I've noticed that some apps I have downloaded on my iOS devices from the App Store are supported by ads. Although I used to be 100% anti-ad, I see the value since I use ads in a limited capacity myself. I have also noticed a few apps that offer the option to remove ads with an in-app purchase. If you're an app developer and you use ads, please offer an option to remove them with an in-app purchase. That would be wonderful. If it's not there, I probably won't use your app. I'm happy to pay for no ads.
