Your phone is almost full, and it's mostly videos. Deleting feels wrong, but keeping everything isn't working either. Compression is a better answer β€” the moments stay, the storage comes back. Now you can batch-compress multiple videos in one flow, so you don’t have to repeat the same steps again and again. You can also still send a video directly from Photos, Files, or another app through the Share menu and continue when you return. Choose a compression option to get started quickly, or set your own target file size for a single video. Not sure about the result? Preview an 8-second sample before committing, then decide whether to continue. Once compressed, preview the result and save it to your Photo Library or Files. If the original was from your Photo Library and the new version is saved, you can delete the original right from the results screen. Everything is processed on your device β€” no server uploads, no account required.

Read full description

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. β–  A-B Loop Repeat Tap A to mark a start point, tap B to mark an end point β€” the video loops that segment continuously. Replay any dialogue, scene, or lecture as many times as you need. β–  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. β–  Forward & Rewind Choose 5, 10, 15, or 30-second intervals. Jump back instantly to catch missed dialogue. β–  Time-Saved Tracker The panel shows how much real time you have saved by watching above 1.0x speed, accumulated across sessions.
