Had to look all over to find a memory calculator that wasn’t written by retards who never understood 3rd grade math. -- StopBadApps, 2022-04-15 ### ****- "Your math is off" 267.46+176.97 = 444.4299999999 Really? And where is the +/- button? Could you please add a unit conversion calculator as well? -- Dermit Dad, 2019-12-22 ### ***** "Solid Basic Calculator" This let’s you fully type out multi-expression math problems. It can’t do anything too fancy, it’s just a solid replacement for the basic calculator. Also, if you close the app, the previous expressions stay in your history (I’m not sure about restarting the phone though). -- LilacDoe, 2019-11-18 ### ***** "Has best tape feature" Love it -- Oplumbing, 2019-11-16 ### ***** "Love It" I love the previous calculations stay visible in case I need the review them again. -- franhoward$, 2019-10-01 ### ***** "The calculator I was looking for." This is the calculator I was looking for. I recently subscribed to the ‘removed ads’ version because this is the one calculator app that had the features I was looking for. For example, I can easily see the last inputs because there is a history panel which you can scroll up and down with the swipe of a finger. I also enjoy the ‘last’ button feature that allows me to do calculations in where I can use my previous calculated sum—multiply/subtract/etc it by an even prior sum, easily accessible via the history feed. Thanks. -- blanktimes, 2019-09-07 ### ***** "Finally no need to rotate." Thank you for creating the only calculator app that gracefully gives you more options without having to rotate the screen awkwardly. Coming from a TI 83 background, this is perfect for basic scientific calculating needs. -- GR747, 2019-07-22 ### *---- "Bait & Switch" As usual they sucker you in by making it free, then they overwhelm you with ads then if you want to get rid of the ads you have pay. So I just rid of the app. -- H Inc, 2019-03-24 ### ***** "Perfect basic calc app" This is a great calculator app with a log of all your calculations that you can reference & reuse. Very much appreciate that it’s free! -- grsgrk, 2018-01-22 ### ***** "Easiest calculator I’ve ever used" No directions needed. Easy to use -- Larry Null, 2018-01-07 [View all Calculator × reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Calculator × In-App Purchases | Item | Price | |------|-------| | Premium Yearly | $4.99 | | Remove ads | $11.99 | ## Calculator × Discovered Keywords -
