The major update introduced a rewritten engine and new chord analysis tools, yet the rating average remains stagnant at 4.0 stars. While the app maintains its utility as a physical book replacement, the introduction of technical inaccuracies in chord data offsets gains. The net impact is neutral due to insufficient review volume and polarized user feedback.
