PWA ß 4 CSCW 2019

Earlier this year, the SIGCHI Ops team decided to sunset our native apps for conference programs. As an alternative, we put our efforts into making a progressive web application (PWA) which will allow for faster development time, greater accessibility, and easier maintenance. Being a Papers Co-chair for CSCW2019, I convinced the rest of the organizing committee to let me run the beta test live at the conference.

A few things to note, we still had some people using the older buggy native apps (which aren’t fully turned off yet). The numbers are session based; for example, I had 3 sessions: my mac laptop, my iphone, and my ipad

  • We had 1375 sessions on the main day with no logged errors or server issues
  • In total we had 3850 unique sessions of apps (overlaps between different platforms)
  • 308 unique people logged in and saved user data (about 43% of the conference).
  • 10 and 11 November (the first two days of the main program) were most popular days.
  • 58% of the traffic used the desktop web version (our previous mobile apps were of course limited to iOS and Android devices, so this is quite nice to see a lot of traffic on laptops).
  • Few people added the app to their mobile home screen.
  • Most popular browsers are Chrome and Safari.
  • Most popular platform was Mac OS.
  • Most popular things are events: Receptions, Town Hall, D+I Lunch.
A graph of usage by a day with the main program days exceeding 1000 sessions; other days average 400.

So we’re quite happy with the beta test and are rolling out the PWA more broadly across all our 24 SIGCHI sponsored conferences. We did collect a few bugs and suggestions, but if you have more let us know!

PS: Moving forward, these posts on clicks and browsers won’t be a regular occurence but we wanted to share some data from the beta run and thank everyone for their feedback. Got a question, just contact us!
