Penultimate 5.0 version in Penultimate Posted November 14, 2013 I bought the Adonit pen and tried with penultimate and other inking apps. Although the look and feel if the Adonit is the best I've tried to date, it was just too laggy for me. Penultimate is unusable for me. I had been using Notes + and Notability. Back to the trusty Livescribe Wifi.
