  1. [R8] Calculator‰ 5/5 · US Inexpensive, basic.: Works like a charm!
  2. [R11] Calculator‰ 5/5 · US Easy!: Thank you for simple… sometimes we just don’t need 50 choices
  3. [R17] Calculator‰ 5/5 · US From: This Calculator app is very easy to use & accurate.
  4. [R23] Calculator‰ 5/5 · US Calculator: User friendly. Thanks.
  5. [R1] Calculator‰ 1/5 · US Constant Ad Interruption: I used this app for years but now the interruptions with ads make it unusable. I’ve deleted and moved on. Not worth downloading.
  6. [R3] Calculator‰ 3/5 · US Ads: I realize you need to make money, but EVERYTIME I hit total an ad comes up. This used to be my favorite calculator. Time to move on
  7. [R4] Calculator‰ 1/5 · US Long ads: Almost impossible to use. This app has now incorporated long ads which begin shortly after opening. No way to close the ad without seeing it the full way through.
  8. [R6] Calculator‰ 3/5 · US Ad monster gets bigger and bigger: Worst part is when the ads popped up, you couldn’t get the pop up to go away to get back to the calculator screen. Had enough of it, changed to a different calculator program
  9. [R5] Calculator‰ 5/5 · US Great Calculator: I love your app, thankyou! Just wanted to mention that some of your ads go to a "url not found" page and also when I click "legal," it goes to a blank page.
  10. [R70] Calculator₊ 1/5 · US I have a problem: Download and liked it so much paid for it . Got a new phone and I could no longer download and use what I already paid for.
  11. [R99] Calculator₊ 3/5 · GB BRING BACK KEYBOARD SUPPORT: FOR THE LOVE OF GOD PLEASE!!!! I AM RE-SUBMITTING THIS REVIEW as after I have waited YET ANOTHER few updates and still the keyboard support has not been reinstated. Not everyone uses their iPad solely touchscreen. I am a desk worker who uses keyboard and mouse, it used to work flawlessly and was removed? Why??? PLEAE RESPOND TO THIS REVIEW DEVELOPER! I have been using
  12. [R10] Calculator‰ 2/5 · US Too many ads: I’ve been using this calculator on my phone for years and always loved it, but recently the ads have gotten absolutely ridiculous. If I’m trying to remember numbers to calculate, I’ll forget them before I can use the calculator because it jumps to ads as soon as I open the app. I don’t know what changed but this calculator has gone from awesome to useless.
  13. [R61] Calculator₊ 1/5 · US For a Calculator?: Why would I ever pay a reoccurring subscription…even a penny…for a calculator. Get out of here with this $5.99. 🙄
  14. [R73] Calculator₊ 1/5 · US Seriously?: I accidentally tapped on something and it wants to charge me six dollars a month for a calculator? This thing does nothing that you can’t get free very easily.
  15. [R79] Calculator₊ 1/5 · US sucks.: you will have to pay for it, just get any other calculator please.
  16. [R82] Calculator₊ 2/5 · US Not even remotely worth it.: $60/yr for a calculator with scant more features than Apple’s own calculator? No thanks. This app at most is worth a single purchase of about $2 and certainly NOT worthy of a subscription. The dev is probably relying on the fact that many people forget about their subscriptions so the dev can quietly pocket undeserved money. This isn’t what Steve Jobs had in mind w
  17. [R63] Calculator₊ 3/5 · US Don’t recommend: This calculator is not helpful because you have to pay for some stuff and there are ads VERY annoying 😤and I would have put 5 or 4 stars.
  18. [R66] Calculator₊ 3/5 · US Works great, why do I need ads and other useless content?: Works great, why do I need ads and other useless content?
  19. [R75] Calculator₊ 3/5 · GB Too much adds around the screen but works: Lower down on the ads a bit because I accidentally always click them but it works fine just too much ads thank you
  20. [R85] Calculator₊ 1/5 · US ADS: I don’t like ads,there are so much ads!
