Easier imports, editable NRL timing offsets and a refreshed look

4 May 2026 · Build 9.93

Piston 9.93 makes importing easier and fixes a number of drawing and session problems.

📂 Sessions and importing

Import button. Added to the Sessions List so you can pick and import Piston Composer and Piston Session files more easily.
Mac package support. On macOS, PComposer and APiston files can now be viewed as Mac packages.
Better UUID handling. Improved for imported sessions.

NRL Data API. The default offset timing has been adjusted, and you can now edit timestamp offsets manually.

The Piston logo is updated on the splash screen and in processing menus such as concatenation and Composer exports.
The Edit Drawings menu, opened by a long press, has been redesigned.
Localising, HLS and MP4 controls are back at the top of the Start Session menu.

Removed unnecessary warnings and connectivity checks when opening server sessions. These could block access if the session list had not refreshed or if you were using a manual IP address.

Partial sessions could not be finalised if the device was disconnected from the server or the server session had been deleted.
Downloading a partial session wrongly started localisation and removed the video instead of moving on to concatenation.
Angle calculation drawings could appear outside the video on panoramic footage and could not be moved.
Drawing anchor points outside the video could not be adjusted.
Fixed a crash when swiping to delete a marker in the sidebar.
