9月23日的Channel Timeline Viewer应用程序分析

Channel Timeline Viewer lists a channel's uploads by publication date — oldest first — so you can work through an archive, a course, or a long-running series from the very beginning without losing your place. WHO IT'S FOR • Anyone catching up on a channel's back catalog • Learners following a course or lecture series • Viewers who want to know exactly how far they've watched MAIN FEATURES • Paste a channel URL, or share a video or channel from the YouTube app or a browser • Uploads listed oldest-first (or newest-first) • Per-channel progress: watched count, percentage, progress bar • "Up next / Continue" takes you straight back to where you stopped • Resume from the exact second you left off • Optional autoplay to the next video in the list (off by default) • Repeat one or repeat all • Mark videos watched or skipped; play unwatched only • Filters: all / unwatched / watched • Notes for each video, for studying or series viewing • Playback speed and captions controlled outside the player • Position shown as "February 27, 2026 (1,034 / 3,500)" • Five navigation buttons — first, previous, undo, next, last — where undo restores both the video and the position you were at • Channels you have opened before load instantly from a saved list • Available in English, Japanese, Simplified Chinese, Spanish, German, French and Korean PLAYBACK Videos play in YouTube's official embedded player (IFrame Player). FREE AND PRO You can save one channel for free. Inside that channel everything works without limits: sorting, watched tracking, resume, jump buttons, notes, progress, and playback in the official player. You can swap in a different channel for free, but doing so erases the watched history, progress, and notes of the previous one. To follow several channels side by side and keep every record, buy Pro. It is a one-time purchase, not a subscription. PLEASE NOTE • This app is not the official YouTube app. • It does not download videos, block ads, or play in the background. • Video lists are retrieved via the YouTube Data API v3. • Autoplay is off by default and only moves to the next video in the list you opened. • No ads. No subscriptions either — Pro is a one-time purchase. • Watch history, progress, notes and playback positions stay on your device. YouTube is a trademark of Google LLC.
