Prime Speed Controller is a Safari extension that adds A-B loop repeat, playback speed control, seek, and time-saved tracking exclusively to Prime Video on iPhone and iPad. Perfect for language learners and anyone who wants to get more out of Prime Video. ■ A-B Loop Repeat Tap A to mark a start point, tap B to mark an end point — the video loops that segment continuously. Replay any dialogue, scene, or lecture as many times as you need. ■ Playback Speed 15 presets from 0.5x to 5x, with 0.05x fine-tuning. Subtle steps like 1.1x and 1.2x let you boost speed while keeping audio clear. ■ Forward & Rewind Choose 5, 10, 15, or 30-second intervals. Jump back instantly to catch missed dialogue. ■ Time-Saved Tracker The panel shows how much real time you have saved by watching above 1.0x speed, accumulated across sessions.
