Though its designed very well and has great playability, the dartbot cheats. It registers scores that cant be hit with three darts all the time. One time it started a match with triple 20, triple 19, double 18 and single 17!!!! It only takes getting screwed by this thing a couple of matches to decide to write a poor review on the app store. I even tried writing an email to the developer (felt like a complete dart nerd) but still no update with the coding fixed. Unfortunately my only advice is to save your money on this app until you see some updates. $4.99 is not peanuts these days.
