All I want is a calculator that will multiply numbers for me. ### 2/5 — Where’s my comma?? *2026-06-12, version 8.1* Not sure what happened, but when I add 6 digit numbers, the comma has disappeared!! ### 2/5 — Update *2026-02-15, version 8.0* I don’t like not being able to see the numbers when subtracting. ### 4/5 — Good basic calculator *2026-01-30, version 8.0* Easy to use, no ads. Basic functions only, no scientific functions. ### 2/5 — Stop the ads *2026-01-19, version 7.2* The pop up ads are annoying. When I’m trying to input an equation, it ruins the math. I don’t see how to turn them off. ### 2/5 — Great app but Please fix this bug *2025-11-25, version 7.2* I use the calculator most of the time, and when clicking on any of the Bottom five buttons, the app instantly crashes ### 2/5 — Basic math *2025-10-20, version 7.2* Not interested in purchasing anything else. ### 5/5 — Straight to business *2025-08-11, version 7.2* When I open this app I am not watching some ad, I am able to work while it’s still on my mind. ### 4/5 — Good Calculator *2025-05-07* I really like this calculator vs. the default calculator that was on my iPad. The reason I changed was that this calculator is ad free and the default calculator would pop up an ad after every calculation. Very frustrating. The only reason I gave it 4 stars, is that I use this app as a slide over while in other apps and if I’m doing more than 2 calculations, I can’t see what all my entries are until I press the equal sign. As for other reviews that say it’s not accurate in calculation, such as 6+(9x5), they’re wrong. The correct answer is 51 and this calculator also comes up with 51, not 75 as someone pointed out. You don’t need the parentheses as someone stated. Just enter 6+9x5 and the calculator knows to do the multiplication first. **Developer response:** Thanks for the great review! We’re glad you enjoy the ad-free experience and appreciate the feedback! ### 4/5 — Good Calculator *2025-05-03* I really like this calculator vs. the default calculator that was on my iPad.

Sans annonces, avec plusieurs fonctions. On paye une fois et on en a pour notre argent. ### 5/5 — The Absolute Best *2025-02-05* I first loaded this on my ipad and loved it. Now, with the latest iphone software update, they have really screwed up their calculator app. I am so glad that I knew about this wonderful app. Easy to read, easy to input, visually well designed. I so appreciate the creator of this app. Thank you. **Developer response:** Wow! 10 stars is wonderful! Thank you for the excellent review and keep enjoying the calculator app! ## Most critical reviews (10 lowest-rated) ### 1/5 — Stops working after adding or subtracting 3 times *2026-03-16, version 8.0* I’ve used this for years and now it doesn’t keep a running balance. I can add or subtract e times and then it stops without continuing on ### 1/5 — Can’t figure it out. *2026-02-12, version 8.0* When hit total. Takes me back to where I started ### 1/5 — ADS *2026-02-04, version 8.0* This is supposed to be an ad free Calculator• there are banner ad of this calculator ### 1/5 — Change is bad *2026-02-02, version 8.0* The new appearance with the square root symbol is in a bad location. ### 1/5 — Missing order of mathematics *2025-04-28* This is missing parentheses to calculate the proper numbers first. If I want 6+(9*5)=51 it doesn’t understand basic laws of math, it does 6+9 =15 and then multiple by 5 (75). There are cases where like on a tax form you’ll add a bunch of rows then take a percent .1 and then multiply it by say 2. You want it to calculate it in the proper sequence. This will not! This is really an “adding machine” for free. If you have one calculation to do you're fine. All the other things for loans, mortgage, interest and such require paying a small amount of money but being the basic laws of math aren't followed with the calculator, I don't trust anything else. ### 1/5 — No currency conversion *2025-04-12, version 7.2* Where is the currency conversion everyone is raving about? ### 1/5 — Dr Michael *2025-02-04, version 7.2* This App is a total waste of anyone’s time! ### 1/5 — Bank *2024-11-14, version 6.3* Horrible calculator. It requires payment each time you use it. ### 1/5 — Payment *2024-11-07, version 6.1* The reason I give this calculator a 1 star is because It keeps charging me when I paid for it in 2023. Other wise it’s okay. ### 1/5 — Sketchy *2024-11-05, version 6.0* Suddenly asking for permissions that it has no business asking for. It’s a calculator, why do you need notifications? ## Most praised reviews (10 highest-rated) ### 5/5 — Love it *2026-06-25, version 8.1* Better than Apple’s BS Calculator ### 5/5 — Luv it *2026-05-31, version 8.1* Best Calc out there ### 5/5 — A good game *2026-05-27, version 8.0* It helps me a lot, and I learned a lot ### 5/5 — I’ve tried a few *2026-03-28, version 8.0* Truly the best available. ### 5/5 — So easy *2026-03-21, version 8.0* Simple to use and no advertisements!
