About

ToneLeaf

Read full description

ToneLeaf drills Mandarin tone recall. How it works: Sessions pull characters from HSK or TOCFL vocab. You see the character, tap the tone (1, 2, 3, 4, or neutral), get instant feedback. Each rep takes a couple of seconds. New characters show pronunciation hints and audio. As your recall gets stronger, the hints fade and you answer from memory. Miss one and the hints come back. Spaced repetition: Reviews are scheduled with FSRS-5 (an advanced spaced repetition algorithm), which surfaces each character around the point you'd otherwise forget it. Less time on the stuff you already know. Vocabulary: HSK 1–6 (simplified or traditional) or TOCFL 1–7 (traditional only). Works with pinyin or zhuyin. Home screen widget — see your due cards and streak, updates automatically as reviews come due ToneLeaf Pro (one-time purchase) - HD native speaker audio for every character - Recall Test: a cold, unscheduled test with no hints — just your memory against every character at once - Weakest Characters drill for the ones that trip you up - Tone Pair Drills for confusable pairs - Manual rating mode and Pro color schemes - Home screen widget — see your due cards and streak, updates automatically as reviews come due Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
