KomiX makes organising your comics as fun as reading them! Features - *See your collection as thumbnails, pinch to zoom making the thumbnails as large or small as you like. *Create “stacks” of comics, in which you can drag and drop sets of comics. *Create “stacks” within stacks, for example you can create a Spider-Man stack, and inside that create a stack for the Amazing Spider-Man, and a stack for the Spectacular Spider-Man, and so on! *Currently reading panel shows you the comic you were last reading so you can jump straight back into it with a tap! *In comic reading view if you tap in the center the HUD will appear, with a thumbnail of each page. You can tap a page to jump to it. *Reads most Comic Book files - cbz, cbr, pdf. *A trash can - drag and drop comics onto the trash can icon to delete them. *An exporter - drag and drop comics onto the exporter icon to package comics to send them to other devices. When comics are packed ready to send the icon will display the number of comics ready, just tap the icon to display the list of ready comics and then tap the export button. *A 'take out of stack' icon - drag comics you want to take out of their current stack and drop them on this icon. *Comic Database feature - can create a Database of all your comics in KomiX, all entries fully editable. You can even add your' physical copy' comics to the Database. The Database has great search features. *Persistent zoom - you can turn on persistent zoom in the settings, good if you use a smaller device (iPhone), and not an iPad to read your comics. *Edit pages - you can now rearrange pages, or delete unwanted or duplicate pages. Tip - you can easily drag more than one comic at a time - start a drag by touching a comic for a second until it 'pops out' then drag it across the screen - don't let go! Now you can tap other comics with a free finger - these will be added to the drag list. Now you can drag the comics to a stack, or the trash, or another App! I hope you enjoy the App! I am a huge fan of comics, so I made this App because I wanted features that other Comic Readers didn't have. Please let me know of any features you'd like via my FaceBook page (reachable in the App).

Pageo is a Calibre companion app for iPhone and iPad: a Calibre ebook reader that syncs your library over Wi-Fi in both directions, converts any ebook to EPUB and reads your books aloud in 31 languages. It connects directly to the Content Server built into Calibre — no cables, no account, no hassle. ▶ TWO-WAY CALIBRE SYNC Turn on the Content Server in Calibre (Mac, Windows or Linux) and Pageo finds it on your local network, or connect by address. Books come to your iPhone or iPad — and your reading position, finished books, ratings and highlights go back to your computer, into Calibre's own annotations. Download one book or the whole library in a tap. ▶ ALL YOUR CALIBRE LIBRARIES — EVEN WITH YOUR COMPUTER OFF Multiple Calibre libraries: browse one at a time or all at once, with separate progress for every book. Or open a Calibre library folder straight from iCloud, Dropbox or this device — no server needed. ▶ PICK UP WHERE YOU LEFT OFF With Pageo Pro, your place, bookmarks and highlights follow you between iPhone and iPad through iCloud — with or without Calibre. Just add the same book on each device. ▶ BUILT FOR CALIBRE POWER USERS Table view puts the columns you built in Calibre into a desktop-style layout — sort by any column, pin titles, jump with the A–Z rail. Search your whole library with Calibre's own search syntax, or search inside every book, even ones you haven't downloaded yet. Series, tags and the author sort you set in Calibre carry over. ▶ CONVERT ANY EBOOK PDF, MOBI, AZW, AZW3, FB2 and CBZ/CBR comics become clean EPUBs right on your device — no desktop, no extra apps. A PDF's footnotes move to the end of the chapter, a tap away from their number. Anything Pageo can't convert itself, it hands to your Calibre server. Share a web page from Safari and it becomes a clean EPUB on your shelf. ▶ READ YOUR WAY Any iOS typeface or reading aids like OpenDyslexic, Atkinson Hyperlegible and Lexend. Focus Text, word spacing and hyphenation in your book's own language. Text up to 400%, six line-spacing and six margin settings. Light, dark and sepia themes, page or scroll mode, page curl or instant turns, right-to-left languages. Tap a picture to see it full screen and zoom in. Highlights, notes and bookmarks — export your annotations to a single file. Pageo remembers your place in every book. ▶ LISTEN TO YOUR BOOKS Turn any ebook into an audiobook with built-in read-aloud: ten lifelike voices, 31 languages, fully offline after a single download. The page follows the voice, and every language gets a natural pace. ▶ FIND ANYTHING FAST Search inside the book you're reading or across your whole library. Your books, chapters, highlights and bookmarks show up in Spotlight, and Siri Shortcuts let you say "Continue reading in Pageo" or "Listen to my book in Pageo". Home Screen widgets keep your current book and reading streak in view. ▶ YOUR LIBRARY, YOUR CONTROL Import from Files, Dropbox, OneDrive or iCloud Drive. Organize by author, series, tags or collection. Nothing to read yet? The Discover tab offers free public-domain classics from Project Gutenberg in many languages. Your books stay on your device — no account, no lock-in. ▶ FREE WITH OPTIONAL PRO UPGRADE Pageo is free to use with ads. Pageo Pro unlocks read-aloud, the converters and iCloud sync, and removes ads. Try Pro free for 3 days. ▶ COMMON QUESTIONS Does Pageo work with Calibre? Yes — with the Content Server built into Calibre on Mac, Windows and Linux. No plugin or connector to install. Does my reading sync between iPhone and iPad? Yes — through iCloud with Pageo Pro, or through Calibre. Does my computer need to be on? For server sync, yes. For a library folder in iCloud or Dropbox, no. Does reading progress sync back to Calibre? Yes — position, finished status, ratings and highlights. Do I need an account? No. Terms of Use (EULA): https://visioncraft.es/pageo-terms Privacy Policy: https://visioncraft.es/pageo-privacy-policy

Verdict

The call

The clearest difference is price: Calibre ebook reader at Free against KomiX's $1.99. Calibre ebook reader also leads on rating (4.7 vs 2.8) and update cadence (every 9 days vs every 2 months). KomiX's advantage is in-app purchases (none vs 4) and ads (none vs shown). On ratings volume and device support there is nothing between them.
