When disaster strikes,
the internet goes down.
Every modern survival resource assumes you have connectivity. In the worst moments — the exact ones where you need help most — that assumption fails completely.

Americans
are underprepared for a 72-hour outage
01
No signal, no Google
Wildfires, earthquakes, solar flares — they all kill the grid before you can search for help.
02
Other apps need accounts
Every survival app asks you to sign up. TLM needs nothing. Download and go.
03
No offline maps exist
Most apps cache text but not maps. We bundle everything you need before disaster strikes.
Why not just Google it?
When the grid goes down, everything you rely on disappears. Here's how the options stack up when it actually matters.

Built for the worst day of your life.
Every design decision was made assuming connectivity is zero, battery is low, and hands are shaking. This is a tool, not a toy.
100% Offline. Always.
Every page, every map tile, every instrument runs on-device. No background sync, no calls home, no graceful-degradation theatre.
01 / 06
Vetted by field experts.
212 entries reviewed by wilderness medics, mountain rescue volunteers, and disaster-relief workers. Sources cited. No AI slop.
02 / 06
Eight real instruments.
Compass, barometer, clinometer, lux meter, SOS torch, decibel meter, plumb line, and a stopwatch — calibrated, not faked.
03 / 06
Offline topo maps.
Pre-load any region as raster + vector tiles. Layered contours, trails, and water sources. No cell service required to view your position.
04 / 06
Proximity mesh chat.

Water
Source-finding, gravity filtration, boil tables, solar still, ice melt, brackish desalination, rationing math.
Shelter
Lean-to, snow trench, A-frame, debris hut, insulation principles, fire reflector walls, hammock systems.
First Aid
Bleeding control, splints, burns, anaphylaxis, hypothermia, frostbite, basic field surgery, CPR cycles.

Disaster Protocol
Earthquake, wildfire, flood, nuclear event, civil unrest — structured response playbooks for each.
Designed for
cold hands
and dim light.
Big targets. High contrast. Step-by-step procedures with diagrams. Every screen is one-thumb operable and stays legible in moonlight, rain, or red-light mode.

The people who'd actually use this.
Early feedback from preppers, outdoor educators, first responders, and parents who take readiness seriously.
“I've used a lot of survival apps. This is the only one I'd actually trust in the field. The offline first approach isn't marketing — it's the whole product.”
Marcus T.
Wildland Firefighter · Montana
“I recommend The Last Manual to every family I work with. The scenario-specific guides are what set it apart. Real situations, real procedures.”
Priya S.
Emergency Preparedness Trainer
“No cell signal for 3 weeks at a time. The compass and barometric monitor alone are worth the price. Everything else is a bonus.”
Dale K.
Backcountry Hunter · Alaska
“The first aid section is actually correct. Most survival apps get medical advice wrong. This one was clearly reviewed by people who know what they're talking about.”
Sarah M.
ER Nurse + Amateur Prepper
“One-time payment for lifetime access. No subscription, no account, no tracking. In 2026 that's almost revolutionary for an app.”
James R.
Ham Radio Operator · Texas
“Earthquake prep is my main concern. The natural disaster module is comprehensive and the checklist builder helped me organize my whole household plan.”
Chen W.
Urban Prepper · California
Be first to know
when we launch.
We ask for two things and nothing else.
So we can reach out like a person, not a bulk mailer. Your first name goes at the top of one email — that's the only place it ever appears.
To send you one message — launch day — with an early-bird discount that isn't available anywhere else. After that, nothing, unless you ask.
We don't sell your data, build ad audiences from it, or share it with any third party. It lives in our launch queue and nowhere else. You can remove yourself in one click at any time.
Straight answers,
no marketing speak.
Eight questions we get asked most. Plain answers, no sales language.
