## What is Flashcards & FSRS?

Remember everything you learn.

Azri (formerly Simple Anki) uses the FSRS algorithm, the most advanced spaced repetition scheduler available, to predict exactly when you will forget each card and schedule your review at the perfect moment. The result is 90%+ long-term retention with less study time.

CARDS THAT MAKE THEMSELVES

Stop building decks by hand. Give Azri your material and it writes the cards for you.

Paste your notes or type a topic — Azri turns it into a deck in seconds.
Snap a photo, drop in a PDF, or record a lecture — Azri pulls out the text, you review and edit it, then it generates the cards.
Pick a card style or create your own, so every deck matches how you study.
Add AI pronunciation audio to the front of your cards, generated automatically when you save.

SMART FLASHCARDS

Azri goes beyond basic flashcards. It tracks the stability, difficulty, and retrievability of every card, then automatically adjusts your schedule based on how you actually perform. No manual intervals. No guessing.

Add images and audio to make concepts easier to remember.
Use a rich card editor with LaTeX for formulas, auto-translate, and multilingual keyboards.
Organize your learning with color-coded decks and folders.
Choose card layouts that fit your study style: front-to-back, back-to-front, or combined.

STUDY YOUR WAY

Study in a way that matches how you learn and what you need to retain.

Spaced repetition with science-backed scheduling that targets long-term memory.
Quiz mode for active recall with instant feedback.
Typing practice to lock in answers by typing them out — with character-by-character feedback that even catches missing accents.
Shuffle or sequential study order for maximum focus or consistency.
Track retention rates, streaks, and your review history to see progress over time.

NOW ON THE WEB

Azri isn't just on your phone anymore. Open any web browser on your computer, scan the code with your iPhone camera to sign in, and pick up exactly where you left off. Review your cards on a bigger screen and build or edit decks with a full keyboard — everything stays in sync across your devices. (Available with Azri Pro.)

### 5/5 — Not opening

*2026-07-19*

Been using this app for 4 years but  not the app is not opening after update, pls take a look

**Developer response:** Hello there! Please contact me by this email: astemirboziy@gmail.com. I’ll try to help you!

### 4/5 — Love it!

*2026-06-16*

Love the app it has helped me study. I just wish the pictures would show up on the quiz portion.

**Developer response:** Hello there! Thanks for your feedback! I'll add images to quiz mode in future releases! 🙏

### 5/5 — Good Free Simple Flashcards

*2026-05-08*

Overall a nice lightweight spaced repetition app with pretty much all the basic features you need. My only suggestion is to have an overall review mode for all cards that allows both front to back and back to front reviews since current I get way more practice going one direction.

**Developer response:** Thanks for the review and for sharing your suggestion. I’m thinking about implementation of reversed cards in future updates.

### 5/5 — Exactly what I need

*2026-04-28*

Thanks for the app! Design is great, functionality is perfect.

**Developer response:** Thanks for your review! The fix is on its way! 👨🏻‍💻

### 3/5 — Allow adding images to cards

*2026-04-09*

The app works fine but I would like to add an image to the cards to learn things image based other than just text like teaching kids animals or colors or maybe learning other things

**Developer response:** Thanks for the feedback! Update the app to the latest version, images are now available

### 4/5 — Little query

*2026-04-08*

One problem I just had! I put a prompt into the ai generator, but the app kept crashing!!

**Developer response:** Thanks for your feedback! Could describe the steps you perform before the app crashes? It will help to identify the issue. You can contact me by email from profile screen.

### 5/5 — Класс!

*2026-04-03*

Отличное приложение, я перепробовала уже кучу подобных, это в топе. Из пожеланий - 1) можно добавить сортировку в колоде карт, например по дате добавления, хочу видеть, какую карточку добавила последней, чтобы случайно не добавить одну и ту же два раза. Или сортировку по алфавиту, чтобы увидеть дубли и удалить их
2) не знаю, насколько это возможно, можно ли добавить клавиатуры по умолчанию для передней и задней стороны? Например я всегда забиваю слова на переднюю сторону на русском, а на заднюю на сербском, а так как у меня много клавиатур, менять туда сюда занимает время. Я видела такую функцию в моноязычных приложениях для изучения слов и переводчиках

**Developer response:** Спасибо большое за ваш отзыв! 🫶 И спасибо за пожелания, в следующем обновлении постараюсь их добавить.

### 5/5 — yay

*2026-03-30*

It’s spaced repetition

**Developer response:** yes! Thank you! 🫶

### 5/5 — An incredible time

*2026-03-24*

Great app!! I love it and it really helped me learn and practice new language skills

### 2/5 — Doesn’t read Anki or .csv files

*2026-03-06*

Constantly says you need to update to the most recent version of Anki but it still won’t import an Anki file. It also says .csv files are blank when they’re not.

**Developer response:** About the Anki, yes it’s a bug, I need to fix the code. But there’s a workaround for now, when you export Anki file there’s a checkmark saying support older versions, then try to import, it should work. About the csv, can you send me the content of the csv file? Seems like it uses an uncommon separator between columns.
