Mahara is an open source ePortfolio system designed for social learning. An ePortfolio is a system in which learners can record evidence of their learning, e.g. essays, artwork, certificates, reflections or other such things they produce that can be stored digitally.
Mahara Mobile allows you to collect your evidence on your mobile device and also when you are offline. You can then upload it to Mahara and put into your portfolios.
In order to push content to Mahara from Mahara Mobile, you require an account on a Mahara site that allows mobile uploads. Typically, the institution that you are affiliated with will make a Mahara instance available to you to use if you are working with portfolios.
Mahara Mobile is an open source project. To contribute or report bugs, see https://github.com/MaharaProject/mahara-mobile
