A short session from the topics you already watch. Two taps from the Home tab.
What it is
ration is a curated library of short educational video, wrapped in a timer. The library is browsable at any hour. The session is the part that makes it finish.
The session
A session begins with three choices: how long, on what, from where. ration builds a queue that fits the duration and plays it in order. A Live Activity keeps the remaining time on the Lock Screen, so the clock lives outside the app. At the end there is a short summary and an escape route back to what you were doing.
A short session from the topics you already watch. Two taps from the Home tab.
A longer run on one subject, sequenced so the pieces build on each other.
One session assembled each day by the editor, on a theme.
The app
Free and paid
The free tier lets you browse every category, open any video, and run two guided sessions a day. No video link sits behind a paywall, even after the two sessions are used. Ration Plus, the subscription, adds unlimited sessions, custom session lengths, curated plans, every theme, and a For You feed ranked by your palate.
Curation
Approval happens per kind of video, not per channel. A creator whose documentary work is careful can still make argument videos that do not belong here, and both judgements are recorded separately. Categories with a high density of pseudoscience carry a blocklist. Credentials count, and sourcing rigour can outweigh them.
