This short course teaches you how to use on board hardware – specifically the GPS in this case. The steps taken are similar to accessing other types of hardware so once complete you’ll have a god idea of how to do it for your specific needs using on device hardware.

We also introduce the idea of communicating with web APIs (servers with data on them). I outline the ways you should think about doing this and how certain plugins can get us to the end result faster.

Finally I show you how to implement local notifications so you can send reminders to the end user (without needing to pay for a cloud notification service).

By the end you’ll have a simple app that looks great but actually contains a lot of complexity!

The app will:

• Access your location and ask for permission
• Ask you for your skin type (to determine max UV exposure)
• Retrieve weather data from an online service
• Calculate safe UV exposure time
• Offer to remind the user of overexposure

This is a great way to deep dive into a real app that could be released to the app stores!
