Yello
Safe, simple calling for kids — controlled by parents
Yello is a VoIP calling app that lets children call a parent-approved list of contacts over WiFi. No phone number needed, no unsupervised access, no surprises.
Parents build a curated contact list. Kids can only call people you've explicitly allowed — no one else.
Big, friendly buttons make it easy for kids to call grandma, dad, or a babysitter with a single tap.
Set time windows when calling is allowed. No late-night calls or early-morning wake-ups.
Optionally limit calling to specific WiFi networks so calls only happen at home or approved locations.
All settings are protected behind a parent PIN. Kids use the app; parents control it.
See a log of every call — who was called, when, and for how long. Full visibility for parents.
