Thunkable

Thunkable works almost exactly the same as App Inventor with these differences:

• It can create both iOS and Android Apps
• It has a live preview built in to the site however it is limited to certain functions.
• The testing App that can be downloaded to your phone accesses the files directly from your web log in. You do not have to be on the same network.
• It does not provide lessons or curriculum, at this point. - It does provide project examples and templates
