FretBuzz Progressions is an application for learning and practicing common jazz chord progressions on guitar. It shows chord diagrams for ii V I, I vi ii V and Blues progressions. Blues progressions cover basic blues with two fives and turnarounds and advances to Charle Parker's Blues for Alice. The chords/diagrams listed start with basic chords/diagrams and then advance to chords/diagrams with extensions and alterations (when possible). All chords/diagrams are connected with smooth voice leading. The chord diagrams used are the common chord shapes used in jazz guitar; - Shells - Drop 3 Chords - Drop 2 Chords - Drop 2 & 4 and Drop 2 Chords. The application can play the progression and it's variation you choose along with a metronome. You can set the speed of the metronome and follow along as the playing chord/diagram is highlighted. You can tap on the chord name to hear its sound. Tapping on a chord note will play only that particular note. You can adjust the size of the chord diagrams for your device. There is also a left handed option in the settings. You can think of this application as volume II of my "FretBuzz Chords" app.

Verdict
The clearest difference is price: E at Free against FretBuzz Progressions's $4.99. E also leads on update cadence (every 3 months vs every 31 months). FretBuzz Progressions's advantage is in-app purchases (none vs 1) and iOS requirement (12 vs 17.6). On ads and device support there is nothing between them.
