How well do phone snoring apps agree with a sleep lab?

Single study · validation ■■□□ low evidence: one centre, small selected sample

Who: 60 people at one sleep centre in Taiwan; 52 were analysed (43 men, 9 women). 31 had severe, 10 moderate and 9 mild sleep apnea; 2 were normal. These were lab patients, not the general population.
What they did: SnoreLab, Anti Snore Solution and Sleep Cycle ran on three phones of the same model during the same night as polysomnography.
What they found: All three apps' recording time and snore counts correlated significantly with the lab; Anti Snore Solution showed good agreement on snore counts. Correlations between app measures and apnea severity (log AHI) ranged from rs = 0.34 to 0.38, and Sleep Cycle's sleep quality score correlated inversely (rs = -0.49). The authors suggest some measures may help anticipate moderate to severe apnea.
Limits: As the authors note: one centre and a small sample; very few mild or healthy participants; only correlation and Bland-Altman analysis, no event by event comparison; other phones' microphones and newer app versions may change results. No conflicts of interest reported.

What does this mean for you?

A snoring app can help you see when and how much you snore. If you suspect sleep apnea, the decision belongs to the sleep test a doctor orders, not to an app. This is not advice.
