The Problem No One Talks About
In the smartphone age, kids never see or dial actual phone numbers. Everything is "Hey Siri, call Mom" or tapping a contact photo. Speed dial means they never learn the actual digits.
But what happens when your child needs to borrow a stranger's phone? Siri doesn't know who "Mom" is on someone else's phone. If your kid can't recite your number, they can't reach you.
That's a problem worth solving.
The Solution: Make It a Game
Whoya turns phone number memorization into something kids actually want to do. Using proven memory techniques — spaced repetition, active recall, and multi-sensory learning — wrapped in fun games that kids don't even realize are educational.
No nagging. No flash cards. No repeating your number at the dinner table for the hundredth time. Just a phone number learning game that actually works.
How It Works
Add Numbers
Enter the phone numbers your child needs to know — your number, a grandparent, 911. Import from contacts or type them in.
Kids Play
Your child plays fun memory games that practice those numbers. Multiple game modes keep it fresh and engaging.
They Learn
Through repetition and play, they actually memorize the numbers. For real. Even the preschooler.

What age should I teach my child my phone number?
Most child safety experts recommend starting around age 4 or 5 — that's when kids can reliably remember a sequence of numbers. But honestly, there's no wrong time to start. If your 3-year-old is interested, go for it! Whoya makes it a game, so even younger kids can start building familiarity with the digits.
How can I help my child memorize my phone number?
Repetition through play is the gold standard. Songs, rhymes, and games all work. That's exactly why we built Whoya — it uses proven memory techniques (spaced repetition, recall games, and voice practice) wrapped in a fun game kids actually want to play. Way more effective than just repeating the number at your kids over dinner.
What numbers should my child know in an emergency?
At minimum: 911 (or your country's emergency number), and at least one parent's phone number. From there, add a second parent, a grandparent, or a trusted family friend. The free tier gives you 3 numbers — a great starting point for the most critical contacts.
Is Whoya safe for kids?
Extremely. Whoya is 100% on-device — no servers, no tracking, no data collection, no ads, no social features. The only external service is RevenueCat for subscription management, and that only activates if you upgrade to premium. We don't even collect crash reports.
How does Whoya work?
It's simple: add the phone numbers your child needs to learn, let them play fun memory games that practice those numbers, and through repetition and play, they actually memorize them. Multiple game modes keep it fresh, and premium unlocks voice challenges where kids practice saying the numbers out loud.
What's free vs premium?
Free gives you 1 profile, 1 contact list, and up to 3 phone numbers with core game modes — plenty for the essentials. Premium unlocks unlimited profiles (great for siblings), unlimited phone numbers, and all practice modes including voice challenges with on-device speech recognition. Subscriptions are through the App Store, cancel anytime.
Does Whoya collect my child's data?
No. Zero. None. Whoya is built local-only by design. We don't have servers storing your data. We don't use analytics. We don't track taps or screens. If you use the free tier, there's literally zero external service interaction. Even voice challenges process audio entirely on-device. Your child's data never leaves your phone.
Do kids really need to memorize phone numbers in 2026?
More than ever. In the smartphone age, kids never see or dial actual numbers. Everything is speed dial and voice assistants. But if your child gets separated from you and needs to borrow someone's phone — Siri on a stranger's phone doesn't know who "Mom" is. Knowing your actual phone number could be the difference between a scary 20 minutes and a quick phone call.
