Latin for always ready
Parati Semper turns getting your household ready for an emergency into small, clear steps. It shows what you have, how long it would last, and the one thing to do next.
The name
pah-RAH-tee SEM-pehr
Our mission
Help every household be ready for what comes. Know what you have, how long it would last, and what to do next, one small step at a time, without fear and without giving up your privacy.
What it does
Most people know they should be prepared. Few know where to start, how much is enough, or whether what they have would actually last. Parati Semper answers those questions for your household, in plain numbers.
Keep one list of the water, food, medicine and gear in your home, car and bags, sorted by where it lives. Expiry dates and low stock come to you, so nothing quietly goes bad.
Tell it who lives with you, people and pets. It works out what your household needs each day and turns your shelves into days of water, food and medication, with the shortest one called out.
Every gap is ranked by how much it moves you forward and what it costs. Set a monthly budget and it picks the purchases that matter most, so money goes where it counts.
Checklists for 19 kits, step-by-step plans for 25 situations from a power outage to a hurricane, and 73 skills to practice and log, from shutting off the gas to purifying water.
No account, no ads, no tracking. Everything stays on your devices. Sync through your own iCloud only if you switch it on, and keep an encrypted backup you control.
The journey
A checklist tells you everything at once. A journey tells you what is next. Each rank asks for a little more time on your own, a few more kit items, one more skill and one more plan, and you can see exactly what is left before the next one.
Flame, three days on your own, is the 72-hour standard FEMA and the American Red Cross ask every household to meet.
A week with Parati Semper
Follow one household, Ana, Tom, their two kids and Rufus the dog, from the first evening to the morning after a storm.
Sunday evening · 15 minutes
Ana adds the four of them and the dog, then the water and food already in the pantry. The app does the math: 5.2 days of water, 8.2 days of food, a month of her daily medication.
What the app doesRanks them at Spark, flags water as the shortest supply, and names one next step: a lantern for the room they gather in.
The first of the month · 2 minutes
They set aside $120 a month. Instead of a cart full of gear they may never use, the app lays out this month's purchases in order of how far each one moves them.
What the app doesRanks every gap by impact per dollar and builds a shopping plan that fits the budget, with the rest waiting for next month.
Saturday at the store · 30 seconds
Tom brings home a 55-gallon water barrel. He adds it where it lives, in the basement, with the date to rotate it.
What the app doesWater coverage jumps from five days to more than two weeks. With reminders on, a nudge comes a week before the water is due for rotation.
Wednesday after dinner · 20 minutes
Around the table they write the 60-second escape plan: who wakes whom, which window, where to meet. On Friday night they run the drill in the dark and fix the window that sticks.
What the app doesTurns the plan into steps they can check off, logs the drill as practice, and moves them toward the next rank.
A rainy weekend · one project
The lesson survivors of Hurricane Katrina repeated most: the house could be replaced; the photos and papers could not. Ana gathers birth certificates, insurance, the medication list and the family photos into one bag by the bed.
What the app doesWalks through every document worth saving, tracks what is packed, and keeps the bag's weight under 20 pounds.
Thursday · a hurricane watch
The forecast puts their town in the cone, two days out. They do not wait for an order. They open the twelve-hour pack-out and work down it: fuel, cash, medications, the house shut down, a sign on the door.
What the app doesGives one plan at three speeds, sixty seconds, one hour and twelve hours, so the steps are written before the stress arrives.
The morning after · under an hour a day
They are safe at Tom's sister's house. Now the work starts: family, employer, disaster assistance, the insurer, the mortgage. It is overwhelming until it is a list.
What the app doesRuns the day-after plan as a short daily loop, from the first call to the road back home.
Any time · no signal needed
How long to boil water. How many drops of bleach per gallon. How long the freezer stays safe. The guidance lives on the phone, not on a website you cannot reach.
What the app doesKeeps 47 plain-language articles from FEMA, the American Red Cross and the CDC fully offline.
Three months in
A little each week added up. Seventeen days of water, nineteen of food, every kit nearly full, and a plan for the storms that matter where they live.
What the app doesRanks them at Flame, the 72-hour standard and more, with the next rank in sight.
Built on public guidance
Every checklist, calculation and article is drawn from public guidance: FEMA's Ready.gov, the American Red Cross, the CDC and the USDA, the Mifflin-St Jeor equation for calorie needs, and lessons written by survivors of Hurricane Katrina. Nothing is a guess, and nothing is sold to you.
Privacy
What you store, where you keep it and how you would leave is exactly the information that should stay private. So we never see it.
Open the app and start. There is nothing to sign up for.
No analytics, no ads, no tracking. The app collects no data at all.
Records stay on the device. Sync across your iPhone, iPad and Mac through your own private iCloud, only if you switch it on.
Export everything to one file, protected with a passphrase if you like. Lock the app with Face ID.
Parati Semper is coming to the App Store for iPhone, iPad and Mac.
Light and dark, at home on every screen.
Questions
It is for any household. The first ranks are the basics FEMA and the Red Cross recommend for everyone: a few days of water and food, a first aid kit, a plan and a meeting place. If you want to go further, the later ranks are there when you are.
No. Everything, including the articles, works without a signal. The internet is only used if you switch on iCloud sync.
Water follows the Ready.gov standard of one gallon per person per day, plus a little for pets. Calories use the Mifflin-St Jeor equation from each person's age, height, weight and activity, with a 2,000-calorie baseline for children.
Today, sync keeps one person's iPhone, iPad and Mac in step. Sharing one household between people is the next feature we are building.
Without iCloud sync, it is gone with the app, which is why there is a one-tap export. With sync on, it stays in your private iCloud until you remove it.
No. It is educational guidance summarized from public sources. Take a certified first aid and CPR course, and follow local authorities during an emergency.
