Does ProtoPM work on a phone and offline?

Reviewed October 2026

ProtoPM works in any modern phone, tablet or desktop browser, and can be added to your home screen. There is no app-store app and no offline mode yet: it needs a connection, so enter logs and punch items where you have signal.

It's free to run projects in ProtoPM.

On a phone

  • Open protopm.app in Safari or Chrome, or add it to your home screen.
  • Take site photos with the phone camera when you upload to the Files tab.
  • Daily logs, punch items and the schedule work in the phone browser.
  • The app is available in English, French, Spanish, German and Portuguese.

Without a connection

ProtoPM does not work offline today, and changes made without a connection are not saved for later. Where signal is poor, jot the day's notes on paper or a spreadsheet and enter them when you are back online.

A free daily log template is handy for dead zones.
