A Focused, Powerful Player
- Clean and elegant: stay focused on the sentence and the sound.
- Smart & Powerful: segment editing, difficulty management, automated practice flows, dictation, shadow reading, speed control, and adjustable gaps — all within reach.
Dictate on a Computer with a Keyboard, Faster
- Dictate with full focus using keyboard shortcuts — the text saves straight back to your phone.
- Same Wi-Fi network or phone hotspot, either way you can always connect.
- Paired with Auto-Navigate, it feels like a real exam.
- Paired with review mode and difficulty tags, drill your trouble spots again and again.
Auto-Segmentation, Many Ways to Get There
- Smart voice-activity detection draws sentence boundaries automatically — set a preferred segment length or fully customize it yourself.
- Already have an LRC / SRT subtitle file? Generate segments straight from it, with the original text imported along.
- Want to use segments a friend shared with you? No problem.
Mark Trouble Spots, Practice with Focus
- Spend your time on what still trips you up — tackle those sentences first.
- Rate each sentence for difficulty and mastery, then filter by difficulty to practice with focus.
Shadow It, See How Close You Sound
- Listen to a line, read it back, and get an instant score for pronunciation and rhythm.
- Put on headphones and the original plays back in sync while you record — echo it in real time.
Auto-Navigate, More Reps on Trouble Spots
- Trouble spots get extra rounds automatically — just listen and write.
- Speed, gaps, repeat count, and difficulty-based extra reps are all yours to customize.
Trim Segments Down to the Millisecond
- Drag the slider for a quick, rough trim of where a segment starts and ends.
- Use the dial for millisecond-precise positioning.
- Merging, splitting, and trimming excess silence at the edges — all quick and intuitive.
See How Your Practice Is Going
- See your mastery status and difficulty breakdown at a glance.
- The hardest, most-practiced, still-unmastered sentences rise to the top — one tap to practice them.
