Markdown Cards
Read full descriptionHide full description
Markdown Cards is the fastest way to make a stack of flashcards on iPhone — and the simplest way to study them. You can build a stack in two ways: WRITE IT: Open the markdown sheet and type. The format is deliberately tiny: • # for the stack title • ## for the front of a card • ### for the back of a card GENERATE IT: Tap "Generate with Apple Intelligence", describe what you want to memorize (e.g. "top AI terms", "interview Q&A", "art movements", etc.), and the on-device model writes a full deck in the format above. The result drops straight into the editor — edit it like anything else, or save as-is. That's it. No body text, no lists, no formatting. The editor lints your file in real time and saves when it's valid. DESIGNED FOR STAYING OUT OF THE WAY: • Every stack is a markdown file. Nothing proprietary. Copy, paste and share. No accounts, no exports, no import wizards. • Apple Intelligence runs on-device. Or use your favorite AI tool to generate a markdown. • No subscription, no paid to unlock, no login. • Open a stack. Tap a card to flip. Swipe to advance. Tap and hold to edit a card or stack. WHO IT'S FOR: • Anyone who wants a dedicated and simple flashcard app. • Devs or any technical professionals who would rather write markdown than fight a clunky UI. • Students who don't want overly complicated flashcard app with subscriptions. • Anyone who remembers HyperCard and wonders why apps today stopped being simple and elegant. REQUIREMENTS: • In-app generation of cards requires iOS 26 or later on a device with Apple Intelligence enabled in Settings. The rest of the app works on older iPhones — you just won't see the generate button do its thing. PRIVACY: This app uses GlitchTip to report crashes and errors so bugs can be diagnosed and fixed. No personal data is collected, and nothing is used for tracking or advertising.

Verdict
The clearest difference is in-app purchases: Markdown Cards at none against Solo's 2. Solo's advantage is device support and iOS requirement (13.0 vs 18.6). On price there is nothing between them.
