Matinee

A watch-later queue, curated by you instead of the algorithm — YouTube channels, Raindrop bookmarks, and any link you share, in sync across iPhone, iPad, and Apple TV.

Matinee is an iOS and tvOS app that holds the videos you said you'd watch later — channels you follow on YouTube, bookmarks you save in Raindrop, and anything you send through the share sheet. The queue stays in sync across your devices through your own iCloud, and more sources are on the way. Built in SwiftUI with SwiftData and CloudKit, it ships without servers of its own or third-party tracking.

Things I learned

  • Competitive cyclists shave their legs for aerodynamic reasons, which was discovered by engineer Marc Cote after he built a wind tunnel specifically for cyclists. Research showed that shaving could save 70 seconds over a 40-mile time trial.

  • It takes 55 times more energy to go to the Sun direction than it does to go to Mars.

  • Electrons in a copper wire do not travel at the speed of electricity. Not even close.
  • If you shuffle a deck of cards, it’s most probable that order of cards has never been shuffled in the whole of human history

  • Neutrinos, subatomic particles created in the sun, are so neutral and small and that a wall of lead a light-year thick has 50/50 chance of stopping one. About 100 trillion of them pass through your body every second
