Verdict
The clearest difference is price: Sound Meter at Free against RTMP直播助手's $3.99. Sound Meter also leads on iOS requirement (13.0 vs 16.0). RTMP直播助手's advantage is ads (none vs shown) and update cadence (every 3 days vs every 8 days). On in-app purchases and device support there is nothing between them.
