Lectures, word for word.

Record the class, film the board, and find any moment later with a word.

Just listen

The words appear as they're said, right on your iPhone. Lock it and it keeps recording.

Every board, before it's erased

Film the board or the slides: Trunk keeps them as stills, chosen on the phone, read and pinned to their moment.

Astronomy 101: the outer planets, a recorded lecture, its slides and whiteboard kept at their moments along the recording

Find it the night before the exam

Search a word, even one only written on the board, and play the lecture from right there.

A search for “Kepler” finds Astronomy 101: the outer planets, showing where the word was found: “…It rolls around the Sun Kepler's third law T² ∝ a³…”

Send it to whoever missed class

One link with the voice, the boards and the words. It opens in a browser, no app needed.

Questions

Slides on a projector?

Film the screen while you record. A still of each slide is kept when it changes, if it stays up for about 4 seconds, chosen on the phone.

Can I lock my phone?

Yes, and the sound keeps recording. Filming needs Trunk open: if the phone locks, the film stops and the sound goes on.

Will it fill my phone?

Filmed video stays on your iPhone, about 0.7 GB an hour in Memory Quality. The cloud library keeps the stills of the boards and slides, not the video.

How much for a term?

Free writes down two hours a month, about two lectures. Trunk Pro makes transcription unlimited: $4.99 a month or $29.99 a year.

Can I take a link back?

Yes. That stops new opens, not copies already saved. A link lasts 30 days, or 7 or 90 if you choose (30 at most if you're under 18), and making one needs sign-in.

Pro adds unlimited transcription. Privacy is never for sale. See pricing →
