Recurring themes

Ads negative
The most prevalent complaint is the overwhelming number of ads, including full-screen pop-ups that interrupt usage, appear upon app switching, and make the calculator nearly unusable. Many users express frustration that a basic utility like a calculator requires such aggressive monetization.R1R11R20R28
Monetization & Subscriptions negative
Users are highly critical of the app's monetization strategy, which includes requiring subscriptions to remove ads and unlock features like calculation history. Some report being tricked into paying or double-charged, viewing the practices as predatory, especially for a calculator app.R5R6R23R34
Usability & Performance negative
While the core calculator function generally works, the constant ad interruptions severely impact usability. Some users also report issues like the currency converter opening by default, inability to correct input errors, or the app becoming stuck, contradicting the developer's claim of 'running smoothly'.R11R29R59R77
Core Functionality positive
Despite the issues, a segment of users still finds the calculator effective for performing basic and complex mathematical computations, appreciating its reliability and the ability to see input history.R12R19R37R42

Who it's for

This app is for users who need a calculator on their iPad and are willing to tolerate frequent, intrusive ads or pay a subscription to remove them R1R5R66. It might appeal to those who value a calculation history feature R64 and find its core math functions reliable R37R42. It is NOT for users who expect a clean, ad-free experience from a basic utility, are sensitive to aggressive monetization tactics, or prefer the default calculator experience found on iPhones R2R20.

Evidence note: The recent reviews skew heavily negative, primarily due to the overwhelming presence of ads and monetization strategies. While a few positive reviews exist, they often acknowledge the ads or focus solely on the calculator's basic functionality, sometimes in contradiction to the overall sentiment.

  7. [R37] 5/5 · US Dependable: Every time I need it, it’s always there. Never down. Never disrupted. Always ready for whatever mathematical query I may have.
  8. [R105] 5/5 · US Love this Calculator App for Many Years: I love this app, served me for many years
  9. [R1] 1/5 · US Ads galore: This used to be a decent app, but now you cant do anything without a pop up ad. This is a calculator! why the hell are there ads!?
  10. [R11] 1/5 · US How extremely annoying to use: The calculator works wonderful but the ads that keep popping up, make it literally impossible for you to use. I hate it. I totally hate it.
  11. [R28] 1/5 · US Too many Ads: Too many ads, can’t even do a simple calculation before one starts playing and you can’t clock out of it even if you wait for it to end. Terrible!
  12. [R55] 3/5 · US Ads kill this app: I wanted a simple calculator for my ipad since apple doesn’t have it as an option (for some reason??). This one was great but having ads not only present but take over the whole screen in a pop up that you have to wait a few seconds to click out of make it unbearable. I’d rather just create a homepage shortcut to a webpage calculator 🙄
  13. [R5] 1/5 · US Fruity, requires in app purchases get rid of ads.: Fruity, requires in app purchases get rid of ads.
  14. [R53] 1/5 · US Ad!: You have to pay to remove ad :(
  15. [R66] 1/5 · US Garbage app: This is app is utter garbage. It is a calculator app. It wants a $1 per week subscription to remove ads. If you don’t then every time you switch to the app, not just open it, switch to it back and forth from one app to another, it plays more ads. I understand that developers should be able to monetize their work, and for a quality calculator app, I would gladly pay the few dollar on
  16. [R115] 3/5 · US Good but maybe needs to be better?: The adds are anoying and i dont wanna pay for no adds
  17. [R6] 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
  18. [R23] 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!!
  19. [R34] 1/5 · US Scam: Tricked me to pay
  20. [R36] 1/5 · US Predatory. Tries to trick users into subscribing.: Predatory practices. Tries to immediately trick the user into subscribing at either price point. Says no ads but displays ads. Breaks App Store rules. These developers are no good.
  21. [R26] 1/5 · US Disappointing: The calculator function works fine, but stop with all the ads and gimmicks that pop up in the middle of trying to do a calculation. It doesn’t do it on my iPhone. It only does it on my iPad and it’s really annoying.
  22. [R29] 3/5 · US It’s meh.: Pretty helpful app for needing to study math but Out of nowhere you get an ad for calculator… WHILE USING CALCULATOR Fix that now
  23. [R30] 3/5 · US The ads: The ads are so annoying I’m trying to work and then I accidentally click on one of those ads, do you need them?
  24. [R62] 2/5 · US Keep interrupting me: App has been open for less than a min and I’ve gotten 3 interruptions. 1 ad, and 2 pop ups asking for a review. F off
  25. [R59] 1/5 · US Calculator: This used to be a calculator and now it’s stuck in a currency equation and can’t seem to come out of it. Not even a backspace function is available. I’m deleting this app. It doesn’t work!!!!
  26. [R77] 1/5 · US The currency converter shows all of the time now: I have paid for this calculator going on three years. The latest calculator for iPad Pro 12.9 6th generation always opens to the currency converter unnecessarily. To use the regular calculator I need to flip back to the regular calculator every time I use it. I contacted support about the problem, sent video of the issue. No fix yet.
  27. [R80] 1/5 · US Stupid: It keeps making me to currency
  28. [R129] 4/5 · US Waste of money.: Doesn’t allow you to correct mistakes in a long string of numbers without having to delete the entire string and start over. Waste of money.
  29. [R180] 3/5 · US Mediocre: Performance wise, the calculator is sub-par. There are definitely better apps you could get that don’t require a monthly subscription just to remove the ads. Also, this may just be my blatant ignorance, but there’s no feature to use fractions in your equation. I personally think you’d benefit much more from getting a scientific calculator instead of this one. In my opin
  30. [R20] 1/5 · US Ads on a CALCULATOR?: WHYY?? Just why put ads on a calculator if you dont like ads dont download this
  31. [R7] 4/5 · US Works Fairly Well: I use it almost every time I need a calculator. Some ads but you can upgrade away from ads. It overall works fairly well. You should see for your self!
  32. [R2] 1/5 · US No: A calculator now needs ads, terms of service, privacy policy, and a FORGET ME button, which implies they are tracking your data, and are. For a calculator. I’m switching to a more default feel app.
