AlgoApp

AlgoApp provides a spaced‑repetition flashcard system for learning languages and other subjects across iOS, iPadOS, macOS, Android, and web browsers. Users can download from a library of more than 80 million pre‑made decks, import CSV files, or create cards manually with text, images, and,sound via the web client. The app records study sessions that last a minute or less and presents a progress view after each session.

The core of the experience is an advanced spaced‑repetition algorithm that adjusts card scheduling based on the user’s demonstrated knowledge, aiming to focus study time on items that need the most reinforcement. Built‑in decks and support for importing from AnkiWeb allow immediate use, while custom layouts using HTML and CSS enable more complex card designs.

All data is stored in the cloud, providing automatic backup and synchronization across devices, and granting free access to a web client that runs in modern browsers. The macOS version is listed as stable, indicating a mature, production‑ready release.
