BuildFire also allows you to add iCal so your audience knows what's coming. With this feature, I could see teachers using this as a class tool. You can also add social media to it as well. This allows for push notifications as well as social media updates.
Once you are ready to publish, there is a fee but in my classroom my student just wanted to get the feel for creating the app, so his app did not go live.
This semester, my students read a book of their choice. The only requirement was to create something meaningful from that reading. At the end of the novel of their choice they needed an end product. One of the students decided to pick "A Farewell To Arms" by Ernest Hemingway. As an English Teacher I was super impressed that this student chose such a classic.
He chose to create an app that gave the summary of this classic book. He also broke down the characters and gave analysis. There was even a tab to give back to soldiers because this classic story takes place during World War I. The student also provided a map of where the narrative took place as well as some background history. It was a really powerful tool and he inspired many other students to use Buildfire to create an app of their own!
This simple, student-driven project became something much bigger. It provided students with ownership and a way to create. Buildfire is easy to use and my students were empowered by being able to create with it. As I was writing this up, it hit me that this could also be a great resource for a teacher. We all do websites, but on a website we have to remind students to go to it. If we had an app, all their reminders, assignments, videos etc. would go to them without them needing to be reminded. Just another tool. :)
