Preffect reads what your body's already telling you and turns it into one clear action — the single highest-leverage thing for your health today. No guilt. No overwhelm. Just clarity.
Free to start · Use it solo, or sync with Apple Watch & Apple Health
Your Daily Focus changes every day because your data does. Had restless sleep? It suggests a mindful walk. Building energy? It helps you use the momentum. Not a program — just one thing that makes sense today.
You're building energy-supporting routines, and Boost Energy Levels is a great fit for one simple lunch upgrade.
Top your lunch with berries and a handful of nuts today. You'll feel a steadier lift through the afternoon.
Use Preffect on its own, or connect Apple Watch, Apple Health, and your calendar for sharper recommendations. Flo and Clue integrations are coming soon, with more on the way.
The app is fully usable on its own. If you wear an Apple Watch, use Apple Health, or want calendar context, sync them in seconds for richer signals.
Raw numbers aren't helpful on their own. Preffect synthesizes your signals into context — what's changed, what it means, and what to do about it today.
Your Daily Focus — the single thing that makes the biggest difference for your health today. Explained clearly enough that you know exactly why.
Most apps add complexity. We reduce it. You shouldn't need a second job to take care of yourself.
Success isn't doing more. It's choosing well. One good decision today compounds over months — without asking more of you tomorrow.
Missed a day? Your data kept flowing. When you come back, Preffect picks up exactly where you left off. No catching up required.
We don't just tell you what to do — we explain why. Understanding builds trust. Trust builds habits that actually last.
Day 1, you get direction. Day 7, recognition. Day 14, real insight. The longer you use it, the sharper it gets — but the effort stays the same.
Every feature exists to answer one question: what actually matters today?
Based on your sleep, activity, nutrition, and how your week has been going. It changes every day because you do. Not a program — just one thing that makes sense today.
Log meals and workouts in seconds with your camera or your voice. No counting, no searching, no manual entry — even when you're not wearing anything.
Sleep, activity, emotional wellness, and nutrition — each with plain-language breakdowns you'll actually understand.
Apple Watch, Apple Health, and calendar work today. Flo and Clue are coming soon, with more integrations on the way.
Over time, Preffect learns your patterns and rhythms. Recommendations get sharper. The experience stays the same: one thing, every morning.
Everything you need to know about getting started with Preffect.
