SpeedPlayer: Play Slow & Fast
Video & Audio, A-B Loop Motion
Free · In-App Purchases
Import your own video or audio, slow playback down to 0.01x, set A-B loops, mirror the frame, and resume exactly where you left off.
SpeedPlayer is a local-first practice player built for review, repetition, and focused learning.
It is not trying to be a giant media hub or a video editor. It is built to do one thing well: load your own media, slow it down, loop the exact part you need, remember your context, and help you continue practicing later.
Great for:
① dance practice
② sports movement review
③ instrument phrase repetition
④ shadowing, dictation, and speaking practice
⑤ anyone who needs to replay one moment again and again
Core features:
① Import video or audio from Photos, Files, other apps, or a direct media URL
② 0.01x-0.24x precision review mode and 0.25x-4.00x continuous playback mode
③ A-B loop for focused repetition
④ Mirror, zoom, drag, landscape, and fullscreen controls
⑤ Per-file memory for playback position, speed, A-B range, mirror, and viewport
⑥ Favorites, history, subtitle / lyric import, and audio track switching
Optional SpeedPlayer Pro unlocks:
① full playback history
② unlimited favorites
③ extra themes and app icons
④ monthly, yearly, and lifetime options
If you want a practice-first player instead of another general-purpose media app, SpeedPlayer is built for that workflow.
