Addit

Fig. 1 Addit’s launch screen, running in this page. The boxes are a tracker reading the dots you’re looking at — none of it is keyframed. ClickTap the water.

Your folders are already albums.

What it is

Addit is a music player for Google Drive, OneDrive, and local storage. Point it at a folder and it plays like a record — artwork, track order, gapless, offline.

Here it is, running.

In the order it was meant to be heard.

  1. 1

    The order lives in the folder. Everyone you share it with hears the same album.

  2. 2

    So does the artwork, as cover.jpg.

  3. 3

    Nothing is copied. The folder is the library.

Three more things.

Both clouds, or neither

Google Drive and OneDrive side by side, or just what’s on the phone.

Send it, talk about it

A link opens straight into the album. Each album has its own chat.

One order for everyone

Reorder an album and the change is written into the folder, for everyone it’s shared with.

The player, as an object.

Drag it round; the keys work.
