As a mobile dev, it's sometimes frustrating finding interesting work and BLE seems to be one area where businesses are willing to do something useful outside of duplicating simple REST calls and occasional multimedia uploads so the app can be at parity with the limitations of a website. Most product people are limited in their thinking of what's even possible because of their narrow usage of the capabilities.

Our phones are packed with sensors, and are more powerful than the computers that landed us on the moon. Apps can be so much more than dumb pipes for simple data upload and download from a server.

Kinda. But there’s still two code bases: one for android (now would be web) and one for iOS.
