  1. [R2] 1/5 · US Fed Up!!: I have ALWAYS used this calculator app, but I have had it! I can’t take the Quince ads any longer! Quince is a fine retailer, but I cannot get out of their ads and it is EXTREMELY ANNOYING!!
  2. [R4] 1/5 · US Ads: Was trying to use this and ads kept popping up…on a calculator app like rly -.- Deleted it so fast
  3. [R12] 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.
  4. [R18] 2/5 · US Ad pop ups ruined this app: I can’t get the app to work any longer. An add popped up and took over when I tried to use it. So I clicked out of the app and back on, the ad is still there. App no longer works. Big fix needed.
  5. [R17] 1/5 · US Crazy app: This app keeps saying I’ve been hacked over and over again,don’t download
  6. [R76] 1/5 · US What is with these ads!!!: I have used this calculator for years and years! Now all of sudden you are running Carumba ads and others. I can’t X out of these ads! This is so frustrating! I can’t get rid of these incessantly long ads. So I am going to delete this calculator and try something else. I understand that ads bring you revenue but give your users a way out, please.
  7. [R116] 2/5 · US Ads that force downloads: Just got an ad that wouldn’t go away unless I downloaded an app. Never going to happen. Don’t get this
  8. [R174] 1/5 · US Terms of service... For a calculator?: Ridiculous
  9. [R185] 1/5 · US if the product is free, you're the product: information gathering. true that there is no direct monitary cost to use this app, they just want to collect data. personally i don't see why any calculator is not an offline app.
  10. [R243] 1/5 · US Read the privacy policy: The app is advertised for ages 4+, but the advertising privacy policy states users must be 13+. I’m trying to find a calculator app for my child that isn’t full of intrusive ads. Apparently this doesn’t exist for iPad.
  11. [R323] 1/5 · GB Unusable due to cookie policy: Horrible cookie notice that requires hours to go through and deny all the so called legitimate use. Where's the single button to deny? App itself is just ok but not worth wading through the cookie settings, so removed this. There are plenty of alternatives.

  21. [R24] 5/5 · US I got it. A basic calculator!!: I just needed a basic calculator. Too many of them were fancy and wanted you to pay a monthly subscription. Not this one. So grateful to have found it.

  23. [R29] 4/5 · US No ad: found my basic calculator with no ad. Since iPhone calculator change little bit and I don’t like its.
  24. [R51] 1/5 · US Does not perform sums of products properly: Tried to do T=a*b+c*d which did not give same answer asT=a*b+d*c and neither were the right answer. For example, if perform multiplications before summations (usual practice if parentheses not used), then 2*3+5*7 = 6+35 = 41 In this app 2*3+5*7=77 And 2*3+7*5=65 It looks like app does ((a*b)+c)*d instead. Should let the user know the precedence of
