How the app works

Supplies and how many days they last

Note what you have at home (and maybe at the cottage): water, food, medicine, batteries… with the expiry date. The app works out how many days you are covered for the number of people in your household. Every person counts, children too (as the official recommendations say). Water: at least 2 litres per person a day (3 l in Poland), food: one day's ration per person.

Colours show what expires soon. Expiry reminders come to your phone (Plus).

What to keep at home

A checklist based on the official recommendations of your country, scaled to your household. Rows come with short guides – what food exactly, what to do when the water stops, what to do without power, first aid, where to find news.

Emergency bag

A bag for leaving home quickly – ideally one for each person, or one for the whole household. The packing list tells you what to pack and you just tick things off; for water, food and medicine the app also watches the expiry dates. A child's bag reminds you of a card with name and contact for the pocket.

Offline map and meeting points

Download a map of your area once (with internet). Then it works without signal. Mark the meeting points – where your family meets if phones stop working. An arrow and the distance lead you there using only GPS and the compass, no internet. Offline maps are available for Czechia only for now.

Screen for children

A large, simple screen: where to go, the arrow, who to call and how to call 112. You write the message for your children yourself.

Contacts and emergency numbers

Phone numbers and addresses of your people, available offline. Emergency numbers for your country with one tap.

Sharing with your family (optional)

Want the whole family to see the supplies, meeting points and contacts? Create a family and invite the others with a QR code.

• No password – an e-mail is enough, we send you a code.
• End-to-end encryption – the family key is only in the invite and on the family's phones. The server sees only encrypted data.
• You approve new members – nobody joins without you.

Free and Plus

The basics are free: supplies, checklist, bags, map, meeting points, arrow, kids screen, contacts, family sharing for up to 4 people. Plus (99 CZK a year in Czechia; the store shows the price for your country) adds unlimited supplies and places, expiry reminders, more maps and a larger family.
