I upgraded Devon Think as a Christmas present for myself. There is no problem with this version, but I upgraded it because I want it to be improved in the future. Looking at the account history of DEVON Think, I bought the Personal Version in 2012 and made it the Pro Version the following year. I remember buying the app at a bundle sale rather than buying it directly. I hope it will continue to grow in the future.
