AppyBuilder is a commercial version of MIT App Inventor that, for a monthly subscription fee, provides access to many additional components and features. Some of these features include monetization services that work with advertising networks to display ads with your apps, plus unique features like SQL Lite and the Android Material Design user interface. You can also add in-app purchases.
There is also a free version that operates similar to MIT App Inventor. You can set up your free account at the Appy Builder web site or sign up for a subscription account with added features.
AppyBuilder is based on MIT App Inventor – if you know how to use App Inventor, you’ll find AppyBuilder very easy to use. The company behind AppBuilder also does custom app development and mobile web site development.

I’ve played a bit with the “free” version but I could see buying a monthly subscription to access several of their enhanced features. Their lead architect also has a blog including this tutorial on how to use their components to access the web, camera and upload photos to a server using App Builder.
Since I moved the web site from my own server over to the WordPress platform, you will often see posts authored by “Coldstreams”, or sometimes “AppinventorPlus”, rather than my name, EdwardM, that appeared on the old web site. I have 4 separate accounts on WordPress and set them up so that my Coldstreams account can update any of the blogs, including this one. Most of my posts will likely appear with the “Coldstreams” name, but it is still just me 🙂 … EdwardM
