Here is an app enhanced test kit that helps you stay on your keto diet. The Spark Mobile Diagnostics Ketone-pH Test Strips let you test your urine for the presence of ketones. You can get a result fast by scanning these with your iPhone camera. All you have to do is dip the test pad of the strip in your sample, place the strip on a flat surface, and wait for the timer in the app to let you know when you should take a photo.
The companion app measures ketones in your urine and can also track your macros such as carbs, proteins, and fats. Your data is visualized, so you can make better sense of your progress.
