I was very excited to use this app as it looked useful, I saw the 3 day trial and didn’t go any further, after the 3 days u automatically get charged and have to pay furthermore to use it, not good

Review on Retain

Best app for studying! I’m in college and this has helped me so much. Especially since I have dyslexia and gives me the one on one time that I need to fully understand what is going on. Definitely get it if you want straight A’s.

Bof

On est obligé de payer pour avoir accès à l’application pff

Ne recommande pas

Franchement, très déçue. L’application est présentée comme gratuite, mais une fois le compte créé, impossible de l’utiliser normalement sans être obligée de prendre un abonnement payant.

Si l’application est en réalité quasiment inutilisable sans payer, il faudrait être beaucoup plus clair dès le départ. Faire croire qu’elle est gratuite pour ensuite imposer un abonnement au moment de l’inscription, c’est franchement trompeur.

Dommage, parce que l’idée de faire des flashcards et des cartes de révision est vraiment intéressante. Mais je ne vais certainement pas payer un abonnement juste pour pouvoir utiliser une application annoncée comme gratuite.

Retain

Ich habe eben versucht mich über die Website als auch App anzumelden und habe mich auch informiert, ob es sicher eine kostenfreie Version gibt, da mir das wichtig ist. Mir wurde versichert, es gäbe eine kostenfreie Version, jedoch habe ich mich angemeldet und mir wurde direkt eine vierzehntägige Testversion von Retain Ultra angeboten jedoch konnte man diese nicht überspringen. Ich habe es dann akzeptiert und dachte mir, ich könne ja nach 14 Tagen einfach kündigen jedoch wollten sie dann direkt meine Kontodaten um dann wahrscheinlich für die Version Geld abzubuchen. Jedoch will ich ja nur die kostenlose Version und man kommt an keinem Weg dran vorbei. Ich würde die App gerne selber testen, weil ich von vielen gehört hab, dass sie sehr gut sein soll. Jedoch ist dies wirklich ziemlich ungünstig, wenn man nicht um diese Versionen herum kommt….

FAQ

What does Retain Cards do?

Retain Cards is an AI-powered flashcard application designed to help users study more efficiently. It converts personal learning materials, such as PDFs, images, videos, and handwritten notes, into automatically generated flashcards. The app then creates personalized study plans based on user-defined exam dates and goals, utilizing learning science principles like spaced repetition and active recall.

How does the AI generate flashcards?

The AI analyzes your uploaded study materials, which can include PDFs, slides, handwritten notes, YouTube videos, and online lectures. It then extracts key information and concepts to create flashcards, which you can verify. This process aims to quickly transform your existing study content into a format optimized for memorization and recall.

Is Retain Cards free to use?

The application is free to download and use, offering core functionalities for creating and studying with flashcards. However, it operates on a freemium model, meaning there are in-app purchases available for advanced features or expanded capabilities. Specific pricing details for these in-app purchases can be found within the app itself.

What are the benefits of using spaced repetition and active recall?

Spaced repetition and active recall are proven learning techniques that Retain Cards incorporates to enhance memory retention. Spaced repetition involves reviewing material at increasing intervals, while active recall prompts you to retrieve information from memory without looking at the answer. Together, these methods help solidify knowledge for long-term retention and improve performance on exams.

Can I use my existing Anki decks with Retain Cards?

Yes, the app allows you to import Anki decks directly. This feature enables users to transition their existing study materials from Anki to Retain Cards, potentially benefiting from the AI generation and personalized study planning features. Your learning progress can also be synced across devices.
