[ Features ]
■ Learn by writing code
Type code directly into your cards and instantly check the console output.
Supports JavaScript, TypeScript, Python, SQL, and C++ — learn by doing, not just reading.
(JavaScript, TypeScript, and SQL run offline / Python and C++ require an internet connection)
* SQL and C++ code execution is a Pro feature.
■ Create cards with 3 types of blocks
Combine text, code, and image blocks freely to build your perfect card.
Each card has a front, back, and memo section — all supporting all 3 block types.
You can also attach diagrams or screenshots using image blocks.
■ Study with clean, readable Markdown
Text blocks support Markdown formatting.
Use headings, lists, bold text, and more for well-structured, easy-to-read content.
■ Efficient spaced repetition learning
Powered by the FSRS algorithm.
Automatically adjusts review timing based on your understanding for effortless, lasting memorization.
■ Organize and study with tags
Tag your cards to keep them organized.
Create your own categories like "Basics", "Advanced", or "Review" for targeted studying.
■ Track progress with study history and statistics graphs
View your study activity with a contribution graph.
Check overall progress, deck mastery, and rating breakdown — all in graphs.
■ Works offline
Most features — creating decks and cards, studying, and running JS/TypeScript code — work offline.
Your learning data is stored on your device (and in your own iCloud when sync is on) and is not sent to external servers.
No account registration required.
* The following features require an internet connection:
• iCloud sync
• Running Python code (to load the execution environment)
• Running C++ code (your code is sent to an external execution service, Wandbox, to fetch the result. No account or personal information is included.)
[ Other Features ]
• Card search, card duplication, and card transfer between decks
• Shuffle cards to study
• Archive decks and cards (excluded from study and stats; study history is kept)
• JSON export / import (full backup)
• TSV export / import (partial data including card text)
• Daily reminder notifications
• Dark mode
• Partial Bluetooth keyboard shortcut support
• Available on both iPhone and iPad

This update focuses on tag features and on more reliable drag-to-reorder and overall screen behavior.
[ New & Improved ]
• Enhanced the tag's card list: added an "All / Active" filter and a selection mode, so you can remove a tag from or archive multiple cards at once
• The tag management screen now shows the total number of tags
• Tag colors now include "Follow theme" and "Black/White" (auto light/dark)
• Added the primary color (blue) to the deck/tag color pickers as the default for new items, and tidied the swatch layout
• C++ code execution: automatically retries on congestion or temporary errors, with clearer status
• Faster start of study from the card list on decks with a very large number of cards
• Enhanced card search: AND search with space-separated keywords; added a result count, card stats (Pro), and ⓘ help explaining how it works
• Card search: results unified to the same card style as the Home/Card lists; remembers your last search (keywords and deck/tag filters) and adds a clear (×) button
• Improved preview on the card list and search: when the first text is a single line, the second block's content (text / [language] / [image]) is shown on the second line
• Unified the deck/tag create/edit screens to full-screen for more stable behavior while typing (close with the × at the top left)
[ Bug fixes ]
• Fixed an issue where a card could turn invisible when dragged far upward during long-press reordering
• Fixed an issue where dragging downward did not scroll on the tag management and card list screens
• Fixed an issue where the on-screen keyboard's visibility state could remain stuck after closing an input screen, causing other screens to scroll incorrectly
• Fixed an issue where consecutive long-press reordering could cause an error on decks with a very large number of cards
• Fixed an issue where the Home deck list didn't auto-scroll at the screen edge during long-press reordering
• Fixed an issue where the second line could be hidden in the card list at the "Small" font size
Plus minor text/label adjustments and other small improvements.
