The advantages of the annual subscription:

 - it entitles you to free SDK version updates as long as you have an active subscription;

-  it allows you to host AR experiences in Wikitude Studio and link them in your app, including 100GB storage space;

- while you have an Active SDK Subscription, you can renew your Trial Key after each expiration. Find out more in the dedicated FAQ

On the other hand, the one-time fee does not include SDK version upgrades, no hosting feature and only 50 GB storage in Wikitude Studio.
