Extensions for MIT App Inventor, Thunkable, Appybuilder and Makeroid

Extensions add special-purpose features to app inventor. They are packaged as aix files and can be used just like other components. If you are interested in one of my extensions, you can contact me and purchase it. After your PayPal payment I will send you the aix file which you can import into your project.

ESC/POS Simple Converter

The ESC/POS Simple Converter enables to send formatted text, images, bar codes and QR codes from App Inventor to a bluetooth thermal printer without the need of having knowledge in ESC/POS programming.

Quick SOrt

The Quick Sort extension provides a fast sorting algorithm for vast lists of numbers or text. It is possible to make an asynchronous call in an own thread.

Object Manager

The Object Manager offers a convenient way of structuring and handling data as objects with attributes.


Barcode Generator

Use the barcode generator extension to generate a full range of barcodes (Codabar, Code 39, Code 128, EAN-8, EAN-13, ITF, PDF417, QR code, UPC-A). You can set the bar color and the background color and save the resulting image to your SD card.

Bluetooth Connector

The Bluetooth Connector extension provides an asynchronous method for connecting a bluetooth printer in the background so that the app doesn't freeze while waiting for an answer.



Happy Inventing!
