CloudSpinner: Spin your records and videos from your personal cloud This app requires you using a third party cloud service as your file storage. It currently supports Dropbox, Google Drive and One Drive. By popular demand, other services can be considered implemented at a later point. CloudSpinner lets you browse, play, and manage your backed-up music, recordings, demos, and videos using cloud services you may already subscribe to. Connect to Dropbox, Google Drive, or OneDrive and browse your existing folder structure directly, treating your cloud storage as a personal media library. The app supports lossless playback when available, stable streaming with low CPU and power usage, and playlist creation across one or multiple cloud services. Tracks and playlists can be downloaded for offline playback and managed locally on your device. CloudSpinner includes a practice mode with adjustable playback speed without changing pitch, useful for rehearsing, learning parts, or working with recordings and demos. Built-in search makes it easy to locate tracks, folders, or albums across connected libraries. A sleep timer can be used for those who fall asleep to sounds playing. Cover art can be auto-scanned and cached locally, or manually selected from public databases. You may also access Discogs and MusicBrainz databases to view track information. Playback continues in the background with lock screen controls. The app supports Apple CarPlay for in-car use. Network usage can be adjusted, allowing you to control Wi-Fi and cellular data behavior when streaming or downloading content. CloudSpinner supports both light and dark mode and follows system appearance settings. CloudSpinner is designed for reliable playback and focused listening, without ads, social features, analytics, or automated content modification. Your rhythm, no algorithms.
