1. App Machine –
Slick and efficient.
Templates galore, easy to build, the support team will hold your hand (and wipe your tears if you pay for extra support options) all the way through building and publishing.
You build apps directly in the browser and you can download a viewer app on your iPhone/iPad to preview as you work, live. It features an easy to understand interface – you add content by adding “building blocks” that contain text, video, location maps, calendar of events, contacts, social media feeds, etc. You can add more advanced features if you choose one of the more expensive plans.
2. Coverpage –
You can design and rock your own content within a neatly structured navigation shell. No templates here. Download free Coverage Publisher to your computer and start building your app. First, create your app pages layout in applications like Adobe InDesign (or really any other app that allows you to build a jpg, png, or pdf). Then bring it into Coverage Publisher and add as many interactive elements as you want.
The website has all the help files you may need to get started and its team responds to help requests almost immediately. They make it easy to add app functionalities if you write code (or if you don’t code, you could find what you need in one of the online code repositories, (such as GitHub: https://github.com) and incorporate it into your app.
3. GameSalad –
Build your own games.
Another drag-and-drop builder. Publishing options depend on the plan you purchase and include iOS, Android, Kindle, Nook and Windows and Mac desktops. Provides choices of content such as graphics, templates, audio, etc.
GameSalad pays particular attention to using games in education. You can find a list of resources for educators here: http://gamesalad.com/education/resources-for-education and read what other educators say about incorporating game apps in their teaching: http://gamesalad.com/education/stories-from-teachers
4. AppsBar –
Yes, this builder is absolutely, completely, hundred percent free, no payment plans whatsoever, even if you ask for it. You can create HTML5 apps and publish to a free apps marketplace Appcatch: http://www.appcatch.com/
You could later publish your app to Google Play or Apple App Store, but on your own, so it probably won’t be as easy (for most users) as when you sign up for one of the plans with other builders.
5. Appy Pie –
Apps and games, plus some cool features.
Offers both apps and games publishing and provides a good variety of interactive features like Live Video Streaming with Ustream, or Geotargeted Notifications, etc.). On the website, you can take a look at some of the examples of educational and augmented reality apps recently created with Appy Pie.
