Funky town is quite complicated song and please remember the main purpose of this app is to do simple calculations. It's not digital piano. ### 4/5 — Classicalc *2017-04-12* Makes cipherin' more fun. Took awhile to figure out how to clear. ### 4/5 — Number location *2017-04-01* Thanks for changing the number positions to resemble a calculator. I am surprised though that it took a year to make the change. **Developer response:** Yes, you are right I should change that faster (we were working on another cool apps: https://itunes.apple.com/developer/marek-ekes/id789876136). Many thanks for updating the review! ### 2/5 — Eh *2017-03-31* Kinda bad because the piano doesn't have any collaboration with other keys like if you press one then another it will stop the first, lag and then play it the note. Not clear feature **Developer response:** I have corrected this issue in update to version 2.1 which was published yesterday. Thank you very much for your feedback. I kindly ask you to update your review if Classicalc is better now :) ### 5/5 — A hidden gem! *2017-03-30* This is a joy of a gem. Grab 'em because there's no computing for how much fun you can have playing with it when you're done. **Developer response:** Thank you very much for this great review :) Yesterday I have published an update with important fix so I hope Classicalc is even better now. I kindly ask you to repost your review if you like the app :) Have a nice day :) ### 1/5 — 1 + 1 x 2 = 3 ??? *2016-02-06* Totally useless application. 1 + 1 x 2 = 3 4 + 2 x 2 = 8 2 + 7 x 2 = 16 Etc. **Developer response:** Classicalc calculates expressions using mathematical order of operators (x / + -). If you would like to add 1 to 1 and then multiply the result by 2, you should write (1+1) x 2 ### 5/5 — Best *2015-08-04* The only calculator worth using. Replacement for the Apple standard. Download now. ### 5/5 — DELIGHTFUL! *2015-05-10* So much fun! Two AW screens provide basic arithmetic plus percentages, parentheses for formulas and a back button to delete. Piano note sounds vary from grand to toy but that is part of the fun. Change colors on iPhone app to change on AW. VERY MUCH WORTH 99 cents.
