ABC Kids

How it works
  1. Allow the microphone when asked. Use a quiet room.
  2. Hold the phone about 15–20 cm from your mouth — not too close, not too far.
  3. While recording, watch the level bar: keep it in the green zone.
  4. Tap Record → tap again to stop → Play to listen → Save. Not happy? Record again.
