Any suggestions for paid one time purchase apps on the Google play store?

    1. Password Safe Pro
    2. My Expenses
    3. FL Studio, formerly Fruity Loops (also: Desktop)
    4. Threema
    5. Through the Ages (boardgame adaption)

    Otherwise, I usually prefer free open source solutions (FDroid), but I regularly donate to keep the projects alive. 1 and 2 are small dev studios that I am happy to support.
