VaultMe
A private home for unreleased music: artists keep every version of every song, play them anywhere, and share them with links they control.

VaultMe is my own product, and I'm its first user. As an artist I had unreleased songs scattered across voice memos, cloud folders and message threads, and every time I sent a demo to someone I lost track of where it went. VaultMe gives those songs one private place to live.
It's built to feel like your own music app rather than a file locker. Songs live in projects, each with its full version history, and you can switch between two versions of a song at the same second while it plays to hear exactly what changed. There's a full-screen player with a waveform, a queue, lock-screen controls, and offline listening in the iPhone app, so your vault still plays with no signal.
Sharing is where it differs most. Every song or project can be shared with a private link, with an optional password and downloads switched off by default. You see who opened a link, which songs they played and how far they got, and you can revoke a link the moment you change your mind.
Behind the scenes, files upload straight to private cloud storage in chunks, so a weak phone connection doesn't lose a large WAV. Each upload is checked, turned into a streaming copy and a waveform, and only ever played through short-lived signed addresses: nothing has a public link. The same app runs on the web and as a native iPhone app with Sign in with Apple, and it's now available in the Apple App Store give it a try.
