync across your devices. Content updates land server-side — no app update required when the law changes.
No ads, no tracking SDKs, no data sales. The statutes belong to the public; our work is making them fast to use.
