Read full description

Your audiobooks live on your NAS, as M4B or MP3. CLAUDIO plays them with chapters, stops at the end of a chapter with the sleep timer, and picks up right there the next evening. I build CLAUDIO on my own, so let me be up front about what is in which tier: CLAUDIO Ultra, a subscription that includes Pro, connects your NAS and other servers. Chapters, the sleep timer and the other listening features are also available as a one-time purchase, CLAUDIO Pro. To get both without a subscription, buy CLAUDIO Pro+ once. START FREE • Play music and audiobooks from local files and iCloud Drive. • Subscribe to and stream podcasts by URL or Apple Podcasts search. • Organize with Favorites and Smart Lists such as Recently Added, and use Shuffle and Smart Shuffle. • All themes, including the high-contrast one. LISTEN BETTER - CLAUDIO PRO, ONE-TIME Buy once, no subscription. • Audiobooks: chapters from M4B and tagged MP3, a sleep timer to the end of the chapter or book, playback speed with pitch correction, silence trimming. After a pause, CLAUDIO resumes a few seconds earlier so you don't land mid-sentence. If the sleep timer stopped too soon, a knock resumes playback (Knock to Resume). • Podcasts: download episodes, skip intros and outros, OPML import and export, plus chapters and the sleep timer as with audiobooks. • Music: Album Wall and LP Mode, 10-band EQ, ReplayGain, Gapless, Crossfade, Stereo Widening, volume normalization, animated visualizers and synced lyrics. Scrobbling to ListenBrainz and Last.fm. • Read along: downloaded audiobooks and podcasts are transcribed on device in supported languages, and the text follows the audio. • Widgets for the Home Screen and Lock Screen, controls for Control Center. MATCH YOUR HEADPHONES Pick your model from more than 6,000 headphones, and CLAUDIO builds the matching EQ curve from the open AutoEq measurement data. Listening to it is free; saving it takes CLAUDIO Pro. CLAUDIO ULTRA - MONTHLY OR YEARLY Ultra connects every self-hosted source: NAS/SMB, Jellyfin, Audiobookshelf, Subsonic and Navidrome, DLNA, WebDAV and SFTP. While active, Ultra includes everything in Pro. • Offline cache and pinning: download titles from your server and listen without a connection. • CarPlay for downloaded and local titles. • Send local and downloaded files to Google Cast, DLNA/UPnP and Sonos. • Favorites that sync with Navidrome, Jellyfin and Audiobookshelf. • Statistics and background library refresh. The first scan of a large library takes a while. It keeps running when you leave the app. OWN IT FOREVER - CLAUDIO PRO+, ONE-TIME Don't want a subscription at all? Pro+ unlocks Pro and Ultra permanently with a single purchase, every remote source included, with no recurring payment. Pro+ can be shared through Family Sharing. Existing owners of the former CLAUDIO Pro one-time purchase already have Pro+ automatically. 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 NAS/SMB, Jellyfin, iCloud Drive, RSS feeds or Apple Podcasts search. The App Store privacy label reads "Data Not Collected". MADE BY ONE PERSON Email me a bug or a request. I read everything myself and always reply. 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.

About

BookThread

Features
Read full description

Some books change you. Most of those moments slip away. BookThread is where you catch them — the quote that stopped you cold, the thought you had at 2am, the page you photographed because you couldn't put it into words. Every book gets its own thread, and every thread becomes something you'll actually want to revisit. Add thoughts as they hit you. Pull quotes with beautiful typographic formatting. Drop in photos of dog-eared pages, GIFs, or a quick post. Already read on Kindle? Import your highlights in one tap instead of retyping them. Track where you are with a simple reading status — TBR, Reading, On Hold, Completed, Dropped — right alongside your notes. Add a widget to your home screen and the next thought is one tap away, no need to even open the app first. Everything stays yours. No social feed, no algorithm, no audience — just a private, beautifully kept record of what you read and how it made you feel. Your books deserve more than a star rating and a forgotten shelf. They deserve a thread. Features: - Four entry types: Thought, Quote, Photo, Post - Add GIFs - Add tags and star ratings - Reading status tracking (TBR, Reading, On Hold, Completed, DNF) - Export thread as HTML file - Lock screen and Home screen widget for quick capture - Full iCloud sync across devices - Customisable fonts and dark mode - Private - your threads, no audience - Import Kindle highlights (Beta)

Verdict

The call
