Study Stacks is a flash card study app that lets you take your flash cards everywhere you go, study anytime. • Your cards are grouped into "Stacks". The "Stacks" are grouped into "Subjects". • You can give each "Stack" and "Subject" an emoji to make them easier to pick out. "Stacks" can also get a 'Thumbs Up', or 'Thumbs Down' rating. • When it is time to start studying, 'review' a single "Stack", or a "Subject", or all "Stacks" or "Subjects".  • When you review you can swipe forward to see the back of a Card, forward again to move to the next Card, or back to see the front of the Card.  • When reviewing the front of a Card you can swipe back to see the previous Card.  • While reviewing, onscreen buttons give you the option to click to move back and forth between Cards. • "Stack Collections" let you quickly find all of the thumbs up or down stacks, and recently reviewed "Stacks" too. ## Key features - Organize cards into subjects and stacks - Assign emojis and ratings to stacks - Review single stacks, subjects, or all content - Swipe gestures for card navigation - On-screen buttons for card review - Stack collections for easy retrieval ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/study-stacks/id1527242411/reviews.md ### 5/5 — Brilliantly simple flash card maker *2024-10-26* This little app is excellent and - a miracle - it’s actually completely free and doesn’t try to harvest all your data. It just makes flash cards. You make the subject and name the stacks, then go through and add the front and back of each card. Simple. It will shuffle the cards if you want, and you just swipe through as if it was an actual stack of cards. Really intuitive. An absolute joy to use. I’d happily pay £1 for this and I wish app developers would start doing this again more instead of the whole “free trial” before you have to pay through the nose for yet another subscription. This app is the reason you do your research before buying apps. Never dismiss small apps before you’ve checked them out. Congratulations and thanks to the developer. You star 👏 ## Frequently asked questions about Study Stacks ### How does Study Stacks organize flashcards? Study Stacks organizes flashcards into "Stacks," which are then grouped into "Subjects."
