Question 1

Is Dodo really free?

Accepted Answer

Yes — completely free, forever. No ads, no subscriptions, no in-app purchases, no hidden fees.

Question 2

Why doesn't the mute switch silence Dodo?

Accepted Answer

Dodo uses the media playback audio category (like Spotify or Apple Music). The mute switch is intentionally bypassed so your baby's sleep sound doesn't accidentally stop. Use the volume buttons to adjust loudness.

Question 3

Does Dodo work with AirPlay or Bluetooth?

Accepted Answer

Yes. Start playing a sound, then select your output device from Control Center. Works with AirPods, HomePod, CarPlay and any Bluetooth speaker.

Question 4

Does Dodo collect any data?

Accepted Answer

No. Dodo works entirely offline. No analytics, no tracking, no accounts, no network requests.

Question 5

How does the Sleep Timer work?

Accepted Answer

Tap the moon icon next to the play button and choose a duration (15 min, 30 min, 1 hour, 2 hours). When the timer ends, sound fades out over 9 seconds — gently enough that your baby won't notice.

Question 6

What are Sleep Filters?

Accepted Answer

Built-in EQ filters that reduce harsh frequencies on phone speakers. Calm is a light filter. Sleep is a deep, warm filter ideal for overnight listening.

Question 7

Which sounds are included?

Accepted Answer

Eight sounds: White Noise, Womb Sound, Brown Noise, Pink Noise, Green Noise, Rain, Ocean, and Box Fan.

Question 8

Does Dodo need an internet connection?

Accepted Answer

No. All sounds are generated on-device in real time, so Dodo works on airplanes, road trips, and anywhere with no signal.

Question 9

What does "Dodo" mean?

Accepted Answer

In French, "faire dodo" means "go to sleep" — it's what parents say to babies at bedtime.
