With Kontingent your child manages their own screen time – just like a flexi-time account. You give them trust and strengthen their sense of responsibility, self-determination and a mindful use of screen time. Instead of daily arguments, your child gets a clear time budget and learns to manage it themselves. How it works • Set a daily allowance for each day of the week – for example one hour on weekdays, more on weekends. • Your child starts and pauses their time themselves with a single tap. • Unused time moves to the flexi-time account – saved credit your child can spend freely. • When the allowance runs out, an alarm goes off – with playful, freely selectable ringtones. • The history shows the time used each day. Corrections are made by you, the parent. For parents • PIN-protected parent area. • Flexibly set times, a daily maximum and rules. • A QR code opens your child's view on any device. Fair and privacy-friendly • No ads, no tracking, no hidden purchases. • No sign-up required: we don't collect any personal data from you or your family. Kontingent helps your child learn a self-directed, healthy relationship with screen time.
