Form builders for mobile devices

We're going to build survey apps for rural development (in India) using cellphones, including some Nokia and Android devices. For building and capturing user info, we're looking at OpenXdata (which is open source J2ME solution) and exZact, (which works on iPhone/iPod Touch). We're also looking at ODK.

What tools/framework have other users used for the same ? Did you use cellphones or custom devices? What phones worked for you ? What are the pros and cons of each?

P.S : We're looking to develop for devices in the $100 category so that a big number of such dev开发者_Go百科ices can be deployed in the field cost effectively.

I found an open source solution (J2ME, FLASH and J2EE) from Nokia for

1. mobile
2. form creation
3. server side app

respectively.

If you need to use J2ME phones, I can highly recommend OpenXData. I worked on the project for many years, and have used it for many projects - some of which had nearly 1000 data collectors. I found the server very stable and never experienced any data loss.

If you wish to use Android phones, then I'd recommend ODK collect, which still has a very active community.

If you have more questions on OpenXData, you can reach out on our mailing list.
