Supporting Calibre Reader
In effect from 14 November 2026.
In short. Calibre Reader is free to download and use. Supporting it once, for good, lifts the free app's limits and removes its ad. After that, tips are optional thanks that earn badges and gift codes to give away. Both are bought in the app.
What is offered
| Purchase | Price | What it brings |
|---|---|---|
| Supporter — Lifetime | US$8.99, once | Every limit of the free app lifted and the ad removed, for good. |
| Tips | US$1, 2, 3, 5, 10 or 20, as often as you like | Thanks on top of supporting: supporter badges, and gift codes to give. |
The App Store shows each price in your own currency, with any sales tax included where your country requires it. Supporting buys no books or other content: it supports the app's work.
Where to buy
- iPhone and iPad: in the app, under Settings › Support Calibre Reader, through the App Store.
- Mac: the same way, once the Mac app is on the Mac App Store.
- Android, Windows and Linux: coming. When those apps are ready, you will be able to support Calibre Reader from them too. Nothing is sold for them before then.
Supporting is kept with your Calibre Reader account, so it counts wherever you sign in. A Lifetime bought in the App Store also comes back with your Apple Account through Restore Purchases.
What supporting lifts
| Free | Supporting | |
|---|---|---|
| Reading themes | 8 of the app's, 1 of your own | 6 of the app's, 3 of your own, all with pictures |
| Online libraries (servers, clouds, shares) | 2 | Unlimited |
| Libraries on the device | 2 | Unlimited |
| Devices signed in to your account | 2 at a time | 5 at a time |
| Places and notes kept in step across devices | Not included | Included |
| Fonts installed for every app | Not included | Included |
| Ads | One, on Home | None |
Reading itself has no limit, free or not: every book, every format, Read Aloud and your own fonts are for everyone.
Tips
- Tips open once you support Calibre Reader for good, and you must be signed in to your Calibre Reader account.
- Every US$5 tipped in all is a supporter month, and twelve months make a year, shown as badges on your profile. Tips also add up to bookmarks, books, shelves and libraries: a bookmark from US$5, a book from US$25, a shelf from US$125, a library from US$625.
- Every US$7 tipped earns a gift code: Apple's own code for Supporter — Lifetime, to give to someone. Gift codes are mailed to your account and listed on your profile. Each is good for three months.
Refunds
Bought in the App Store. Purchases made through Apple are refunded by Apple, under Apple's rules. Ask at reportaproblem.apple.com, or from your purchase history in the App Store. We can't refund an App Store purchase ourselves, but if something went wrong, write to us and we'll help.
What a refund takes back. A refunded purchase no longer counts:
- A refunded tip takes back the badges and the gift codes it brought, unused codes first. A code already redeemed by someone can't be taken back from them: instead, their Calibre Reader account loses the support it brought.
- When a refund means an account no longer supports Calibre Reader, everything stays as it is for a year, and we tell you by email. After the year, the free limits apply again, and the libraries beyond them close; nothing you made is deleted.
Mistakes and questions. Bought the wrong amount, or bought twice by accident? Write to contact@calibrereader.com with the date and the amount, and we'll help you sort it out.
