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. ### 5/5 — From *2026-04-23, version 5.4* This Calculator app is very easy to use & accurate. ### 5/5 — Douglas *2026-03-26, version 5.4* Outstanding ### 5/5 — Calculator *2026-03-16, version 5.4* User friendly. Thanks. ### 3/5 — Ads *2026-03-14, version 5.4* 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 ### 4/5 — Used to be my fav *2026-03-06, version 5.4* Basic and easy to use I’d give 5 stars if the tap the star thing worked- then today I use it and my phone starts talking!!! After I left the app! I get back to it to see what’s happening and it’s running an ad and apparently it doesn’t care what else you may be doing at the time. You better tell me this is a bug or I’ll start looking for another calculator Phone was defective and replaced. Now seems to work right again ### 2/5 — Not good. *2026-03-03, version 5.4* Too many breakthrough advertising ### 4/5 — Very simple *2026-03-01, version 5.4* This is great. It is super easy to use and very basic. However it would be nice if it had more background options. ### 5/5 — Good Calc. *2026-02-16, version 5.4* I’ve only had this app for about an hour. And it works just great! ### 5/5 — The Best *2026-02-01, version 5.4* Favorite Calculator. Ease of use. The best. ### 5/5 — Easy tool *2026-01-30, version 5.4* Great little tool for easy problems ### 5/5 — Uncomplicated *2026-01-27, version 5.4* Great basic calculator for all the most usual needs. ## Most critical reviews (10 lowest-rated) ### 1/5 — Constant Ad Interruption *2026-07-05, version 5.4* I used this app for years but now the interruptions with ads make it unusable. I’ve deleted and moved on. Not worth downloading. ### 1/5 — 6/6/26 *2026-06-30, version 5.4* Scam Adverts when using it a advert will pop up as f it’s a genuine alert but it’s a scam swipe up from bottom of the screen shut it down and close all apps down scam scam scam be aware ### 1/5 — Long ads *2026-06-19, version 5.4* 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. ### 1/5 — ANNOYING ADS!! *2026-06-05, version 5.4* I just want a calculator! Nothing fancy, just a nice, basic calculator. This has now turned into an annoying ad machine. Deleting it from my phone. ### 1/5 — Calculator *2026-05-10, version 5.4* Won’t clear ### 1/5 — Become unusable *2026-01-30, version 5.4* Have used this app for many years but recently has become unusable due to full screen ads popping up frequently to the point you don’t have time to input a simple calculation. Was ok when it was just small ads at the bottom which did not interfere with using the calculator. ### 1/5 — What the privacy?! *2026-01-16, version 5.4* From real, what is wrong with the world. Why do I need to sign a privacy policy to use a calculator? They are gonna scan my phone & siphon my data to the highest bidder just so I can add up a stack of checks. Garbage. ### 1/5 — Calculator *2026-01-15, version 5.4* Slide over not working after iPad update. Now I can’t use it for my banking. ### 1/5 — Can barely use without getting multiple ads *2026-01-14, version 5.4* Does what it’s supposed to do but would rate higher if wasn’t for the multiple ads every 30 seconds or so do we really need ads for a simple calculator app I mean enough is enough ### 1/5 — Was a nice Calculator App until... *2025-12-25, version 5.4* Have had the Calculator App for about two-three weeks, with the C button instead on a back key button, that the Apple calculator app did away with. Just a nice simple, button in the right spots. All of sudden today, an Ad pops up! Never did since I downloaded the app, until now. And each time I would go back to use it for a quick thing, and the ad comes up each time, before I can touch a button. So what did is what I do when I get interrupted with an Ad, is delete the app. Goodbye... ## Most praised reviews (10 highest-rated) ### 5/5 — Short time user *2026-08-24, version 5.4* I like that it’s free. Easy to use and convenient on my phone! ### 5/5 — Cuda *2026-08-16, version 5.4* Very easy to use. ### 5/5 — Calculator% *2026-08-12, version 5.4* Was a great app but now I started getting ads while working in problems. ### 5/5 — Good *2026-07-10, version 5.4* Great does the job ### 5/5 — It’s huge! *2026-07-08, version 5.4* So far no problems like the other one where there was popups like every second. ### 5/5 — Great Calculator *2026-06-24, version 5.4* 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. ### 5/5 — Stewie *2026-06-21, version 5.4* This calculator is a marvellous item to have to use no worries, no ads popping up. ### 5/5 — Inexpensive, basic. *2026-05-22, version 5.4* Works like a charm! ### 5/5 — Easy! *2026-05-12, version 5.4* Thank you for simple… sometimes we just don’t need 50 choices ### 5/5 — Excellent product *2026-04-28, version 5.4* Works great --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
