So it's good ### 3/5 — Does what I need but *2015-07-30* There isn't an option to turn off the button clicks. It's very annoying and loud ### 4/5 — Fun *2015-05-13* Nice game, enjoyable, this game doesn't get boring ### 2/5 — Needs more *2015-02-25* Very buggy when closing the menu. Also needs ability to store numbers and/or formulas. Otherwise good. ### 2/5 — Bug? *2014-10-21, version 1.1* The basic functions are excellent, but the instant you slide open the options bar and close it, the calculator is rendered useless. The cursor that was there is now gone, with no way of getting it back. Meaning there is no way to type any numbers in. You have to open the task manager, close the app, then reopen it to get the app just to work again (the basic functions at least;don't slide open the Options bar again or you'll have to repeat this process again). ### 5/5 — Cool bruh *2014-10-02* Magnificent calculator ### 5/5 — Great *2014-09-23* Amazing! Beautiful program. Keep up the good work. ## Frequently asked questions about Calculator83 ### What makes Calculator83 minimalist?
