Anyone used Ajusto for car insurance discount recently?

Hi, has anyone been using Ajusto program to track driving habits to get discount on insurance? I did mine in late 2018 and got 14% discount while driving a stick shift. I was wondering what you think about that app. Should I restart my 100 days on automatic car and hope to get a better score? Or is the app too sensitive to braking and acceleration to grant you anything over 15%?

Let me know your thoughts.
