There are several DNA analysis apps. But most of them are subscription-based. DNADynamo is a static license app. It means that once you purchase a license, you get full support for these licenses, including future updates. We have five licenses in my lab, and I can easily transfer the licence on the computer of the finished student to the one who has just started. The interface is improving with every update, and I can say I love the app!
