If so, I could not find how to select it. ### 3/5 — Update: problem needing resolution *2017-12-17* This was my favorite minimalist app until just now when the premium version I had installed reverted to the basic version. This happened immediately after I tried the new OS11 dark theme. DON’T DO IT YET! Then reverted back. Developer, I can’t get ahold of you but could tell you how to replicate the condition. Please fix. Will revert to 5 stars when fixed. Three for now because this is in total a major function and aesthetic loss that I can’t undo. Part Apple’s responsibility; part developer’s. Also, can’t find you on Google App Store. Are you there? Ready to be resatisfied. ### 5/5 — Wonderful App *2017-09-07, version 5.4.2* lots of functions. perfect for university students like me. love the programming calculator!!!!!!!!! ### 4/5 — Money-quality *2017-05-13, version 5.4.2* Though it cost money for the Graphing section, it has a well put feature for you to test it out before actually buying it same for the Programming configuration. If I remember correctly I think the app costed money, but I dont remember, but I think it's worth buying and all( the best calculator I've ever ran into) it's quite useful when or not my own non-phone graphing calculator dies and it's just fun and super easy to use this app. Also to get the other features besides the standard scientific-Calculator is $1 I'm pretty sure that's a good deal. Worth it every way, but every app needs improvement and anyone can help the developer do that. 🔗 ### 5/5 — Awesome! *2016-12-10, version 5.4.2* Perfect! 10/10 ### 5/5 — Fantastic Calculator *2016-05-17, version 5.4.2* I have been using this app for 2 years.

I has everything that I need or want for a calculator. ### 5/5 — I personally use it way more then the school calculator *2016-02-18, version 5.3* I think it's super handy and fast I use it for graphing in physics and it never fails me it can do all that the school calculator can do ( graphing wise ) ### 5/5 — Apple Watch *2016-01-07, version 5.3* I love this app for the watch non laggy, accurate, responsive, the only change id probably like is to add a backspace for example replace the All Clear button with a backspace incase of a mistake and use the force touch feature to clear all instead of having a button for it. ### 5/5 — Apple Watch *2016-01-03, version 5.3* Super fast, immediately and accurately responsive. Just a simple calculator that can easily hit all buttons from one page (on 38mm watch). Can see what you entered, and totals without hitting "=." ### 5/5 — Best free scientific calculator without ads! *2015-12-18, version 5.3* Best free scientific calculator without ads! ### 5/5 — Amazing *2015-11-29, version 5.3* So helpful especially the widget ❤️👍🏽👍🏽 ### 5/5 — Heavily underrated *2015-10-21, version 5.1* I absolutely love this app for my iPad.

Excellent design without having to imitate the 70’s physical ones. 5 stars ### 5/5 — Great interface, missing RPN on Apple Watch *2022-04-22, version 9.0.1* This is a fantastic iOS app and works very well.
