I think apps and other types of transmedia are hugely important for any project.
Here in MN coders and designers charge around $75 - 100 / hour to create something custom. Depending on what info you are trying to get across, there are different easy ways to get your app through on a low budget. Here is some info, pls keep in mind I'm a producer, not an app developer, so there are more options out there than what I'm listing:
- create a web app (a glorified webpage that works on mobile phones), these tend to be cheaper bcs more people know how to do them. Down side is that they require a WIFI or Internet connection to work.
- non-custom. There are a lot of companies starting up that are really good at producing a specific type of app. You upload your info / content into their template, and bam! You have an app. Their services are more subscription based (one i'm looking at is $200 / month) and they will take care of submitting it to iTunes and Android market. Downside is that you'll be working off a template. Any customization will take additional $$$.
- Mobile Website. Just like a website but it will conform to the small screens of mobile phones. There are a lot of DIY resources for this, and the costs are minimal... but you will still need to buy a URL, and host it. If you are already building a site for your film, why not include a mobile ready site too?...
This was helpful. Have you used any transmedia for projects? If so, do you have a link?
