Since the upgrade now you have to go into the drop down menu and select “Scientific” before the calculator shows up to be used. What a pain. Definitely not an improvement. -- DarthRanger, 2023-07-11 ### ***** "Noice" Nice -- cha’s macbook air, 2019-10-18 ### *---- "Bad" Ads -- Mainly4s, 2018-09-21 ### ***** "Decent!" Easy to use! -- JAConar, 2018-06-13 ### ****- "Good" Yup pretty good -- Cx zig xyzzy xots dot, 2018-05-01 ### ***** "Great tool" Great calculator -- Iman12, 2018-01-21 ### ***** "Good" Good -- Brian Haberon, 2017-09-17 ### ***** "Upgrades must be paid for, no longer able to see ad" It took some getting used to, but when I first got this app, I was able to unlock additional features for a day by viewing an ad. I thought this was a small price to pay. Now, you have to upgrade. However, I still rate this as a five-star app because there are so many features available even for the free version. The one change I would like to see is a separate Memory store button instead of needing to use M+ to put something into memory. The way it works now, if I want to totally replace what's in Memory, I have to hit MC (memory clear) and then M+ - two keys/buttons, compared to one serving this function in other calculator apps I have tried and on physical calculators. Again, not serious enough to not rate this with five stars, just something that would be nice to have in a future release. -- rslitman, 2017-09-09 ### ***** "Nice!" Easy to use with many features! -- Arp60, 2017-08-25 ### ***** "Frank" Good app with so many features -- Fahrenheit,skins, 2017-08-14 [View all Calculator # Converter reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Calculator # Converter In-App Purchases | Item | Price | |------|-------| | "Joyful skins" | $0.99 | | Periodic Table | $0.99 | | Formula Toolkit | $0.99 | | Daily Calculating | $1.99 | | "Unlock All features" | $2.99 | | Engineering & Financial Calculator | $1.99 | ## Apps Similar to Calculator # Converter - [Calc 2M](https://apptail.io/app/calc-2m-mxdc/united-states) - [ACalc - Scientific Calculator](https://apptail.io/app/acalc-scientific-calculator-Vrjc/united-states) - [Scientific Calculator Standard](https://apptail.io/app/scientific-calculator-standard-Yrjc/united-states) - [Calculator - Unit Converter](https://apptail.io/app/calculator-unit-converter-ZZtc/united-states) - [BCalc - a daily calculator](https://apptail.io/app/bcalc-a-daily-calculator-gfZc/united-states) - [Calculator· - Easy to Use](https://apptail.io/app/calculator-easy-to-use-wELd/united-states) - [Basic Calculator: Classic Calc](https://apptail.io/app/basic-calculator-classic-calc-yELd/united-states) - [计算器 MaxiCalc 免费版 iPad：标准与科学模式，存储器 LCD 显示](https://apptail.io/app/maxicalc-ipad-lcd-TRdl/united-states) - [Calc Pro HD – iPad Calculator](https://apptail.io/app/calc-pro-hd-ipad-calculator-URdl/united-states) - [計算機](https://apptail.io/app/app-HSdl/united-states) ## Calculator # Converter Available In - [United States](https://apptail.io/app/calculator-converter-pSdl/united-states) - [China](https://apptail.io/app/calculator-converter-pSdl/china) - [Mexico](https://apptail.io/app/calculator-converter-pSdl/mexico) - [Canada](https://apptail.io/app/calculator-converter-pSdl/canada) - [Italy](https://apptail.io/app/calculator-converter-pSdl/italy) - [Brazil](https://apptail.io/app/calculator-converter-pSdl/brazil) - [United Kingdom](https://apptail.io/app/calculator-converter-pSdl/united-kingdom) - [Spain](https://apptail.io/app/calculator-converter-pSdl/spain) - [Australia](https://apptail.io/app/calculator-converter-pSdl/australia) - [Vietnam](https://apptail.io/app/calculator-converter-pSdl/vietnam) - [Russia](https://apptail.io/app/calculator-converter-pSdl/russia) - [India](https://apptail.io/app/calculator-converter-pSdl/india) - [France](https://apptail.io/app/calculator-converter-pSdl/france) - [Japan](https://apptail.io/app/calculator-converter-pSdl/japan) - [Denmark](https://apptail.io/app/calculator-converter-pSdl/denmark) - [Greece](https://apptail.io/app/calculator-converter-pSdl/greece) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
