Verdict
The clearest difference is in-app purchases: i Sound Level Meter at none against SonoMeter's 4. i Sound Level Meter also leads on update cadence (every 2 months vs every 8 months) and iOS requirement (13.0 vs 16). SonoMeter's advantage is ads (none vs shown). On price and device support there is nothing between them.
