I'm guessing Masso Link is written using Qt ? The size of the app window on my laptop is REALLY small such that the fonts and almost unreadable. The app *should* scale for retina-type displays by taking resolution into account, and in fact Qt can do this with the addition of a few lines of code. I have done this in the past and there is a Qt HOWTO online somewhere (do a DuckDuckGo or Google search for Qt and screen scaling).
