If the lights went out tonight

Your emergency kit, scored — and never expired again.

Lantern gives your home a Ready Score, tracks every expiry date and gear check, and keeps your family plan — 100% on your phone. No account, no cloud, no bars needed. Because an app that needs a login fails exactly when the towers do.

🔒 Zero personal data. “Water × 12 gallons” identifies no one — and it never leaves your device.

How it works

Check things off. Watch your score climb. Sleep better.

Start from the built-in 72-hour essentials checklist (FEMA-style) — your kit is born as an honest to-get list, and every ✓ moves the score. Then Lantern quietly keeps it alive.

🏮

The Ready Score

One number for “would tonight be okay?” — weighted across stocked, expiring, untested and missing. 80% feels very different from 45%, and both are fixable.

Nothing expires on you

Water, cans, meds, batteries — Lantern reminds you two weeks out, and one tap logs the rotation with a fresh shelf life. Rotate it into the pantry; waste nothing.

🔦

Gear checks

A flashlight you never test is darkness in a drawer. Flashlights, radios and power banks get a test cadence — “Tested today ✓” takes one tap.

💧

Water math, done

Tell it your household — adults, kids, pets, 3 days or 2 weeks — and Lantern computes the gallons you actually need vs what's on the shelf.

🎒

Every kit, one app

Home kit, go-bag, car, work. Each scored on its own, each with its own checklist — because the emergency doesn't ask where you are.

🗺️

The family plan

Meeting spots, the out-of-area contact, shutoffs, the school's plan — the ten non-gear steps that matter most, as a simple checklist.

Why local-first isn't a feature — it's the point

Preparedness apps that need a login
fail when you need them.

Cell towers go down. Logins time out. Clouds are unreachable in a blackout. Lantern keeps everything on your device, works with zero signal, and can print your whole plan to paper — the only backup that needs no battery at all. And because there's no account and no upload, there's nothing to leak, sell, or subpoena. Your readiness is nobody's business.

Pricing

Your safety net shouldn't charge rent.

Free covers a home kit and a go-bag, forever. Pro is a one-time purchase — no subscription, because a $5/month kit list is exactly the kind of thing 2027 doesn't need.

FAQ

Fair questions.

Does Lantern send emergency alerts?

No — on purpose. Alert apps need servers, accounts and signal, and there are good free official ones (FEMA, NWS). Lantern does the other half nobody does well: making sure that when the alert comes, your kit actually works. In an emergency, call 911 and follow official guidance.

Where is my data stored?

Only in your phone's local storage. There is no account, no server, no analytics on your supplies. Delete the app and the data is gone — that's how little we hold.

What happens when I switch phones?

Export your household plan as a PDF (Pro) — it's your paper backup and your re-entry checklist. A local file export is on the roadmap.

Is the checklist trustworthy?

The starter lists follow common FEMA/Red Cross-style guidance (water: 1 gallon per person per day, 72 hours minimum). They're suggestions to adapt, not professional advice — ready.gov is the authority.

Why one-time instead of subscription?

Because readiness is infrastructure, not content. You buy a fire extinguisher once. Pro is $8.99 once, and it keeps working — online or not — for as long as your phone does.
