Key Takeaway
The Phoenix mobile app is in beta on iOS and Android for APOE4 carriers. Two core features: 30-second daily check-ins that surface correlations across sleep, HRV, food, and supplements (example pattern: 'late eating drops HRV by 20 percent'), and a unified health hub connecting Apple Health and Google Health Connect to aggregate Oura, Whoop, Garmin, Apple Watch data with bloodwork and daily habits.
Definition
A 30-second daily self-report of how you feel and what you did, designed to surface correlations across health factors over time.
Daily check-ins generate longitudinal data points that single snapshots cannot. Rated dimensions typically include sleep quality, cognitive clarity, mood, and energy, combined with tags for supplements, food timing, alcohol, exercise, and interventions. Over weeks and months, this data reveals personal correlations that would be invisible in any single day. For APOE4 carriers tracking multiple interventions simultaneously, daily check-ins are the primary way to identify what is actually moving the needle versus what is just expensive placebo.
