How long would your supplies last?
Most of us have no idea whether what’s in the cupboard would last three days or three weeks. PrepGuard works it out. You add what you have and see, in days, how long it lasts for everyone in your household.
What’s still missing is listed underneath, plainly: 6 litres of water, porridge oats, a few batteries. The yardstick is the authority’s recommendation – in Germany, the BBK’s, the Federal Office of Civil Protection.
- Water by age: 1 to 2 l a day
- Goals from 3 to 30 days
- Scan a barcode or add by hand
