OurPact and Pinwheel have taken very different approaches to kids and tech. OurPact is an app that you "add on" to an existing adult phone or tablet. Pinwheel is designed from the ground up as a kids phone, combining hardware and software in one product.
Pinwheel designed a healthy, research-backed smartphone for raising free range kids in a digital age.Pinwheel is only available on Pinwheel phones. This is why it works so well.
OurPact is continually playing "whack-a-mole", attempting to work on any device from the 1,000+ Android devices to the Apple ecosystem as well. This is why it doesn't work on any of them that well, has loopholes, and results in a lot of frustration.
