Zuva: Longevity Habit Tracker

Biological Age & AI Coach

Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.

Build the habits science links to a longer life. Track your biological age, follow a guided protocol, and let your AI coach keep you consistent — one small win at a time. Most habit apps track everything. Zuva tracks what matters: the small daily habits that research links to a longer, healthier life. BUILT ON SCIENCE, NOT WILLPOWER Zuva guides you through a 4-week protocol that introduces a few habits at a time — morning sunlight, daily movement, an earlier last meal, a consistent sleep schedule. You unlock the next week by being consistent, not by rushing ahead. After week 4, the protocol adapts to you. YOUR BIOLOGICAL AGE, FRONT AND CENTER Zuva Age estimates your biological age from your habits and Apple Health data — and shows it improving as you stay consistent. Progress you can feel, and a number you can watch move. AN AI COACH THAT KNOWS YOUR DAY Ask anything about your protocol, your sleep, your streak. The coach answers with your real data in front of it — and checks in every week with what worked and what to fix. HABITS THAT VERIFY THEMSELVES Connect Apple Health and Zuva automatically confirms your steps, workouts, sleep and mindful minutes. Less tapping, more living. WIND DOWN, NOT DOOMSCROLL Evening wind-down mode and app blocking help you protect your sleep from your phone. Your screen time drops; your sleep improves.
