Built specifically for Samsung’s latest foldable, the open-source Foldman (retro Walkman) app transforms the Galaxy Z Fold 8 into a miniature, software-driven portable cassette player with a startling attention to physical detail.
When closed, the app utilizes the device’s cover screen by aligning a miniature cassette tape behind a narrow window, accompanied by playback keys and a volume slider running cleanly down a silver edge-to-edge strip.
It looks remarkably convincing in the hand, recalling the tactile satisfaction of an old Sony device before digital compression stripped our music of its physical weight. But the real engineering trick happens the moment you unfold the phone.
The interface pivots into a full horizontal deck layout, positioning vintage VU meters and a mechanical tape counter alongside your music library and custom album art printed right onto the cassette label.
Prop the phone half-open on a desk, and the deck occupies the top half of the screen like a retro radio sitting. What sets this project apart from standard skin-deep novelty apps is the sheer fidelity of its simulation.
The cassette reels do not just spin at a uniform clip; they rotate according to actual tape physics, accelerating as the virtual spool empties just like a real magnetic ribbon winding across a metal head, as shown by u/Time_Concert_1751/Reddit (via 9to5Google).

The playback keys latch physically into position, fast-forwarding blurs the spinning spools, and stopping the track lets them coast to a natural halt before a satisfying mechanical auto-stop thunks at the end of the side.
Foldman app supports local file formats including MP3, FLAC, and M4A, handles direct Apple Music streaming within the interface, and integrates with YouTube Music by functioning as a remote control for the native app.
Anyone holding an iPhone Duo foldable is going to miss out on one of the cleverest software releases. The first Apple foldable is on sale, but strict sideloading hurdles mean such apps will remain exclusive to Android for the foreseeable future.
If you are daily-driving a Fold 8, grab the APK, drop in your favorite lossless files, and enjoy a brilliantly crafted slice of pocket-sized retro engineering.
