Verdict
The clearest difference is in-app purchases: SleepNoize at none against PeakflowLogger's 1. SleepNoize also leads on ads (none vs shown). PeakflowLogger's advantage is update cadence (weekly vs every 6 weeks). On price, review sentiment, device support and iOS requirement there is nothing between them.
