Verdict
The clearest difference is price: CHM+ at Free against CHMate+'s $9.99. CHM+ also leads on review sentiment (83% vs 61%) and iOS requirement (15.0 vs 18.0). CHMate+'s advantage is rating (3.8 vs 3.0) and in-app purchases (none vs 1). On update cadence and device support there is nothing between them.
