## What is CLAUDIO?

I build CLAUDIO on my own, for people who keep their own audio: the audiobooks, podcasts and music you actually own, in one player that keeps to itself.

START FREE
• Play music and audiobooks from iCloud Drive and local files.
• Subscribe to podcasts by URL or Apple Podcasts search.
• Organize with Smart Lists such as Recently Added and Favorites, and use Shuffle and Smart Shuffle.

MATCH YOUR HEADPHONES
Pick your model from more than 6,000 headphones and CLAUDIO builds an EQ curve tuned to it, based on the open AutoEq measurement data. Browse and audition any tuning for free; save your matched curve with CLAUDIO Pro.

LISTEN BETTER - CLAUDIO PRO, ONE-TIME
Pro is a single purchase, not a subscription. It unlocks the listening features for every source.
• Audiobooks: M4B and tagged-MP3 chapters, chapter navigation, a sleep timer, adjustable speed.
• Podcasts: OPML import and export, plus the same chapters and sleep timer.
• Music: Album Wall and LP Mode, 10-band EQ, ReplayGain, gapless, crossfade, stereo widening, volume normalization and animated visualizers.
• Read along: downloaded audiobooks and podcasts are transcribed on device, so the text follows the audio. Music gets synced lyrics.

CLAUDIO ULTRA - MONTHLY OR YEARLY
Ultra includes Pro while active and connects every self-hosted source: Jellyfin, NAS/SMB, DLNA, WebDAV, SFTP, Subsonic/Navidrome and Audiobookshelf. It adds offline caching and pinning, CarPlay for downloaded and local titles, statistics and background library refresh. If you run your own server, this is the tier for you.

PRIVACY
No CLAUDIO account. No ads. No analytics SDKs. No telemetry. Your library, playback history and podcast subscriptions stay on your device. The app connects only to the sources you choose, such as Jellyfin, NAS/SMB, iCloud Drive, RSS feeds or Apple Podcasts search. The App Store privacy label reads "Data Not Collected".

MADE BY ONE PERSON
CLAUDIO is a solo project. Email a bug or a request and I read it myself, and usually answer. The Discord link in Settings is open to everyone.

CLAUDIO Ultra is an optional auto-renewable subscription (monthly or yearly). It includes Pro while active and unlocks all remote sources, offline caching, statistics and CarPlay for downloaded and local titles. Cancel anytime in App Store Settings. Payment is charged to your Apple ID. Auto-renews unless canceled at least 24 hours before the end of the current period.

OWN IT FOREVER - CLAUDIO PRO+, ONE-TIME
Don't want a subscription at all? Pro+ is a single one-time purchase that unlocks Pro and Ultra permanently - every remote source, offline caching, statistics and CarPlay for downloaded and local titles, with no recurring payment, ever. Existing owners of the former CLAUDIO Pro one-time purchase already have Pro+ automatically.

### 3/5 — Ich weiß nicht

*2026-05-22*

Etwas durchwachsen, habe mal die Pro gekauft um dann festzustellen, daß mein Musicfolder auf dem Syno mit einem Fehler den Scan abgebrochen hat. 
CarPlay nur im Abo.
Denke das war ein Griff ins Klo.
Infuse , VLC kann das.

**Developer response:** Hi! Lass mir gerne den Fehler an support@nerdwana.net, über die Supportmail hier im AppStore oder am besten über Discord zukommen Link in der App) - und dann schau ich mir das sofort an! Ich lese alle Nachrichten und gemeinsam können wir das bestimmt lösen! Wer weiß, was sich da für Problemdateien auf deinen Festplatten verstecken haben? 

Ich freue mich über jeden Fehler, den wir finden und beseitigen. Und wer weiß... du hast eine ältere Version verwendet, vielleicht hat sich das Problem ja mittlerweile von alleine behoben? Falls nicht, bekommst du für deine Unterstützung ein Ultra-Abo, versprochen!

## Version history (last 5 releases)

### 13.0 — 2026-08-13

New in CLAUDIO 13.0

New
• Home has been rebuilt: a big highlight up top, then continue listening, recommendations and now single tracks too - sections collapse, recommendations can be removed.
• The player is new: the surface takes on the cover's tone, lyrics and read-along have their own view, and artist and album lead straight into the library.
• On iPad the player gets its own two-column layout.
• The new mini player sits in the tab bar, carries progress as a ring and shows where you are right now.
• A taste profile learns over months what you like to hear, orders Home by it and feeds Smart Shuffle.
• A short tour on first launch shows where things are.

