debriefed

Debriefed is a variable-speed video scrubber for iPhone. Drag one finger across any clip from your Photos library — horizontal movement seeks through time, your vertical position on the screen sets the speed. High up is fine, frame-accurate control; low down rips across the whole clip.

It's a single-purpose tool for people who pore over footage: skydiving coaches, sports technique review, musicians, film students. Nothing connects to the internet, nothing gets tracked, nothing leaves your phone.
