It very clearly states that the latest update is not for the older, small screen phones. I guess some people just can’t read. ### 1/5 — Turned a good app to crap *2014-09-20, version 4.0* This app was nice, got a iphone 4 and updated all apps. Now it does not work, went back and the notes do say do not update if you have a 4 or 4s. I always use update all apps and never had a problem. If you don't put in support for a phone you should block the update. You broke an awsome app. I want iphone 4 support back or my money back. ### 5/5 — Very helpful program! *2013-12-17, version 3.0* Bring back the old colors of the interface. Cork on steel for a machinist not so good. Give us some color options. ### 4/5 — Nice App *2013-10-26, version 2.2* Really would like to have a mic over ball calculator on it. And prolly a few other things but it's a nice app for the reference it has. ### 2/5 — Machinist job shop pro *2013-03-24, version 2.1.1* Does not calculate angles correctly. If you enter angle and one leg does not calculate other leg correct ## Frequently asked questions about Job Shop Machinist Pro ### What kind of calculations does Job Shop Machinist Pro offer?
