Four bars. Full signal.
Everything just works.

Gridless is an offline AI survival companion for iPhone and Android. Answers, identification, maps and a whole library run on the phone itself.

02The assistant

Ask out loud.
Tick it off.

A small language model, such as Gemma, runs on the phone and answers from your downloaded survival guides, books and your own PDFs. Step-by-step answers come back as a checklist you can work through with cold fingers.

How do I build a fire?

Illustrative demo. In the app, answers come from your own downloaded library.

03Photo identification

Honest words.
Never a percentage.

Point the camera at a plant, fungus, bird or animal, offline. Gridless shows the likely names with lookalikes alongside, and says how strong each match is in plain words. Saved finds go into your Field Journal.

  4. Wood HedgehogHydnum repandumLong shot

Several orange woodland mushrooms look alike, including poisonous ones.

A match is a name, not permission. Gridless never tells you something is safe to eat or touch.

Illustrative example. Real results depend on your photo.

04Offline maps + GPS

Save the hill
before you climb it.

Pick an area while you still have signal and Gridless saves the OpenStreetMap street and trail map onto your phone. Out there, it loads with zero bars and GPS keeps your dot on the path.

The strobe here is a demo. The app's torch and SOS screen use your phone's real light and dialler.

06The bookshelf

A library in a pocket
that weighs nothing.

Survival guides, field manuals, public-domain survival books and offline reference packs, up to all of Wikipedia. The assistant reads from them so you don't have to.
