iPhone · Local only
On a trail or at home: answers, supplies, and a plan on the phone you already carry. Ask is optional.
Free when it ships · Ask unlocks once · No subscription
Home
Home opens on four doors. Short physical steps first, then the full guide. Quiet facts only when they exist: days of water after you add water, last known after you mark one, your plan after you save one. No dashboard of missing things.
Trail
Stop. Do not start a new walk.
Then the lost sequence in Field. Stop. Mark. Stay. Signal. Each step keeps the time you marked it.
Home
Light, food, and do not heat with the oven.
Then the At home shelf: the first hour, the first night, the first week. Generator and carbon monoxide. Food when the fridge is off.
Trail or home
You first. Then bleeding. Then the guide.
Then the first-aid shelf: injury, bleeding, and wilderness medicine. Thirteen guides.
Trail or home
Boil if you can. Clear is not clean.
Then Water: find, filter, and make it safe. At home, water when the tap fails.
01 · Library
This is what you have the day you install. Every guide carries a Sources line: CDC, FEMA, Red Cross, WHO, USDA, NFPA, USGS, NWS, land agencies. Open a chapter, or search. Results open at the matching section, and the reader resumes where you stopped.
Start here Power Outage at Home · Wilderness First Aid Basics · Water Purification Methods
Eleven topics
First aid, Water, Fire, Shelter, and At home are pinned first. Trail hazards in this pack include wildfire on the trail and flash floods in canyons and washes.
The reader
Text size stepper. Outline. Jump to quick reference. Continue where you left off, by section, not by guide.
At home · twelve guides
02 · Field
Leave a card: where you are going, when to worry, and a Text button that prefills Messages. Mark last known. Compass, light and signal, radio reference. If you are lost, the sequence is on the screen. Stop. Mark. Stay. Signal. Call, only if a number still works.
02 · Field · Routes
With signal, once, the app fetches directions from Apple Maps and saves them as a text card: steps, distances, coordinates, time, an optional Plan B. With no signal the card still reads, and from a marked last known it shows the bearing and distance to the next step. No map is drawn.
Roads can change. This is a plan, not live directions.
03 · Ask · Optional
Ask runs a model on the phone and writes only from the library. One plain lead sentence, then What to do, numbered, with the source marked on every step. Open the guide lands on the cited section. Plan this situation writes first minutes, first hour, first day for your house and keeps it on Home as Your plan. With no model installed, Ask says so and the library still answers.
One-time unlock, planned at $19.99. Not a subscription. Not on sale yet.
03 · Ask · How it works
Ask is a model that runs on the phone. It does not answer from memory. It reads the library you already have, writes from what it finds, and marks the source on every step. If the guides do not cover it, it says so instead of guessing. Questions to Ask never leave this device.
01
Type it, or tap a door. Nothing is sent. There is no account to sign in to and no server to reach. The model is a file on the phone.
02
Retrieval pulls the passages that match from the 101 guides. Instructions, not caveats. The same guides you can open and read yourself.
03
One plain lead sentence, then What to do, numbered. The [S2] on a step opens that guide at that section. No match in the library, no answer.
A fair test
Switch on Airplane Mode. Ask again. Same answer, same sources. Nothing about Ask needs signal once the model is on the phone.
Turning it on
One tap over Wi-Fi. Compact or Recommended pack. One-time unlock, planned at $19.99. Not a subscription. Not on sale yet. Without a model, Ask says so and the library still answers.
Also on this phone
Days of water, food, and meds for your household, and which runs out first. Under Settings until you have a shelf. Empty is an invitation, not a count of zero.
Pick the event, the people, the place, the risks. Ask writes first minutes, first hour, first day. Save it, and Home shows it as Your plan.
Return-time chips. Share. Text a contact with Messages prefilled. If you are late, Home says Card overdue, with I'm back.
Flashlight. Three flashes or SOS in Morse. A phone without a torch flashes the whole screen white, with a Stop button.
Channels for North America, Europe / UK, Australia / NZ. Marine 16 and aviation 121.5 everywhere. A MAYDAY script that fills in your position. The phone is not a transmitter.
Paste a coordinate pair and it splits. Fixes older than six hours say how old they are. One GPS fix when you ask for it. Never tracking.
Home says whether the phone has a network path right now. Two jobs need signal once: install the model, save a route. Nothing else does.
Backup export. Delete everything on this device, in Settings. The built-in library stays. Sunlight and field palettes for the screen you are holding.
Two things it is. Two it is not.
What ships
Library, Field, and Supplies work the day you install. Ask works once a model is on the phone.
Local only
No account. No analytics. No cloud answers. Questions, supplies, contacts, and routes stay on this phone.
Reference, not care
Guides and answers are sourced reference for people without help on the way. They are not a clinician, and they do not replace one when you can reach one.
Not a map
No tiles. No live navigation. Routes are directions you saved while you had signal, kept as text. Roads can change. This is a plan, not live directions.
Get NoSignal
Library, Field, and Supplies work the day you install. Ask is a one-time unlock, planned at $19.99. Not a subscription. It is not on sale yet, so there is no buy button here.
Model install, when you want Ask: one tap over Wi-Fi. Compact or Recommended pack.
Questions
No. Once the app and the optional model are on the phone, everything runs on the device. Airplane mode is a fair test.
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.
Ask is disabled and says so. Library, Field, and Supplies work anyway. There is no cloud fallback, so nothing is presented as offline that is not.
No. Routes are directions you saved while you had signal, kept as text. Roads can change. This is a plan, not live directions.
No. Guides and answers are sourced reference for people without help on the way. They are not a clinician, and they do not replace one when you can reach one.
Three things you start: downloading a model, planning a route with Apple Maps, and sharing a card or plan to another app. No analytics, no crash reporting, no account. This website uses analytics. Privacy.
