The app is now updated and you should be able to play. ### 1/5 — Scoring is poor *2018-12-29* Not sure what scoring is based on, but it’s not consistent or good. Waste of money. ### 1/5 — Unhappy face *2018-03-25* The scoring feature does not work. After every circle it gives me a frown face. Sort of how I feel about this game. Great idea, poor execution. ### 1/5 — Terrible and inaccurate *2015-03-14, version 2.0* The calculation seems to be based on the number of points measured during the time it takes to draw it. What I mean is, you can draw a good circle really quickly and get a low score, or take your time drawing a bad one and get a better score. It's certainly not based on the actual shape. ### 1/5 — Inconsistent *2014-10-20* Random numbers popping out, would not suggest. ### 1/5 — Wiped my scores! *2014-08-05, version 2.0* Really annoyed that the update wiped my top scores! Not cool! ### 4/5 — Fun *2014-07-30, version 2.0* Surprisingly addictive, but disappointed that the update wiped out my high score without any warning. :( ### 5/5 — Spent hours playing *2012-03-30, version 1.5* Really is very addictive and a lot of fun...great app. ### 5/5 — Incredibly addictive *2012-03-25, version 1.5* Who knew that drawing circles over and over again could be so much fun! ## Frequently asked questions about Perfect Circle ### What is Perfect Circle?
