No subscription, no ads, no account. HOW IT WORKS Make a deck and add cards. Each day, Retrieve shows you the cards that are due. Flip a card, tap how well you knew it (Again, Hard, Good or Easy), and Retrieve picks the next date for it. There's nothing to set up. GET YOUR CARDS IN • Type cards one at a time, including fill-in-the-blank cards • Paste a list of terms and definitions. Retrieve works out the format. • Import a CSV or TSV spreadsheet • Import .apkg deck files, with their images and tags • Turn a photo of a diagram, map or textbook page into cards that each hide one label STUDY WITHOUT GETTING BURIED • New cards are capped at 20 per deck per day (you can change it), so a big deck doesn't flood you • Each deck shows how many cards are due today • The grade buttons show when you'll see the card again • Cards you miss come back later in the same session • Optional daily reminder at a time you pick • Study by tag, or review ahead when you want extra practice FIND AND TRACK • Search every card in every deck from the main screen • See your day streak, total reviews and cards learned YOUR CARDS STAY WITH YOU No account, no sign-in, no analytics.
