Welcome to the SBLE-iOS data collection study!

We are looking for volunteers to participate in a data collection study

If you are a UCSC student, own an iPhone, and take the UCSC campus shuttles regularly, you are invited to participate in the study. All you need to do is:

• Fill out an online form, where you will also sign a Consent Form.
• Install TestFlight, an app made by Apple that allows you to run test apps on your iPhone.
• Use TestFlight to install our SBLE-iOS app, and create an account.

That's it! Your iPhone will remind you to start the app when you ride the campus shuttle, and will send you a few notifications, asking you whether you are in the bus, which part of the bus you are sitting/standing, and if you left the bus.

If you accept to participate, you will receive a $30 gift card after you install the SBLE-iOS app.

In addition, between May and September of 2023, we will give out a $150 gift card each month to a top app user.
