About

Tranzit

Read full description

You say "five more minutes." They nod. The timer hits zero. The screen goes dark. And somehow — every single time — it's a surprise. The negotiating starts. The meltdown follows. And you end up the villain again. It's not defiance. For kids with ADHD, time blindness is real — their brain genuinely doesn't feel minutes passing. An abrupt ending doesn't feel like a timer running out. It feels like an ambush. That's what Tranzit is built for. HOW IT WORKS Tranzit runs on a separate iPhone or iPad — a companion device that sits next to your kid while they play or watch. Pick a screen time length, optionally pick what your kid’s transitioning to next, and tap start. From that moment on, Tranzit quietly does the work of making "time's up" stop being a surprise: • A calm voice announces checkpoints ("ten minutes left… five minutes left…") • The screen shifts from green to yellow to red as the clock winds down • At zero, Tranzit announces the end and beeps until you cancel Your kid's brain gets the runway it needs to land on its own — so by the time the screen goes dark, the transition has already happened. WHO IT'S FOR Tranzit is designed for families with kids ages 6–12, where screen-time transitions are often hardest. Tranzit especially resonates with families affected by ADHD or time blindness — but plenty of neurotypical kids can benefit too. WHAT YOU NEED • A spare iPhone or iPad (old ones work great) • Nothing else — Tranzit runs fully on-device, no internet required WHAT YOU GET • Progressive voice warnings with multiple voice options • Green → yellow → orange → red screen that's visible from across the room • Biometric lock so the timer can't be cancelled mid-session by curious hands • One-time purchase — no subscription, no ads, no trackers • Private by design — your settings and session history stay on your device A GENTLE NOTE Tranzit is a tool, not a replacement for parental judgment or professional advice. It's not a medical device. It's the scaffold a lot of families wish they'd had years ago — a structured hand-off that turns "time's up" from an ambush into a landing. Tonight could be different.
