I would rather say that it is better to use some ad blocker for that. If you’re Ok to pay for additional calculator functionality but don’t want to pay for disabling ads, you can use AdLock. AdLock works with any calculator for iPad; no ads are guaranteed. Moreover, it not only removes ads from calculators but also clears most ads from other apps and games. When it comes to Safari, the ad-blocking functionality is available for free. Check out for more info https://adlock.com/blog/best-calculator-apps-for-ipad-no-ads/
