Use customized or make from this one – Moodle Mobile Review

Apps is too generic to use as-is. Being 100% open source best route is drag into your IDE and modify to your (company, product, school) needs as we all do with Moodle CMS/LMS. That’s it’s intended purpose. There is no shortage of Moodle coders for $15-20 USD per hour. For $400 to $1000 you’ll have great app specific to “your” needs.
