Whoosh! app icon: Puff, a smiling white cloud Whoosh!

The calm-down app kids actually ask for.

Big feelings? Whoosh them away.

Meet Puff, a squishy little cloud buddy whose whole world runs on your child's breath. Kids blow on the phone to light candles, float balloons and chase away storm clouds, and every game is secretly a real calm-down breathing exercise.

Try it

Blow out Puff's candles

Hold the button, or press and hold the space bar, and give the cake one big, slow blow. In the app you blow on the phone instead. No microphone needed here.

Five candles to go. Take a big breath in, then hold the button!

Tap and hold, or hold Space.

How it works

Three little steps to calmer

No reading, no sign-up, no tricky menus. Just Puff, a feeling, and a breath.

  1. Check in with your weather

    Each day Puff asks, "How's your weather?" Your child picks the weather that matches how they feel inside, and Puff turns into it.

  2. Play a breathing game

    Puff suggests a game that fits. Blow on the phone to blow out candles, fill balloons or chase storm clouds away. Every breath makes something happen.

  3. Feel calmer

    Sessions are short, one to three minutes. The long, slow breaths do the quiet work while it just feels like play, and then your child puts it down.

How's your weather today?

  • Stormy
  • Rainy
  • Foggy
  • Wiggly
  • Sunny
  • Sleepy

There are no wrong answers. Naming a feeling is the first step to handling it, and a feeling that has a name feels a little smaller.

It knows blowing from talking

Whoosh! listens for the sound of a breath, right on the device, and ignores chatter, giggles and the TV. No microphone, or you would rather not use it? A hold-to-blow button does the same job.

Eight breathing games

Every game hides a calm-down technique

Kids see candles, balloons and fireflies. Underneath, each game guides a different breathing pattern.

For grown-ups

Why parents love it

A tiny tool for the big moments: meltdowns, worries, wiggles and "I can't fall asleep".

Self-regulation, learned by playing

Naming a feeling as weather gives kids words for it, and breathing gives them something to do about it. Kids start to reach for the skill on their own.

A bedtime that winds down

Bedtime with Puff strings two sleepy breathing games together, then turns into a soft night light with a sleep timer, so the whole house can shift into sleepy mode.

Short sessions, not a screen sedative

Sessions are one to three minutes by design. Whoosh! is made to be used for a moment and put down, and a play-time limit in the grown-ups zone keeps it that way.

Calm Insights Plus

See streaks, minutes breathed, how feelings change over time, and the mood lift from before to after play. It lives in a grown-ups zone behind a parental gate, along with settings.

A little science, said carefullySlow, extended exhales are a common part of calming exercises, because they are linked with the body's relaxation response. Whoosh! turns that idea into play. It is a playful tool, not a medical treatment, and not a substitute for professional care.

Privacy promise

Made for kids. Private by design.

We built Whoosh! the way we would want an app for our own children to be built.

  • The microphone stays on the device

    Whoosh! only uses the microphone to detect breath, right on the phone. Audio is never recorded, stored or sent anywhere.

  • No ads

    No banners, no pop-ups, no sneaky videos between games.

  • No tracking

    No analytics or ad SDKs watching what your child does.

  • No accounts

    No sign-up, no email, no password. Open the app and play.

  • No data collection

    Check-ins and streaks stay on your device and go away when you delete the app.

Questions

Good questions, straight answers

Does it record my child?

No. The microphone is only used to detect breath on the device, in the moment. Audio is never recorded, stored or sent anywhere. Whoosh! has no accounts and collects no data.

Does it need internet?

No. The games, Puff and the breath detection all run on your device. You only need a connection to start or restore a purchase through the App Store or Google Play.

What ages is it for?

Whoosh! is made for ages 3 to 8. There is no reading needed, so little ones can play, and the youngest are happiest with a grown-up nearby.

What if we don't want to use the mic?

That is fine. Every game has a hold-to-blow button that does the same job. Press and hold it to blow, let go to rest. It also works if the microphone isn't available or permission is switched off.

How does it tell blowing from talking?

Breath has a distinct, airy sound. Whoosh! listens for that pattern on the device, so chatter and giggles don't move the candles. Breath detection can't be perfect in every room, which is another reason the hold-to-blow button is there.

Is it a medical treatment?

No. Whoosh! is a playful tool, not a medical treatment, and not a substitute for professional care. If you are worried about your child's health, feelings or sleep, please talk to a doctor or a qualified professional.

What do I get with Whoosh Plus?

All eight games, Bedtime with Puff and its night light, Calm Insights for grown-ups, and every Puff colour and hat. Choose monthly ($4.99), yearly ($34.99, with a 7-day free trial) or a one-time lifetime purchase ($59.99).

Ready to whoosh?
