So, the iOS version of Dexed MUST be open-source, MUST be published with the wholeness of the sources, MUST be provided with a copy of the license GPL v3, and MUST be free, the initial project having been released for free (only the additional services can be billed to the purchaser, so the $3.99 of this iOS edition seems a correct cost covering the usual expenses relative to the hosting on a server without any benefit). There may be fees demanded exclusively for the services related to the distribution, the cost of some services (the rental of servers, the annual cost of a domain, the rental of a repository) to the exclusion of any other fee or of any benefit. One of the points in the license GPL v3 is that a product (and all its derivatives) MUST be open-source, published with the wholeness of the source-code and released for free if the initial project is free. It means, within other things, that EVERY new project based on that project MUST be made with the same license GPL v3.

Dexed has been developed and is distributed on license GPL v3.
