You know this moment.
You’re at dinner. The wiggling starts. You hand over your phone — and ninety seconds later someone has renamed your Wi‑Fi, FaceTimed a coworker, and discovered the camera roll.
iOS Guided Access already solves half of this. Triple‑click, and the phone locks to a single app. Nothing else exists. Nothing breaks.
The other half is the question nobody answers: locked into what? Ondo is our answer — the app worth locking a kid into.
They don’t know they’re learning.
You know they are.
Ondo turns the phone’s own sensors — tilt, motion, microphone, camera, light — into a physics playground. Gravity you can pour. Particles that chase a wave of the hand. Sound made visible. No menus, no levels, no score. Just cause, effect, and delight — the way real learning starts.
Simple, elegant, calming, and charming. The modern parent’s new best friend.
Six little universes.
All included from day one. No unlocks, ever.
Gravity Garden
tilt + shake
Tip the phone and the world tips with it. Planets fall, collide, and settle into orbits. Shake for an asteroid flurry.
Particle Universe
touch + wave
A thousand points of light that chase every wave of the hand and bloom under every tap. Its luminous, living heart.
Sound Storm
microphone
Clap, hum, roar. The phone listens and paints the sound — louder is bigger, higher is brighter.
Orbit Maker
drag + pinch
Fling a moon and watch it swing. Pinch to make it heavy. Gravity does the choreography.
Light Sweep
flashlight + wave
Lights off, flashlight on. Draw in the dark and the trail hangs in the air like a sparkler.
Color Storm
gyro + motion
Pure color, poured. Move the phone and paint flows around you — a water slide you’re inside of. That’s it up top.
One app. It grows with them.
Three modes tune every activity’s speed, sound, and touch to the kid holding it.
Baby · 6–18 months
They watch. You tilt.
Pure sensory wonder.
- Sensor‑driven visuals — no touch required
- Soft colors, gentle sounds, slow drift
- Camera mode on: the baby sees the baby
Toddler · 1–3 years
Tap. Tilt. Giggle. Repeat.
Big, bright cause and effect.
- Tap to create, shake to scatter, tilt to move
- A gentle haptic answers every touch
- Nothing to get wrong — every input delights
Preschool · 3–6 years
First real physics.
Gestures, orbits, tiny challenges.
- Drag orbits, pinch mass, clap up a storm
- Bop‑It‑style mini‑games: shake to launch, tilt to catch
- Camera mode becomes their choice
No accounts, no profiles — the parent picks a mode and hands the phone over.
The kid is the experience.
Flip camera mode on and the screen shows them — with the physics layered over the real world. Particles land on their hands. Their giggle sets off the storm. Kids love seeing themselves, and Ondo makes them the main character.
Babies and toddlers get it by default; preschoolers get the toggle. And the feed never leaves the device — nothing is recorded, nothing is stored, nothing is sent. It’s a mirror, not a camera.
Camera & mic never leave the deviceThe whole app sings in C major.
Every tap, orbit, and splash is a note from one warm bell‑toned instrument, tuned to a single happy key — characterful sounds with real personality, never generic beeps. Continuous play doesn’t make noise; it makes a melody. (Yes, there’s a mute switch.)
Nothing leaves the phone. Nothing.
Not a policy promise — a design constraint. Ondo has no server to talk to.
Zero network calls
Ondo doesn’t talk to the internet. At all. It works in airplane mode — forever, on purpose.
Zero data collection
No analytics, no accounts, no tracking SDKs, no ads. There is nothing to collect and nowhere to send it.
Camera & mic stay on‑device
Frames and audio are processed live and thrown away. Never stored, never uploaded, never analyzed off‑device.
Built for Guided Access
No external links, no store buttons, nothing a small thumb can wander into. Designed to be locked into.
- All six activities included
- All three age modes
- No subscription
- No ads
- No in‑app purchases
You buy a toy. You own the toy. No “premium particles.”
Be first when it’s ready.
Honest status: Ondo is being built right now as a native iOS app, and it will reach TestFlight before it reaches the App Store. There’s no download button here because there’s nothing to download yet. Leave an email and we’ll write exactly twice — when TestFlight opens, and when it ships.
Prefer email? Write to darnell@studioburnside.com and we’ll add you by hand.
You’re on the list.
We’ll email you when TestFlight opens — and once more when Ondo ships. That’s it.
