Works great – Kello Review

I don't normally write reviews, but this works like a charm. I simply use the inline mic from the iPhone earbuds and place it on the crystal of the watch. It correctly identified the BPH, which indicated it does work. It shows the accuracy pretty much spot on from basic measurements I take over time against an atomic clock, only this app does it instantly. I can also instantly tell how different positions change the accuracy.
