Clickwheel plays only your own music files: no account, no streaming, no ads, no data collection. The wheel tracks the angle of your finger rather than the distance it travels. Every few degrees it clicks audibly and you feel it, just like on the classic MP3 players. It plays MP3, AAC, FLAC, WAV and AIFF, with lossless files played as they are. The player is free. A one-time €4.99 upgrade adds a tag manager, playlists and five more case colors.
