Calibre Companion

Calibre Companion (CC), recommended by calibre developers, is three applications in one:
Category Price Seller Device
Book $3.99 MultiPie Ltd iPhone, iPad, iPod

- a superb device-based calibre library organiser
- a high-performance WiFi-based calibre device emulator
- a calibre content server and cloud provider client (Dropbox and Microsoft OneDrive)

1) CC is a device-based calibre library organiser. Once you put books on your device using one of the connection methods described below you can:
- view a book's metadata (author, tags, series, rating, dates, etc.).
- sort and group books by their metadata.
- see book lists by cover or by list.
- mark books read and sync this information with calibre.
- launch your book reader application to read a book

2) CC can connect to calibre over WiFi and be detected by calibre as a device. Once connected, you use calibre to move books to and from your device. Calibre automatically updates all the book metadata stored by CC to match the latest in your library.

3) CC can connect to calibre’s content server or to your cloud provider to browse your library and download books to your device. Supports Dropbox and Microsoft OneDrive.

Notes: CC is not a reader app. You must install and use one of the many excellent reader apps available. You must also already use calibre to manage your library of ebooks.



Ads are annoying but paying every month for an app like this is excessive.

Nag screen for an app I paid for

I originally paid for this app and now I’m expected to also pay a subscription fee? You should have launched an entirely new app if you wanted to change your business model.

The Most Useful Tool for E-Book Readers

This application has made it possible to organize my e-books using very useful and customizable categories, upload them into the cloud for on the move reading, convert file formats for my specific needs (e.g., converting PDFs to Kindle formats), etc.

Get rid of the offer to purchase the service!

Please don’t make me have to click past the ad every time I log in.

A gem

I find nothing more frustrating than trying to side load ePub and PDF documents to an Apple device. This app in conjunction with the PC based Calibre system does it easily and quickly. Now I can pursue two of my retirement projects. Read every Weird Tales edition that I have digitized and every copy of my college newspaper (the Cowl)for the years I was there in time for my 50th reunion next year. Thank you.

Keyboard Covers Up Fields/Buttons, No Way to Resolve

When trying to input server data, the keyboard covers up the buttons and fields, preventing you from seeing or selecting covered fields or even clicking ‘OK’ to confirm your entry. Also, unless you’re going to pay a subscription for what largely appears to be an app with the same functionality as the free web page created by Calibre for accessing books on the server (which works great in iOS except for the constant need to re-enter credentials as though I was accessing a financial account), you’ll be confronted with annoying ads for the paid version every time you open the app. I might consider paying if it was a one-time fee, but a subscription model is for me, like with most things, out of the question. I’d rather pay $200 once than $5 per month—I don’t want to have to remember the charge, and I want to have something approximating genuine ownership of the things that I buy.

Should have paid attention to the reviews!

I updated and lost my entire library!

Subscription Methodology

I don’t think subscription is the appropriate model for this app. My stuff is stored in OneDrive, so I view this app as a portal to access my existing content that I could easily just access by opening OneDrive itself. Tweetbot used to do it so you would pay $5 for each new installment of the app (version 2, version 3, version 4) instead of a monthly subscription. I like and appreciate Calibre and hope the devs get paid but that’s just my two cents. I’d gladly pay a $5-10 one time fee every time the app gets a big upgrade. The only thing I don’t like about the app is how I have to tell it to open OneDrive every time I want to reconnect. I only have one library, so I wish it was automatic.


I paid for this app a short while ago. First switching to a subscription model without creating a pro/classic fork like most other apps and now having nag screens to click through in addition to constantly scrolling ads is just too much to deal with. Deleting app and finding a alternative.

Never Used

I bought this app and have never been able to sync with my computer. Not any configuration. Not any troubleshooting step. I keep waiting for updates to fix it but they never come.