Improved
• Home builds noticeably faster.
• A tidier library: lists and favorites are views instead of separate tabs, the header stays put as you go deeper, covers are bigger and the view remembers where you were.
• Audiobook series show their volume number, and CarPlay makes long episode titles and series readable.
• Favorites and stars from your servers now count in the app too, without writing anything back.
• The app comes back right where you left it.
• Titles you have started now show it in the list.

Fixed
• Played podcast episodes leave the unplayed list even when their duration is unknown.
• Shuffling more than a hundred marked albums now really plays each one once.
• An evening of the same music no longer tips the recommendations in one direction.
• Chapter numbers no longer appear twice.
• When the Ultra pass expires you now find out, instead of it lapsing silently.

### 12.0 — 2026-08-10

Neu in CLAUDIO 12.0

Neu
• Eigene Listen: Titel von Hand zusammenstellen und in genau deiner Reihenfolge halten.
• Playlists von Jellyfin, Navidrome/Subsonic und Audiobookshelf - auch Collections - erscheinen als gespiegelte, schreibgeschützte Listen. Duplizieren macht daraus eine eigene, bearbeitbare Liste.
• Import von m3u- und m3u8-Playlists. Einträge, deren Datei noch nicht in der Bibliothek ist, bleiben als Platzhalter sichtbar, statt zu verschwinden.
• Favoriten sind jetzt eine echte Liste statt eines Filters - sortiere sie, wie du willst.
• Eine Liste offline halten und in CarPlay anbieten. Für Ultra.

Verbessert
• Eine gespiegelte Serverliste zieht ihre aktuelle Reihenfolge beim Öffnen nach.

Behoben
• Audiobookshelf-Collections und -Playlists finden ihre Bücher jetzt in der Bibliothek, statt sie als fehlend zu melden.
• Ein Podcast-Download übersteht jetzt, dass der Feed seine Adresse umschreibt.
• Kapitelbilder überstehen den Wechsel vom Stream zum Download.
• Ein wiederhergestelltes Backup macht die Favoriten nicht mehr zum Filter.

### 11.0 — 2026-08-04

New in CLAUDIO 11.0

New
• Read along: the text follows the audio as you listen - word by word or sentence by sentence. It is created right on your device, with no account and no server. For Pro and Ultra.
• Playback bookmarks: mark a spot, add your own note, and jump straight back to it later. They travel with your backup.
• Listening streaks and a history of your listening sessions in Statistics.
• Automatic chapters for files that bring none of their own - switch it on in Settings.

Improved
• Redesigned podcast page: release date, progress and remaining time per episode, download and played right in the row, plus filters for New, Downloaded and All.
• Noticeably lighter on memory, especially with cover art and large downloads.

Fixed
• Playback starts right away, even when the server is currently unreachable.
• A dropped SMB stream now reports the error instead of stalling silently.
• Podcast artwork no longer stays grey, and the first tap on download takes effect immediately.
• Many small fixes to layout, contrast and playback.

### 10.0 — 2026-07-28

New in CLAUDIO 10.0

New
• Discover podcasts by genre - a new genre directory in the subscribe sheet.
• Redesigned podcast page: a clear play action and progress at a glance.
• Every visual theme is now free - including the high-contrast one, now suggested during setup.

Improved
• Statistics moved to the More tab, and chapters now show their progress as a fill bar.

Fixed
• Titles deleted on the server now disappear in the app too - for Jellyfin, Subsonic and Audiobookshelf.
• More stable streaming from SMB and SFTP shares thanks to a persistent per-session connection.
• Podcast pages with very many episodes now open without hanging.
• Many small fixes to layout, contrast and playback.

### 9.0 — 2026-07-21

New in CLAUDIO 9.0

Improved
• Improved playback speed for audiobooks & podcasts — noticeably more natural sound at higher tempos, no more humming/"underwater" artifacts.
• Silence trimming (Smart Speed) now detects pauses more precisely with an adaptive noise floor.

Fixed
• "Skip outro" for podcasts now triggers reliably.
• Chapter artwork no longer disappears when switching tracks quickly.
• Switching tabs no longer hangs in large libraries with many audiobook groupings.
