Very Inconsistent, Simple Idea Poorly Executed – Kello Review

This app is painful. It seems that if the movement you are trying to time has any level of beat rate error, Kello bombs out and will not work. It will just hang endlessly on "determine frequency" and "gathering signal data". Then after many minutes of hope, ultimately it will give you an "out of range" or "poor signal quality" error. Get the Timegrapher App instead.
