Just a suggestion. Keep up the good work!! ### 4/5 — Great game, just one problem *2015-06-22, version 1.5* This game is fun, and it helps me alot with memerizing pi, but when I open my scores, it shows nothing. Am I doing something wrong, or is it the game? Other than that it is fun and i love the set up of the game. ### 4/5 — Simple and fun *2015-01-21, version 1.5* My son and I like playing this game as we learn more digits of pi. I'm up to 230, and he's up to 60. Of course, since he's only three years old, I think he still has me beat. ### 4/5 — Good option for old devices *2014-03-11, version 1.4* Great app! I can't find settings. Also, you should be able to practice starting at a specific digit, and the time completed in and errors should be recorded when you save a score. ### 4/5 — Good *2014-02-22, version 1.4* Would like to be able to start from any digit so I don't have to repeat the beginning every time. ### 4/5 — Pi *2013-03-11, version 1.4* I now know 88 numbers of pi!! Thanks ### 5/5 — Awesome! *2013-01-09, version 1.4* This is a great app! My teacher wanted us to learn at least 20 digits of pi. So that is what I did using this app, except I learned 184 digits. I just said it out loud while typing on the keypad. ### 5/5 — Great *2012-11-19, version 1.4* This is the best pi memorization app on the iPhone yet. ### 5/5 — Amazing *2012-11-15, version 1.4* This app is perfect I love math and pi is one of the basic reasons I love math and it helps me understand this unique number. ### 4/5 — Cool app but… *2012-10-22, version 1.4* I can't figure out how to get to settings!

A keypad keeps popping up when I open the app, so I can't select learn or scores! At least I already know 170..... ### 1/5 — Oops *2010-11-04, version 0* Latest update does not work. ### 1/5 — I can't understand it *2010-05-11, version 0* It's not that I can't learn digets of pi, it's that I can't find out how it works.

Also, my score history got deleted when I updated!! I'm disappointed about that. ### 2/5 — Babysitter *2012-01-25, version 1.4* I thought that I was learning pi but the. When I tried to say it I couldn't because I was used to using the keypad so I'm a bit sad now ### 3/5 — Pi master *2015-11-11, version 1.5* After you past 40 or so, it blocks what row you are on. ## Most praised reviews (10 highest-rated) ### 5/5 — Very good app *2017-07-12, version 1.5* Very good app!
