Retrieve is a flashcard app that tells you what to study each day. It schedules every card so you see it right before you'd forget it, which is the fastest way to actually remember things. Pay once. 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.

Verdict
The clearest difference is in-app purchases: StudyTodo at none against Retrieve's 1. StudyTodo also leads on iOS requirement (15.1 vs 26.5). Retrieve's advantage is ads (none vs shown) and update cadence (every 2 days vs every 10 days). On price and device support there is nothing between them.
