SpeedPlayer helps you practice with your own audio or video using variable speed, A–B loops and per-file playback memory. Precision review uses 0.01x–0.24x; continuous playback uses 0.25x–4.00x. Optional Pro adds history, favorites and visual options.
When to use it
Repeat a short instrument phrase, a language passage or a movement sequence without repeatedly finding the same position.
Limits to check
Extremely slow review and continuous playback are separate modes. A URL import needs a network connection. Pro has monthly, yearly and lifetime options; it is not a blanket subscription-free product.
Storage and connections
Local media workflows run on-device. Fetching a direct URL contacts that media source; sharing or importing from other apps follows their own data settings.
A practical workflow
-
Import media from Photos or Files, another app or a direct media URL.
-
Choose the speed mode and set an A–B loop around the passage to practice.
-
Return to the file's remembered position and check subtitle or audio-track choices where available.
