Think of the DG-1000 as a tablet or smartphone. Just like a tablet or smartphone, apps can be added. Each app will do something different. When the DG-1000 is released, it’ll have the Gauge app and an Updates app. Other apps will be added in future software updates such as an automated testing app, a tubing assist app, a tutorial app and much more! As we develop and release apps, we will release software updates. When you install the updated software, these new apps will be automatically added. (The DG-1000 will not run apps by third party developers at this time.)
