Use it offline

When disaster hits, the internet is often the first thing to go. Tap Save for offline and every guide and checklist on Prep Index is stored on this phone or computer. With no signal, open prepindex.ai as normal and it still loads. Only the live map needs a connection.

On a phone, also tap Share, then Add to Home Screen, so it opens like an app. Tap the button again now and then to pick up new entries.
