While the app works flawlessly, they use a counterintuitive scale of 10 on the left and 0 on the right. This has led to some scores submitted erroneously submitted by our customers. After following up with them, they reported that they expected the highest score to be on the right and clicked in haste. We'd use another NPS app if it was available on the App store.

We are getting pretty good results since we installed it. It has help the increase in traffic, definitely recommend this app.
