I think threema is a great product and at the same time a core reason why they haven't grown bigger yet is because they don't experiment enough with pricing models. Successful apps I know offer some standard functionality for free, get users to use the app and then offer additional functionality that a certain amount of people will buy after they have fallen in love with the product. There is no chance competing with all the free messengers otherwise.
