Sample Project now available

We’ve published a GitHub repo with a working sample project.

Without needing to do any modifications, you can upload it to VoltBuilder, build an apk, then run it on your Android device. It’s a minimal HelloWorld style app.

Feel free to look at how it’s set up. Compare it to your project to see if it is structured properly. Starting a new project? Go ahead and use it as a template.

The project will also build for iOS, but you’ll need to be signed up for Apple’s Developer program and create certificates for it.


What VoltBuilder Does

VoltBuilder is a web front end for Apache Cordova. It builds native executables (.apk and .ipa) for Android and iOS from web apps. These executables can be augmented with native code plugins which extend capabilities far beyond what is possible in Web Apps and PWAs.

It works as a web service. Zip your project, upload to VoltBuilder, and download executables for Android or iOS.

In designing VoltBuilder, we had the advantage of starting with a clean slate. We were able to simplify and speed up the workflow. We also kept it framework neutral: VoltBuilder does not use any other AppStudio products, nor does it restrict the use of other frameworks. There is nothing to install.

About Us

We started in 1993 at the introduction of the Newton to fill the need for easier to use development tools. Our first product, NS Basic/Newton, was a success. When the Newton was cancelled, we introduced NS Basic/Palm. It also did well, so we added NS Basic/CE.

In 2010, we realized that JavaScript on mobile devices was getting fast. Web pages in those days used a bit of JavaScript to augment the page: Could we flip things around and make JavaScript the core of web pages, driving the HTML and CSS? That resulted in AppStudio, targeting iOS and Android. It now has thousands of users in over 80 countries. More than 2 million students have learned how to program using it.

The same core group of developers has been at work on AppStudio for many years. We enjoy what we’re doing - we’ve built a loyal base of customers by treating them fairly and providing great support.
