CACHE is a fast and simple sample browser for iPhone, iPad, and AUv3 hosts. It lets you open your own sample folders, browse collections instantly, preview audio files, detect sample key, and drag sounds straight into compatible apps and hosts. Built for producers who work across iOS and iPadOS, CACHE solves a problem that has been strangely overlooked for years: some DAWs and AUv3 hosts still don’t include a proper sample browser. Until now, that often meant digging through Files, switching between apps, and dragging samples in from outside your music workflow. CACHE puts that missing browser exactly where you need it. Use CACHE to: Browse your own sample folders and subfolders Preview one-shots and loops quickly Detect likely sample key for one-shots Drag samples directly into compatible DAWs, hosts, and apps Access collections from local storage, cloud locations, or external drives CACHE does not include any samples and does not make sound on its own beyond sample preview. You must supply your own sample folders. CACHE also does not copy or store your samples internally. It simply bookmarks and browses the folders you choose, so it won’t take up extra storage space with duplicate sample libraries. That makes it especially useful if your sounds live on external storage or outside the app itself.
