Verdict
The clearest difference is in-app purchases: MechaSense at none against Decibel dB's 6. MechaSense also leads on rating (5.0 vs 4.7). Decibel dB's advantage is ratings volume (676 vs 1) and iOS requirement (12.4 vs 15.1). On price, update cadence, ads and device support there is nothing between them.
