AlgoApp - Flashcards
authentic ratingAlgoApp (formerly Flashcard Hero) is one of the best pure SRS tools on iOS. It supports FSRS one of the most accurate spaced-repetition algorithms available along with AI card generation and cross-platform sync. The technical issues are real, but longtime users give it high marks for good reason.

About the rating
Store average 4.67 vs text average 2.78 with 30% five-star reviews a noticeable gap. Negative feedback clusters around technical issues (crashes, sync, UI overhaul) and monetization, not the algorithm itself. Long-term users with 5-10 years of experience give high ratings deliberately.
Strengths
What users love
- The FSRS algorithm adapts the review schedule to your actual responses more precisely than Anki's classic SM-2. An AI assistant generates cards right inside the app. There's a huge library of pre-made decks to download.
Weak spots
What users hate
- Sync between devices is unreliable. CSV import doesn't auto-convert phonetic transcriptions. Cards inside downloaded community decks can't be edited.
Who it is for
Serious language learners and exam preppers who want a top-tier repetition algorithm and the ability to build their own material.
