Crazy mosquito

Hide your phone next to your friend right now. A mosquito sound is about to kick in.
With 5 different mosquito sounds and a gradual fade-in feature.

That sound you hear by your ear on a summer night right after you lie down to sleep.
That feeling of flailing your hands inside the blanket without even knowing if there's actually a mosquito there.

'Crazy Mosquito' replicates that exact moment, anytime, anywhere.

[5 Types of Mosquito Sounds]
- Normal Mosquito — That most common sound you always hear
- Big Mosquito — A lower, heavier buzzing sound
- Swarm — The sound of multiple mosquitoes circling simultaneously
- Near the Ear — The feeling of it buzzing right next to your ear
- Ultra-high Frequency — A subtle, annoying frequency that's hard to hear but nerve-wracking

Choose the right sound for the situation and blast it at the perfect moment!

[Real-time Volume / Pitch Control]
You can freely adjust both volume and pitch.
If it's too loud, you'll get caught instantly—so start quiet and make it progressively louder.
Lower the pitch for a massive mosquito vibe, or raise it for that high-pitched, infuriating mosquito effect.

[Gradual Fade-In Feature]
The core feature of this app.
When you first hit play, the sound starts at 0 and the volume turns up incredibly slowly.
Manually set the fade-in time anywhere from 3 seconds up to 30 seconds.

[How to Use]
1. Turn Fade-In ON and set the time to 15–20 seconds.
2. Hide your phone in your friend's room (under a cushion, in a desk drawer, inside the blanket, anywhere!).
3. Press the play button and casually walk away.
4. Watch your friend hear nothing at first, and then see their facial expression slowly change.

Because they won't know when the sound actually started, it's way more confusing.

[Recommended for]
- People who want to prank roommates, siblings, or close friends.
- People who want to be the mood maker at camping trips, retreats, or group gatherings.
- People whose hobby is flustering friends over silly things.
- People who want to spread their summer night mosquito trauma to others.
