leb is a digital way for elderly and care-dependent individuals and their families to check in. Once a day, users confirm with the touch of a button in the app that everything is alright. Only if this confirmation is missing for more than 24 hours does leb inform the designated contact person via email, SMS, or WhatsApp. leb is not an emergency or alarm system, but a simple and dignified addition to everyday life. It provides security for some and relief for others – quietly, easily accessible, and deliberately uncomplicated.
