For every good fitness app that does what it promises (-> signal) there are at least 50 bad fitness apps that promise too much and let you pre-pay for the (broken) features you wanted, money you'll never get back (-> noise).

The amount of noise in Fitness apps is so high, nobody really dares to try out small apps. Therefore cool implementations from small devs like the workout-correction might stay unnoticed for years.

Right, and SNR is signal dividied by noise.
