[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!!!
[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.
[R55] Calculator₊ 5/5 · US Pleasant overlay: This app has a very pleasant overlay and ease of buttons for calculations. I enjoy the app.
[R36] Calculator₊ 3/5 · GB Missing basic feature: Just adding my voice to the chorus of those lamenting the absence of the 'constant' function. Apps which seek to replace hardware usually match or exceed the performance capabilities of that hardware. The constant function has been a feature of even the cheapest and least sophisticated calculators since they emerged in the 70s as I recall (my Dad brought one home from work,

[R60] Calculator₊ 1/5 · US Crashes constantly after new update: This is a calculator that charges you a weekly subscription to use it! A calculator 😂. Even after you pay there are constant pop-up ads every few 30 secs.
[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
[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 doesn't display in the answer line; it just shows "0e0." You have to tap on the calculation history to see the actual result. Please fix this; it's quite inconvenient. · translated
[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. 🙄
[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.
[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
[R50] Calculator₊ 1/5 · US $3,120: That’s how much this calculator will cost you for the first 10 years. $6 a WEEK for a calculator?
[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.
[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
[R7] Calculator₊ 1/5 · US Just got the thing: Why u demand review? Just downloaded and opened for first time.
[R33] Calculator₊ 3/5 · GB Chloe‘s advice: I like it but why is it so special and you keep asking me to rate it and give reviews but I am certainly not I’ve already given you three stars and that’s enough
[R61] Basic Calculator+ 1/5 · US Blocking calculator: Now it keeps blocking the calculator and keeps an ad up, trying to force me to get an app to scan your phone on an iPad.
[R63] Basic Calculator+ 3/5 · US Please reduce the ads: The basic calculator works great, but many times now, every time I try to remember a number to put into the calculator I find myself trying to get out of the ads first . These popups have progressively gotten to the frustration point to the user. I do realize that income is necessary and that comes from the ads, but all it does is make me want to not purchase from those comp
[R70] Basic Calculator+ 1/5 · US Horrible: Loaded with adds. Locks up constantly.
[R73] Basic Calculator+ 1/5 · US Was great before ads: Loved it, now ads pop up right in the middle of a calculation
[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
[R48] Calculator₊ 1/5 · US Misleading: This app uses misleading tactics to force you to pay for it. Buttons like “continue for free” that bring you direct to the subscription tab. Weird pricing, $.99 per month but one button is like $5 per month. I wanted to try the app, and if it functioned well I was going to purchase. I only made around 5 calculations and it locked me out. I have no problem paying for something but I wil
