Android Marketing: Using coupons to give away paid Android Apps

This looks like a neat idea. A nice extension would be to allow for a QR code entry that would invalidate itself over some criteria.

Using the free version + paid unlocker approach (<a href="http://www.marvinlabs.com/2011/01/sharing-code-full-lite-versions-application/" rel="nofollow">http://www.marvinlabs.com/2011/01/sharing-code-full-lite-ver...</a>), you can gift the paid version by sending just the unlocker APK to the user. Since all the functionality is in the free version from the market, they'll get updates normally. That said, this is really cool - I was thinking of building something like it for my applications.

I was actually just wondering the other day if this existed for either (Google or Amazon) Android market.<p>This seems like a good solution until they implement it into the market itself.

I didn't dive deep into the source code.<p>Does it invalidate a coupon after it's used?<p>What would happen if I get a new phone? Would I need to get a new coupon?

We are working on a SaaS that solves exactly this problem combined with some additional things except you don t have to enter any coupons, its completely managed by the back end.<p>Looks cool though.

Sounds like a cool idea. Thumbs up!

Could the same thing be done for iPhone apps or would Apple not allow such things?
