Director of Goldrush Computing Inc (www.goldrushcomputing.com). Keep making with Swift, Kotlin, Java, C, Obj-C, C#, Python, JS, and Assembly.
I have made several VUI (Voice User Interface) apps for Google Home and Amazon Echo in the last couple of months.
In the last three sessions, we have made a very accurate location tracking app. In this blog post I use this app and examine the battery consumption.
