Kivuno

Kivuno helps parents set healthy screen-time limits their kids actually earn — by answering real questions across 16 school subjects, from Grade 1 through Grade 7. How it works: you set a daily time budget for each child. When it runs out, the screen locks. To earn more, your child answers questions in whichever subjects you've turned on for them — math, reading, science, history, and more — at the grade level you set. Correct answers earn minutes back. Built for parents, not for tracking kids. Kivuno works entirely offline. There's no account to create, no ads, and no data of any kind leaves your phone — see our privacy policy for the full detail. A parent PIN keeps settings, subjects, and time limits out of a child's reach. Parent tools include: - Per-child daily time limits and subject selection, by grade - A dashboard showing progress, streaks, and earned badges - The option to block specific apps completely, separate from the earned-time system - Battery and reliability safeguards so the lock keeps working even if your phone's battery-saving settings would otherwise interrupt it Kivuno is designed for the "hand the phone to your kid for a while" scenario — not a permanently kid-owned device — and works entirely without an internet connection.
