What's New in AlgoApp

15.8.1

November 5, 2026

- Choose whether cards generated from an image show the original image as their background. The option is now available in each deck's Background settings. - Classic review recaps no longer label available cards as due. See today's study activity and progress toward your daily goal, without reminders to keep studying based on an incorrect due-card count. - Fixed rich-text fields shrinking or hiding the writing area when the formatting toolbar wraps. Fields resize correctly after pasting, changing formatting, using Undo, or loading images. - Improved performance during long reviews and repeated card editing, especially with images and audio. - Fixed stalled image and audio uploads blocking later uploads. - Improved automatic recovery from storage errors so the app can reload without long delays or repeated reload attempts. - Updated deck-list progress bars with softer colors, clear outlines, and rounded ends. - Corrected the swipe-mode hint to point in the direction used to flip a card.

New Vibecoded UI is really baf

It was a great simple app that fulfilled its purpose. With latest update the ui/ux is very unintuitive and poorly adapted to mobile (used to be fine!), words are cut off, settings button taking up half of the screen - why?? I have been a loyal user for multiple years, really hope the developers revert and fix it :/

Rip off

I used to use this app frequently and that’s why I bought unlimited but now I have been charged three separate times and I’m not able to get the money back and no one response.
Not only that, but the app is entirely AI content and descriptions of the words are completely wrong

Changed Business

You were able to use it for free but now they’re charging users. Bad for business.

Great but expensive

App is so great in writing reading reviewing editing, works perfectly. But its pro subscription is so much costlier side being an flashcard app (₹2999/year), which is much costly for the students.
If they reduces the charges it will be of great value, it should be around ₹999/year.

Update problems

Since the latest AlgoApp update on my iPhone, I can no longer edit my existing flashcards.

When I open an existing card and select Edit, the editing area is completely blank. Tapping the fields and navigation arrows does nothing.

However, the editor works normally when I create a new card.

My existing cards contain images and text, and I could edit them normally before the update.

Is this a known issue with the new editor, and is there a workaround that preserves my existing cards?
