  1. [R3] 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.
  2. [R17] Calculator₊ 4/5 · US Great Calculators: This App Has Great Calculators And Features Such As That It Allows You To Upload A Math Problem Via Photo, For A Price; My Only Issue Is That That Price Is Too Much For An App That I Use On Occasion. I Already Have ChatGPT And So Do Millions Of People, So The Price For This App Is Not Worth It. If It Were, Say, $25 For A Yearly Subscription, Then Yes, Definitely Would Subscribe.
  3. [R23] Calculator₊ 5/5 · US Effective and efficient.: As a business leader and Management Consultant, This is a great application. It does all science related processes and various non-scientific tasks well. Quality sustained; just an overall well rounded elementary tool. Highly recommend it!!!
  4. [R24] Calculator₊ 3/5 · GB Calculator: It’s not the best but it does calculations the way AI does.
  5. [R2] Calculator₊ 5/5 · US Appreciative: Large Fonts Are Very Helpful!
  6. [R14] Calculator₊ 5/5 · US App bug: I genuinely love your product and have been using the paid version for several years, but for about a month now, an annoying bug has appeared: if the answer to a division problem is a repeating decimal, it displays as "0e0" in the answer line. You then have to click on the calculation history to see the actual result. Please fix this; it's inconvenient. · translated
  7. [R16] Calculator₊ 2/5 · US BROKEN running as a side-Widget: As side-screen widget.. Currency decimal / comma usage is wrong. Also, number entry severely lags responding as widget. Both work fine only when NOT running as a side Widget. iPadOS26. ** Currency usage set for “System Default”, which for me is decimal for fraction, and comma for thousands. Using as Widget the calculator shows the opposite of that. ** Numeric e
  8. [R20] Calculator₊ 5/5 · US Always use this app!!! Easy to use and have had fo many years!: You will love it
  9. [R30] Calculator₊ 3/5 · GB This is good! But why did I change my mind on the rating??: This app helps me a lot!! But it has a few bugs….. When I clicked on the 5 it crashed so I clicked on 1 and crashed AGAIN!! It takes up ALOT of space! If your device is good with a lot of space… I would recommend getting this!! But it’s very laggy….. When my brother used it he got rid of it for some reason but he did not tell me why he g
  10. [R1] 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. 🙄
  11. [R4] Calculator₊ 1/5 · US Not Worth Your Time: Shouldn’t have to sift through a million pop ups for a calculator app just to be able to use it. The payment screen for the different memberships also seems intentionally deceiving in my opinion with their “continue for free” button leading you to checkout for their free trial + subscription and the continue without adds option barely visible in the upper corner. Do better. Un
  12. [R13] 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.
  13. [R22] 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
  14. [R10] 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.
  15. [R39] 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
  16. [R70] Calculator for iPad₊ 1/5 · US Double charge?: They want you to pay 1 fee to use on iphone and another to use on ipad…even on same apple account. Not ok
  17. [R88] Calculator for iPad₊ 1/5 · US Selling upgrade that doesn’t work: Have used the app for years and the out of the blue you have to pay a subscription fee to unlock the history. Ok, but I have paid twice now and still can’t see my history. Con!!
  18. [R6] 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. [R15] 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
