Notify Sound is a free app to shape custom notification sounds for your mobile phone. Tell your AI assistant, such as Claude or ChatGPT, what you want to hear (a soft two-note chime, a retro coin pickup or an alert that cuts through a noisy room), and it builds the sound layer by layer. It hands you a link that opens the sound in the editor, ready to play and to change. Or start from a sound you like and shape it yourself until it feels like yours.

Every change plays back the moment you make it, so you can soften a ping that feels too sharp, let a bell ring out a little longer or give a chirp a lift at the end. A touch of space around the whole sound makes it warmer.

A single tone can sound thin, so you stack layers for depth: a bright layer above the main note adds sparkle, and a low one underneath adds weight.

When it sounds right, save it or share it with a link. Download it to set it as your notification sound, text tone or ringtone. More than 200 ready-made sounds are there to start from, and no account is needed.
