More and more children have smartphones, but this generation doesn’t know phone numbers by heart anymore. But what if they don’t have their smartphone, but they’re in a situation where they really need to contact you?

Remumber is an app that changes the passcode of your child’s smartphone into your phone number. So instead of entering a random number dozens of times a day, they’re now practising your phone number until they know it by heart.

Together with Missing Children Europe and its member organisations, Remumber was launched in 15 European countries simultaneously. Right before the school holidays, when traditionally more children get lost during their summer activities.
