Supported ebook reading apps
The following guidelines apply to test reading campaigns organised by Jellybooks.
Reading data can only be collected for ebooks that have been provided by Jellybooks directly to you and only with reading apps listed as supported by Jellybooks.
The reading data is collected by Jellybooks using a small piece of software called candy.js. The code is embedded directly into the ebook (provided as ePub3 file) that we make available to you the reader.
Not all reading apps are suitable for use in test reading campaigns organised by Jellybooks.
Please note that the list of apps supported by Jellybooks is much narrower than the list of apps, formats and devices that the book’s publisher supports. The collection of reading data imposes constraints that render some third party apps and devices unsuitable for use in test reading campaigns. If you find this too constraining, then please do NOT participate in test reading campaign organised by Jellybooks.
The listing of an app on this page does not mean that the app’s developer has a commercial relationship, joint venture or similar with Jellybooks and the list below is a technical guide only and does not constitute an endorsement by Jellybooks or any other company of a specific ebook reading app or device.

Adobe Digital Editions (ADE) by Adobe
version 4.0 or higher only (not earlier versions!!)
compatible devices: PCs and laptops (Windows)
Warning: Please make sure you have upgraded to version 4.0 or higher. This app has some known bugs. It is best to sync only at the end of a session and not at the end of each chapter. We strongly encourage users who are participating in Jellybooks test reading campaigns and reading on a PC or laptop to use the Jellybooks Cloud Reader.
Reading on Multiple Devices
You can read the ebooks we provide on multiple devices, but you have to download them manually to each device by going to the “My Books” section Jellybooks. Your reading stream will even show on which device you read (if the screen size changed, the color of your reading stream will change, too, if you look it up in “My Data” on Jellybooks).
Sending Reading Data
When using any of the apps above, the book will collect reading data and store it on your device. Once you press the purple “Sync Reading Stream” button, the entire database of reading data that has been collected and stored on your device for that specific ebook will be uploaded to Jellybooks. Data collected for other books will not be uploaded. Every sync action is unique to the book in which the sync button is clicked. However, this only happens if you are online. If you are offline, click the button the next time when you are online. Skipping a button does not lead to data loss, but clicking often is the best way to make sure all the data is captured. The data will not be deleted from your device after it has been uploaded.
If the data has been successfully sent, the purple “Sync Reading Stream” button will switch to a purple “Thank You” button. Depending on the device, app, and operating system, you might see a web page saying that the data has been successfully sent, but in many cases, it is only the button that will change. If you are using Adobe Digital Editions (ADE), the app may occasionally get stuck on the “data received” page. This is a bug in the ADE application (generally a very buggy reading application), and not a Jellybooks error. If this happens, just close the book and re-open it. A workaround, if this becomes annoying, is to send data only at the end of a reading session when using ADE.
Single-click process (on some devices)
Two-click process (on all other devices)
Support discontinued
Bookvia is still a supported app, but the developer ceased to make this app available through the Google Play store in February 2019; if you are using this app, you should be OK, but there will be no further upgrades to the app in the future
ebook Reader from ebooks.com used to be supported by Jellybooks but following a major app upgrade (versions 4.1 and up) we had to discontinue support (reasons: loading and pagination issues, local storage on Android no longer supported); if you are still using this app, then please switch to an alternative Android reading app that is actually supported by Jellybooks
