About Hassan Aldridge-Yamaguchi

Hassan runs the data desk. Every accuracy claim on this site is sourced through him — either as a direct citation to the DAI 2026 Six-App Validation Study, or as one of our internal benchmark runs against the 240-meal battery he maintains. His bylines own the most-accurate-tracker coverage, MAPE-explainer pieces, and any head-to-head comparison whose decisive criterion is an accuracy number. He is the team member who will tell you to slow down and check the confidence interval before publishing a “winner.”

Credentials in detail

• MS, Statistics — Cornell University (2017)
• BS, Mathematics — UCLA (2014)
• American Statistical Association member
• Pre-Lab career: four years quantitative analyst at a Pacific-coast academic medical center, two years as a consulting biostatistician for a digital-health startup

Editorial focus

Hassan owns: accuracy methodology, MAPE protocol, internal benchmark runs, all data-driven pieces (most-accurate roundup, MAPE explainer, accuracy-bound head-to-heads). He gates every accuracy number that appears anywhere on the site, including in keystone pieces written by Edith.

Conflicts of interest

Hassan holds no equity in any reviewed app. He has no consulting relationships with any of the app makers in our review universe and has not had any in the prior three years. He does not run affiliate accounts. He does occasionally accept complimentary premium accounts for sustained testing, disclosed individually. See our no-affiliate disclosure for the publication-level statement.
