About this app
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.

Audience growth
Ratings growth
Baseline captured. Growth appears after the crawler observes a changed rating count.
Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
