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. EVERYTHING ELSE YOU NEED • Fasting timer with Live Activity on your lock screen • Streaks, badges and 30-day challenges • Daily 1-minute micro-lessons that explain the why behind every habit • Journal with on-device dictation and AI prompts • Weekly reports, trends and health insights • Home Screen widgets and an Apple Watch app • Partner accountability — share your protocol with someone who keeps you honest • iCloud sync and full privacy: your health data stays on your device ZUVA PRO The first protocol week is free, forever.

Verdict
The clearest difference is device support: Zuva at 2 against BioFlow's —. On price, in-app purchases and iOS requirement there is nothing between them.
