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.

Even as a free version user, I find this app very helpful for accessing my Dropbox-stored libraries. It takes advantage of some of the primary advantages I see to using Calibre, including tag searching and cover display. The biggest complaint that I would like to request some attention to is whatever goes on while the app is in the background. I’m usually using my Calibre libraries during research, which often requires juggling multiple apps. When in the background, The app resets to the home screen and disconnects from my cloud server. You can imagine how annoying this is. I do also have two feature requests. I have two libraries in Dropbox. It would make more sense to me to select which library to connect to from the home screen, rather than connecting and loading a library & then having to switch. This seems counterintuitive, and I am constantly hunting for this selection. There’s also a bug of some sort that always indicates the library I want (but which isn’t currently connected) selected, so I have to toggle twice to get it to actually load.Finally, it would be lovely if some additional search functions loaded, as I find Subject my most useful tool for finding references. Thanks for making this handy tool! I’d be happy to chip in for its development, if you could see your way to abandoning the subscription model. There are too many of those in our lives these days.

Like the majority of the recent posts and reviews on this app, I am greatly disappointed with the developers decision to go subscription! I have been using calibre library on my laptop, and Calibre companion on my iPad and iPhone for many years having paid for and appreciated it’s simplicity and flexibility. I am simply disenfranchised by this and so many other applications which in recent times, developers have decided to, Basically take advantage of those who have respectively purchased an application in a market please where virtual commodities seem to imply that the consumer has less rights to propriety subsequent to purchase then in a typical brick and mortar commodities industry. It is time that Apple or the App Store take the lead in a market place where regulations are still significantly lagging and either antiquated or inappropriate , in the rapidly changing virtual market place, and develop policies that protect the consumer of their commodities and hold vendors to the usual implied contractual responsibility to their consumers. Consideration could be given to how “possession” is defined and perhaps those who have previously purchased and now “possess” an application on their device can, by way of a grandfather clause, be protected from back end coercion into subscription charges that we’re not part of the original purchase terms and agreement. Sorry Calibre for the rant, but you deserve it!

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.
