Virtual Pocket Air Conditioning
An air conditioner hum, in your pocket.
Virtual Pocket Air Conditioning turns your phone into a pretend air conditioner. Press the power button and the hum of an AC unit fades in, with cool air waves on screen. It does not cool anything, but plenty of people sleep better with that sound in the background. Built as a fun project to study animations in Flutter.

What it does
Simple premise. Real value.
AC sound
A looped air conditioner hum that fades in when you turn it on and fades out when you turn it off.
Wind animation
The AC pulses and cool air waves drift across the screen while it runs.
One button
Power on, power off. Nothing else to configure.
Nothing collected
No ads, no account, no internet access. The only permission keeps the sound playing.
The story behind it
The Problem
I couldn't sleep without background noise. Air conditioning units are expensive and not always available, so I built a virtual one.
What I Built
A small Flutter app that plays a looped AC ambient sound. The project also served as a sandbox for experimenting with animations in Flutter.
What I Learned
The apps users keep are the ones that do one thing extremely well. No feature creep needed.

A virtual air conditioner in your pocket: one button, a wind animation and the continuous hum of an AC unit.
