As of today we are announcing that Begin will be a free app going forward. We will still offer an in-app purchase to extend Begin. Right now users can purchase additional themes at $0.99 for the lot, but the app will be free for all to download and use.
Look for the 1.1 update (coming soon) to add another nice perk for those who have, and will, purchase the app extension.
Ben and I both love developing Begin, and our sincere hope is to continue to make Begin great for all users. At $0.99 for entry, we wouldn't have been able to keep Begin alive. I hope you can understand why we made this decision.
Thanks for your support!
