Cache

An offline preparedness app you fill with what matters to you. Everything runs on your phone, so it keeps working with no signal.

What it does

Ask

A private AI assistant that runs on the phone. It answers from your own references, maps and live data, and shows its sources.

Library

Wikipedia, WikiMed, survival manuals and more from the Kiwix catalogue, searchable offline.

Maps

Offline maps with road routing and turn-by-turn directions. Download a region, from part of a state to a whole country.

Weather

Forecasts, alerts and wildfires for your places, updated in the background, with pop-ups for new warnings near you.

Sharing and sync

Keep your devices in step, directly on the same network or over the internet.

Yours to fill

Cache ships with no data and no model. You choose a model from Hugging Face and the sources you want.
