I built an alarm app where kids roar into the microphone to wake up — and it actually works
Hey IH — dickybuilds here. Some of you might know me from Arise (motivational alarm app I launched here a few weeks ago). I just shipped my second app and wanted to share the story.
The problem
Every morning was the same: alarm goes off, kid ignores it, I walk in 3 times, negotiations begin, tears, eventually dragging blankets off. By breakfast, everyone's angry.
I looked for a kids alarm app and found... nothing. Toddler sleep clocks for ages 2-5, adult alarm apps with math puzzles for 16+. Ages 6-12? A total dead zone.
The solution: Chirpie
An alarm app for kids (5-8) where they dismiss the alarm with physical rituals instead of buttons:
- Nova (Space Explorer) — shake the phone to launch a rocket, spin to orbit a satellite, tilt to dodge asteroids
- Finn (Nature Ranger) — tap to pick flowers, draw circles to wake the sun, catch fireflies
- Roar (Lion) — literally roar into the microphone, bark like a dog, do a cock-a-doodle-doo
Each character has 3 ritual variants that rotate daily. Kids never know what they'll get.
What keeps them hooked
Characters visually evolve at streak milestones. Day 14: tiny cub becomes a young lion. Day 30: King of the Jungle. My test kid hasn't missed an alarm in weeks because she wants the evolution.
Tech stack
Swift + SwiftUI, Apple AlarmKit (iOS 26+), 93 ElevenLabs voice lines + 21 SFX bundled as .m4a, StoreKit 2, zero network calls except StoreKit.
Business model
Free forever with Nova. $4.99 one-time to unlock Finn + Roar. No subscription, no ads, no tracking. Kids Category compliance.
Lessons from launching Arise that I applied
- Price anchor in description ($4.99 once vs $30-50/yr subscriptions)
- Preview Alarm button so reviewers and parents can demo instantly
- Bundle all audio at build time — AlarmKit can't play runtime-copied files
- Fresh UUID every alarm schedule or you get silent failures
The ask
Would love feedback on the listing and marketing ideas. The physical ritual mechanic is inherently shareable — parents filming kids roaring at 7am is TikTok gold — but I'm a solo dev, not a marketer.

Happy to answer questions about AlarmKit, Kids Category compliance, or building a second app on the same architecture!
The streak + visual evolution mechanic is smart — you're not selling an alarm app, you're selling a character arc the kid wants to see play out. The TikTok angle is real but hard to manufacture as a solo dev. One low-effort version: add a share button right at the moment the evolution happens. That's the peak emotion — if the kid just became King of the Jungle, the parent is already reaching for the phone.
