  4. [R30] Calculator‰ 3/5 · US Missing One Important Feature: If there is a way to delete the last entry without deleting the entire running tape of calculations- I can’t figure it out. Sometimes you hit the wrong button and there’s no way to erase that without starting over.
  5. [R1] Calculator‰ 1/5 · US Constant Ad Interruption: I used this app for years but now the interruptions with ads make it unusable. I’ve deleted and moved on. Not worth downloading.

  7. [R4] Calculator‰ 1/5 · US Long ads: 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.
  8. [R10] Calculator‰ 2/5 · US Too many ads: I’ve been using this calculator on my phone for years and always loved it, but recently the ads have gotten absolutely ridiculous. 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.
  9. [R5] Calculator‰ 5/5 · US Great Calculator: 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.

  11. [R111] Calculator for iPad! 3/5 · GB Can’t get paid version!: Don’t know how to get the paid version. Why can’t we just pay the cash and have it unlocked?

  14. [R39] Calculator‰ 1/5 · US Ads interrupt calculations: I’ve had this app for years. Suddenly it has featured pop up advertisements that show up in mid calculation with no visible escape button. Time to find a replacement.

  16. [R64] Calculator for iPad! 2/5 · US Unusable with ad bar: I have been using this calculator for several years, and it was my favorite. However, recently there has been an ad bar across the bottom row of keys, and I can no longer use this calculator. I tried uninstalling it and re-installing it.
