Thanks for the update. – RLM-Fin-PL Review

Update, Sept. 2017: It looks like the developer finally updated his apps, even rebuilding in 64-bit Swift. I haven't fully tested all functions, but I think an upward revision of my review from nearly seven years ago (below) is appropriate. Four stars. ______________________ Old review: DO NOT BUY THIS APP. I purchased this calculator hoping that it would work when the developer's other effort--"12C Classic"--did not. 12C Classic *used* to be decent before the version posted on Dec. 21, 2010, at which point R.L.M. posted an update that basically broke the app for everyone. The developer has been notified multiple times by multiple parties (including me), with no response whatsoever. I purchased 12C-FIN hoping that it would *not* be broken and would solve the issues everyone is having with 12C Classic, but it exhibits exactly the same problems! DO NOT SUPPORT DEVELOPERS THAT IGNORE THEIR CUSTOMERS. R.L.M., you should be ashamed of yourself. You are basically cheating your customers. Apple, you should remove deadbeat developers like this and ban their apps from the App Store forever. It reflects poorly on the user experience. To sum it up: This app and its developer are a great big #FAIL.
