One Line helps you memorize long passages one line at a time. Save scripture, poems, speeches, scripts, quotes, or any passage you want to remember, then practice each line with a focused recall workflow. Paste or type a passage, break it into memorization lines, and work through the passage in small pieces. Practice mode hides parts of each word so you can strengthen recall without losing the shape of the line. Reading and listening modes help you review the full passage before focused practice. One Line is built for people who want steady recall instead of cramming. Your library and progress sync across your account, and Pro unlocks a larger saved-passage library with room for future Pro features.

About

Soranji

Features
Read full description

Soranji is a quietly beautiful flashcard app built around one idea: memory grows through recall, and recall is easier when the app feels good in your hands. WHY SORANJI IS DIFFERENT • Memory curve - see the forgetting curve for each word, how strong the memory is, and when the next review is due. • Word Ledger - browse words you have not touched in a while, weak spots, and “almost there” words that are correct but slow. • A footprint you want to keep - a study heatmap and streak that celebrate showing up without punishing missed days. BUILT FOR REAL MEMORY • Spaced repetition inspired by the Ebbinghaus forgetting curve. • 11 study modes, from matching and multiple choice to spelling, handwriting, and quick reflex games. • Reading and writing are tracked separately, so a word you can read but not spell comes back on the side that needs practice. MAKE PAIRS IN SECONDS • Paste two-column word lists. • Import from files, or extract pairs from text and photos on device. • Start with built-in vocabulary packs, then make them your own. PRIVATE BY DESIGN • No account required. • Your words and learning analytics stay on your device. FREE & PLUS • Free: up to 3 files and 150 pairs. • Soranji Plus: unlimited files and a higher pair limit.

Soranji's advantage is update cadence (every 5 days vs every 5 weeks). On price and in-app purchases there is nothing between them.
