About this app

This is one of the few apps that I would actually pay to remove the ads and there isn't an option. There is also backdoor to open the apps you've hidden without opening calculator, at least on Android. Go to the play store and find the manage apps option. From there you can see which apps you have installed and just a simple click on the icon and the 'open' button allows the app to be opened with the passcode. Locking the app does prevent it from being open but once the cat's out of the bag....

Hi! Thanks for your feedback. We understand ads can be frustrating. They help keep the app free and support development. We're considering a paid option to remove ads in the future. Hidden apps are only hidden from your device screen, not the Google Play Store, which is controlled by Google. Your apps and data remain protected. Thank you! 🙏

This is got to be one of the worst ones in terms of ads. I expected ads and knew there will be some but not this bad! Even after waiting 30 for the ad to finish, I get hit with another automatic ad immediately after entering my code in the calculator, forcing me to watch another 30 second ad. If I open an app or photo in the app and then want to switch to another app or something, I have to watch yet another 30 second ad. Luckily I'm on a temporary device and will no longer need to use this.

Hello! We’re sorry if the ads bothered you. The app is free, and ads help cover development and operational costs so we can continue improving it. Normally, you can skip the ads after a few seconds. We truly appreciate your understanding and patience. 🥺

Sitting through a long ad, then waiting for a tiny "Google Play" button to pop up in the corner, so you can go to Google Play then back, to FINALLY turn that button into the option to close the ad is far from convenient. And the fact that you HAVE to have this giant notification to make it work, and if anyone dismisses that notification, nothing is locked anymore, also sucks. Having a calculator in your notifications isn't exactly low-key either, cause NOBODY would need a calculator notification

Hello Nic! We’re sorry if the ads bothered you. Normally, you can skip the ads after a few seconds. To stop notifications on Android, go to Settings > Apps > [Calculator:App Hider&Locker], or other apps you wish to disable notifications > Notifications and turn them off. This will prevent alerts while keeping your privacy intact. Hope this helps!
