Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Education apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About eReaders Black Cat - Cideb
Cideb and Black Cat graded readers, an international standard for learning foreign languages, are finally available as part of a single app: eReaders provides you with a new way to use books that have long stood out for their creativity, innovation and quality.
With eReaders you can find all the publications you have activated on your profile on the website blackcat-cideb.com, buy individual books or take a monthly subscription to the whole available catalogue.
Cideb and Black graded readers are available for studying English, French, Spanish and German; they are aimed at different levels of ability and age and are suited to independent study, group or class work and for preparing for international certifications (CAMBRIDGE, TRINITY, DELE, DELF, FIT).
Characteristics and contents
· Full audio of the Read Aloud text to follow the reading step by step.
· Activities and exercises to test your progress.
· Data synchronisation with the web version of the app available from the blackcat-cideb site.
· Wonderful illustrations and animations.
· An ever-growing catalogue searchable by language, age and level.
Languages and series available
· English (EarlyReads, Green Apple, Reading & Training)
· French (Facile à lire, Lire et s’entraîner)
· Spanish (Leer y aprender)
· German (Lesen und Üben)
The “Activate” feature allows either the purchase of a single book with a one-time non-recurring payment or access to the entire catalogue by subscribing to a recurring subscription.
There are 2 types of “subscription” available:
· Paying € 9.99 a month gives you an ongoing monthly subscription that is renewed automatically.
· Paying € 59.99 a year gives you an ongoing annual subscription that is renewed automatically.
The cost of the subscription will be debited from your App Store account after the purchase is confirmed.
The renewal can be deactivated at any time in your App Store settings. To prevent the subscription being renewed automatically, it is necessary to cancel the renewal at least 24 hours before payment is due.
If the renewal is active, it will be debited within 24 hours of the previous subscription ending.
It is not possible to cancel a subscription for the period underway once it has been activated or renewed.
The purchased books are always available (even offline) in your library. In your personal library, you can also find all the books you have activated on the website blackcat-cideb.com using the code printed at the end of your book.
Enter the library and look for your books in the “My Books” section; once you have downloaded the book you want to consult, you can always find it in the library under the “Downloaded” section.
