Features & Capabilities

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.
