<p>We compared the b (amplitude of phase II)-to-a (that of phase I) ratio of acceleration-photoplethysmogram (APPG) derived from the photoplethysmogram (PPG) device as a reference with the b/a ratio of APPG derived from smartphone (iPhone 6). In 20 participants (32.1 ± 12.5 S.D. years), simultaneous measurements of near-infrared PPG, green light PPG, and iPhone 6 PPG from the index fingers were made. The results showed that the b/a ratio of APPG derived from the green light PPG device was significantly related to b/a ratio of APPG derived from the iPhone 6 (<i>r</i> = 0.789). In addition, the mean difference in <i>Bland-Altman plots</i> between these b/a ratios was -0.012, and the limit of agreement (2 S.D.) was 0.178. The significant differences were not observed between the b/a ratios of APPGs in each wavelength. In conclusion, these findings suggest that iPhone 6 PPG might be valid measure for estimation of finger-vascular aging.</p>
