Building for the Phone You Already Carry

The homepage used to show a dead iPhone, then ask you to install a laptop app.

That was honest about the problem and dishonest about the product. When the network is gone, you are holding a phone. First responders and hikers do not pack a 15 GB desktop install for a day hike. We are changing the lead platform.

What stays true

The app still does not need a network after you have downloaded it. Answers still have to come from the library on the device, with a citation you can open. Medical topics still carry their sources. We still will not sell fear, and we still will not pretend a model “just knows” anything the library does not.

What changes

iPhone becomes the product. Three nouns, in order: Library, Field, Ask. A library of 101 sourced guides that works with no model installed. Field tools: leave a card, routes saved as text, last known, compass, light and signal, the lost sequence. Ask is optional, runs on the device, and cites the guide it used. Supplies stay, under Settings, for the day you have a shelf.

What we are not putting on the phone: live maps, live navigation, mesh. Routes are directions you saved while you had signal, kept as text. Last known is a position you mark, not a tile you download.

We are not squeezing the 15 GB laptop stack into the App Store. That would be a lie about both battery and size limits. The phone gets a compact model, installed in one tap over Wi-Fi, in a Compact or Recommended pack. Same brand, same citation rule, different binary.

Price

The app will be free. Library, Field, and Supplies work without paying. Ask, with the on-device model, is planned as a one-time unlock at $19.99. Not a subscription. It is not on sale yet.
