Fielder is a web/cloud-based system, much like QuickBooks Online or Google Docs. All you need to use Fielder is a computer with a standard web browser and a decent internet connection. Fielder also provides a mobile app for iOS and Android devices. The mobile app is currently designed to support field-technicians, to help them get the information they need about their Jobs. The mobile app is available on the public Apple app store (for iOS) and the Google Play store (for Android). Users can install the app on their own devices.
