Longevity tracker
Longevity isn't one thing — it's the compound effect of fasting, exercise, sleep, cold exposure, supplements, and stress management, done consistently. OutLast tracks ALL of them in one place so you can see the full picture of your healthspan protocol.

The problem
Your fasting app doesn’t talk to your sleep tracker, your workout log, or your supplement list — you have no unified view of your longevity protocol
There’s no single metric for longevity, so you need to track the STACK — the 5 pillars of exercise, nutrition, sleep, stress management, and connection
Missing one day feels invisible, but longevity is compounding — small gaps in consistency add up to years of lost healthspan
OutLast puts your entire longevity protocol in one daily log — so you can see the compound effect of doing the right things consistently
How it works
Fasting windows, Zone 2 cardio, sleep, cold plunge, supplements, sauna — log each one with a quick tap. Your entire longevity protocol is captured in under a minute.
Create custom goals like "Zone 2 cardio 3x/week," "8 hours sleep," "daily cold plunge," or "16:8 fasting." OutLast auto-checks each goal as you log entries throughout the day.
Your streak and score show the compound effect of showing up every day. Over weeks and months, see the pattern — the days you do the full stack are the days you feel your best.
What you get
Exercise, nutrition, sleep, stress management, and connection — track every pillar of longevity in a single daily log. No more scattering your healthspan data across 5 different apps.
One streak counter for your entire longevity protocol. See your current streak, longest streak, and daily score — proof that you're compounding the habits that add years to your life.
Set targets like "Zone 2 · 3x/week," "cold plunge daily," "8h sleep," or "16:8 fasting window." OutLast automatically tracks progress and checks off goals as you log matching entries.
Scroll back through weeks and months of daily logs. Spot the patterns — which combination of habits gives you peak energy, best sleep, and the highest consistency score.
The science
What people say
“I follow a Peter Attia-inspired protocol — Zone 2, strength training, sleep optimization, fasting. OutLast is the only app where I can log all of it and actually see my consistency over time.”
“Longevity is boring. It’s doing the same 6 things every single day. OutLast makes that boring consistency visible and rewarding. My 90-day streak is the proof I needed that I’m on the right track.”
“I was using a fasting app, a sleep tracker, and a notes app for supplements. Now everything is in one place. I can finally see whether I’m actually doing the full stack or just the easy parts.”
