While Air Horn is completely free to use, it is supported by in-app advertising which some users may wish to remove. Depending on which platform you are using Air Horn on, you can generally choose to remove advertising from within the app itself. However, buying a license key here directly from Ape Apps does come with some advantages:
- You will recieve a downloadable license key file which can be used to unlock/upgrade Air Horn on any supported platform.
- You will also be able to remove advertising on the online/HTML5 version of Air Horn on Ape Web Apps.
- Your key will continue to work everywhere*, even if you switch platforms. If some awesome new platform comes out that we haven't even heard of yet and Ape Apps releases Air Horn for it, your key will work there too!
- Purchasing a premium upgrade key for Air Horn directly from Ape Apps costs just $0.99, and gives you lifetime premium ad-free access across all platforms!
After completing your purchase through PayPal, you must
follow the "Back to Ape Apps" links that it gives you in order to automatically generate your license key. Otherwise, you will need to contact firstname.lastname@example.org
with your order reciept and confirmation details in order to complete your purchase.
