Smooth and fast operation and easy copy/paste feature makes it quick to redo or correct errors. I like the TI calculator look to the color scheme and button placement. Plus I'm always down to help a fellow UTA Maverick (Class of '12). ### 5/5 — Nothing beats this. *2021-08-28, version 1.1.2* Awesome work! Finally, a calculator that works quickly, along with a clean and friendly UI. Significantly better than the default calculator provided by Apple. Hoping for an iPadOS and macOS release. One request: I would love to see dark mode eventually added. Something that doesn’t sound important but more convenient when using the app at night. ### 5/5 — My new calculator app *2021-08-10, version 1.1.1* Great app design, a night mode would be cool but no dealbreaker by any means. My new go to calculator ### 5/5 — YOU DID GREAT!!! *2021-08-08, version 1.1.1* This is awesome and wonderful and EXTREMELY appreciated! ### 5/5 — Wonderful calculator. *2021-08-05, version 1.1.1* Great work Paul on this calculator app. Find it much easier to input into then the default calculator. I do have a request for a feature, maybe make it a toggle if others don’t like it, but maybe you can make hitting enter on a blank line re enter the previous input. For instance if I had a^2 every time I hit enter it would square the previous output. ### 5/5 — ILL *2021-08-05, version 1.1.1* Great app ### 5/5 — Very good *2021-08-05, version 1.1.1* Very good! ### 5/5 — Excellent *2021-08-05, version 1.1.1* True to its word, did not use ads or steal my data. Tactile feedback is awesome and lots of quality of life features too! ### 5/5 — Great calculator *2021-08-05, version 1.1.1* This is a very good free scientific calculator. Only suggestion is to make the calculator send you to a newline after an overflow error or invalid operation. ### 5/5 — It just makes sense *2021-08-05, version 1.1.1* Hands down one of the best calculators I’ve found. ### 5/5 — Well done! *2021-08-05, version 1.1.1* This app does the math! CPSC for life. ### 5/5 — 👍🏼 *2021-08-04, version 1.1.1* Its cool how it keeps a little history log of the calculations like a graphing calculator, nice touch. The little vibrations when i click the button are a plus. Easy to use! ### 5/5 — Great app *2021-08-04, version 1.1.1* Great app just wish there was a themes menu or a dark mode. ### 5/5 — Easy to Use *2021-08-04, version 1.1.1* The UI is very nice and all of the important calculations are visible to the user in portrait view. ### 5/5 — Seriously the best *2021-08-04, version 1.1.1* Don’t waste your time with any other calculator app. This is the best one. My life is so much better since I downloaded this!! ### 5/5 — Functional and Practical *2021-08-04, version 1.1.1* This is genuinely the cheapest and overall best option for a calculator. Absolutely no ads, the layout is super concise, and the math is quick. My only suggestion is changing the color of the ‘clear’ button, and maybe varying the colors of the ‘delete’ and ‘menu’ button. I find it easier to take note of specific details when the font is either bolded, color coded, or both. It’s just a personal preference, but I think this small change could really perfect this calculator. ### 5/5 — Great calculator app *2021-08-04, version 1.1.1* Awesome calculator. I use the default calculator all the time and I never liked how there was no history. This is great! Thanks. ### 5/5 — Great calculator! *2021-08-03, version 1.1.1* Simple and works as expected. No ads, no fuss. We need more things like this. ### 5/5 — Hook em *2021-08-03, version 1.1.1* Great app. Hook em horns. Keep at it! ## Most critical reviews (10 lowest-rated) ### 5/5 — This is the calculator app I have been needing! *2023-10-02, version 1.1.3* 10/10. Very powerful and user friendly. Apple should buy this and make it the default calculator! ### 5/5 — The Best Calculator App *2023-09-22, version 1.1.3* This calculator is so simple to use! The best thing, is that I can see everything I’m doing, with Apples calculator I can’t do that. This app also has a very clean design and I have used it for 2+ years and have not had any problems with it. Keep up the great work! ### 5/5 — Love the developer, wish I could hug them *2022-09-04, version 1.1.3* This is legit the best calc app for basic operations, better than the default apple calculator. I saw the developer’s post on Reddit a while back asking to check the app out. I honestly thought it was gonna be crap, but I was completely wrong. To the developer, keep working on this calc project and adding more operations to the point where this app has as many operations as the default apple calc. ### 5/5 — better than calculator! *2022-09-04, version 1.1.3* amazing app! ### 5/5 — I use it daily for work. *2022-08-09, version 1.1.3* Easier to open this up the. Grab my calculator for my engineering work. Requesting a copy paste option. Would be helpful to be able to snag large numbers and paste them. Just to clarify, I mean from outside the app. There is currently no ability to copy from outside the app and paste the number in. ### 5/5 — The only normal calculator app on mobile *2021-12-31, version 1.1.2* No profit motive, no designs/features drawing you in, just a calculator app made by a college student for a project. No strings attached. Will forever be my mobile calculator. ### 5/5 — Does what it says it does *2021-10-11* Clean simple interface. Ad free. Will be great to see the iPad version Good stuff. ### 5/5 — Where have you been all my life! *2021-10-11, version 1.1.2* Tried many calculators and none met my standards. This is just what I need!! Thank you! ### 5/5 — No Ads. Clean UI *2021-10-11, version 1.1.2* Simple and easy to use. ### 5/5 — Yes! *2021-10-10, version 1.1.2* It’s a calculator. It loads quickly and works perfectly.
