Hello! The app includes an option to remove ads — and you actually don’t have to pay to use it. It’s also clearly stated that ads are shown before starting the test. Unlike many other apps, this one doesn’t bombard users with aggressive or constant ads. Yes, an ad plays before the test starts, but that’s really the only reasonable time to show it. If you prefer not to use the ad removal options, I just ask for a bit of understanding. Have a great day!

We don’t get to hear such good news every day. I’m really glad it worked for you!

Hello! I'm sorry to hear you're having issues with your phone. The app doesn't change any system settings; essentially, it's no different from playing a game on your device. Therefore, it shouldn't cause any problems, but I'd like to help you. If you could email me with detailed information about your issue and attach a screenshot taken from another phone, I'll do my best to assist you.
