Walkman Hotline — two screens of the app, a cassette on each, on blue

Two listeners, one tape.

In 1979 the first Walkman, the TPS-L2, came with two headphone jacks and a hotline button that opened a microphone, letting you talk to the other listener over the music. The app revives that: two people share one tape, and a Hotline key lowers the music for both while you talk. What you say stays on the tape at the point where you said it.

A tape has a length.

Sides shows each side’s fill against a C60 or C90, says too long when it overflows, and lets songs move across. Together lists both listeners and every hotline note, with its side, time and the song it was said over.

The tab bar is the TPS-L2’s keys.

The current screen’s key stays down. Besley and Archivo, in Walkman blue and silver. On desktop the app stands on a stage, with the J-card at poster scale following the colour and track list chosen in the app.
