WillowTree Apps Named Microchip Design Partner

Microchip Technology recently announced its first App Developer Specialist—WillowTree Apps—the latest company to join its Design Partner Network. WillowTree is an iOS, Android, and Mobile Web app developer that enables Microchip’s customers to focus on Internet of Things (IoT) designs.MicrochipWillowTree

WillowTree wrote the first mobile app for Microchip’s Wi-Fi Client Module Development Kit 1, which is available in the Apple App Store. It enables customers to quickly get up and running with the kit’s cloud-based demo. WillowTree can also modify this cloud-demo app to suit a broad range of customer IoT design requirements.
