GPS accuracy not as good as Collector, why?

A coworker is developing an iOS app for collecting inspection data in the field.

 

We purchased a couple EOS Arrow 100's which are supposed to work with the Collector app, so we figured they'd work with our custom iOS app.

 

But, we did some testing, and the Collector app collects much more accurate GPS points than our app. Any idea why this is? Is there any documentation for best practice on using our own external GPS receiver.
