Introducing the "Milkstrip." A diagnostic test strip similar to those used for blood-glucose testing, but which can plug into your cell phone to be scanned by the company's app. The app can tell a user about the nutritive qualities of her breast-milk, if it has spoiled, and even if any dietary changes are recommended. Also, since pumped and stored/frozen milk degenerates, this test can be very useful. At $1, it's very inexpensive compared to the usual $350 test.
Clever but simple idea! Very cool!
Usually, problems are best solved with simple solutions.
Hopefully people pick up on this one!
