Kasset: Music & Audiobooks

Offline player for your files

Free · In‑App Purchases

New in 0.5: Siri, playlists sent to a phone nearby, and Kasset Pro in the car. Drop in a folder of music or audiobooks and it's a playlist. No ads, no account. The music is already on your phone. Finding an app that will simply play it is the hard part — everything wants an account, a connection, a subscription, and an ad between the tracks you own. Kasset plays your files. Copy a folder of audio onto your iPhone or iPad and it becomes a playlist. An audiobook remembers where you stopped. There is nothing to sign into, and your library never leaves your device. FOLDERS IN, PLAYLISTS OUT - Drop folders into On My iPhone → Kasset from the Files app or a Mac, or send them from any computer's browser over Wi-Fi. Every folder becomes a playlist. - Or add a folder from anywhere else: iCloud Drive, a USB stick, another app. - Plays MP3, AAC, M4A, M4B, ALAC, FLAC, WAV, AIFF and CAF, and reads M3U and PLS playlists. - Albums play straight through, with no gap between songs. Each song is listed once, even when a folder holds two copies. - Sort by date added, search and reorder. Share a playlist as one folder, or send it to a friend's phone nearby with a code. IN THE CAR, ON YOUR WRIST, BY VOICE - CarPlay: your playlists, books and recent plays. Pick any song; a book picks up where you left it. - Siri: "Play Morning Coffee in Kasset", "Resume my book in Kasset". - Apple Watch: start a playlist or a book from your wrist. iPad: the player beside your library. - A Home Screen widget with play, pause and next. AUDIOBOOKS THAT KEEP THEIR PLACE - Every book keeps its own place, so music in between never loses it. - Chapters inside one file, or a folder of parts. - 15 seconds back and 30 forward, speed from 0.75x to 3x with the voice unchanged, and a sleep timer. - A book pauses while your navigation speaks. FREE AUDIOBOOKS FROM LIBRIVOX - Classics read by LibriVox volunteers and kept by the Internet Archive, in English, German, French, Spanish and Portuguese. - Hear a chapter first, then add the book to your library: it keeps its place, plays offline and shows in CarPlay. IT MOVES WITH THE MUSIC - Four visualizations drawn from the sound itself: Spectrum, Scope, Orbit and Aurora. Nothing strobes, and Reduce Motion is respected. - Covers for songs with no artwork, made on your device: by Apple Intelligence where it is on (iOS 18.4 to 26), painted from the song's own sound everywhere else. Artwork in your files always wins. SOUNDS THE WAY YOU LIKE - A ten-band equalizer with ten presets, on AirPlay and CarPlay too. - Lyrics from .lrc files or tags, synced and tappable, where the cover was. Online lookup stays off until you turn it on. - Lock screen, Control Center, headset buttons and AirPlay. KASSET PRO, ONE TIME An optional one-time purchase adds: - In the car: Most played, Recently added, Forgotten favorites and Moods at the top of your playlists. - Every Shuffle is Smart shuffle, flowing by energy, and even loudness is on from the start. - An equalizer per playlist and per output: the car, your headphones and a speaker each keep their own sound. Crossfade too. - Smart and mood playlists, and your year in listening. - Cassette and retro players, also as widgets, and five more color themes. - Auto lyric sync on the device, a tag editor, and lyric timing that saves .lrc files. - For books: skip silence, voice boost, smart rewind, and bookmarks with notes. FREE. NO ADS. NO ACCOUNT. NO SUBSCRIPTION. - Everything above Kasset Pro is free, and stays free. Kasset Pro is a single purchase. - No account, no cloud, no analytics. The App Store privacy label reads "Data Not Collected". Kasset plays the files you already have, and the free audiobooks you add. No streaming, no ripping. Questions? support@suprun.ca
