We are planning to distribute the app for free as a reward for crowdfunding. However, after doing some research, we discovered that there was no way to distribute it for free on Apple’s App Store.
We thought it would be possible with a promotional code distributed for the media, but there is a limit on the number of copies distributed and there is an expiration date, so it cannot be used as a reward. There are other ideas on the internet, such as using a volume license, but they seem difficult to use.
The only option currently available is to set up a subscription plan and distribute offer codes for it. The upper limit on the number of distributions is high and can be set without an expiration date. Apple’s website also states that it is “suitable for large-scale campaigns that envision mass distribution.”
We will contact Apple in the new year to decide on a reward policy.
