ShadowLib: Shadowing Tool

ShadowLib turns audio and video you already have into a focused shadowing workout. Import a clip, attach its subtitle file, and the app splits it into sentences you can loop, slow down, and repeat until the rhythm sticks. IMPORT YOUR OWN MATERIAL • Add audio and video from Files or your photo library (MP3, M4A, WAV, MP4, MOV, WebM) • Attach an SRT or VTT subtitle file to practice sentence by sentence • Add a second subtitle file to show translations alongside the original • No subtitle file? Play and record over the whole clip as it is PRACTICE SENTENCE BY SENTENCE • Jump to any line from the sentence list, or search for the one you want • Set a loop count and let a sentence repeat while you shadow it • Slow playback down until you can keep up, then bring it back to speed • Blind mode hides the text so you train your ear instead of reading • Show or hide the translation whenever you need it RECORD AND COMPARE • Tap once to record yourself shadowing • Play your take back against the original • Re-record as many times as you like KEEP YOUR LIBRARY IN ORDER • Organize materials into folders • Filter by audio, video, or recently played • Search material titles • See how many times you have practiced each material • Pick up where you left off with Continue last practice BUILT TO STAY OUT OF THE WAY • Light and dark themes • English and Chinese interface • Set your default playback speed and loop count once Your practice recordings stay on your device.
