The longevity industry sells $200/month supplements and 4am cold-plunge routines. The actual research points to 6 simple daily habits — sleep, exercise, breathing, morning light, healthy food, gratitude — that cost nothing and take seconds to track. ILLLL is a private, source-available app that helps you do them.
Hey Hunters 👋
I'm David, maker of ILLLL. I built this because the longevity space has gone insane — $200/month supplement stacks, $2M/year Bryan Johnson protocols, 14-step morning routines. Meanwhile, the peer-reviewed research keeps pointing to the same boring 6 things humans have always done:
😴 Sleep
🏃 Exercise
🫁 Structured breathing
☀️ Morning sunlight
🥗 Healthy food
🙏 Gratitude
Adapted to you: your goal may be to walk 10 minutes daily or hit the gym, your call.
No supplements. No subscription. ~30 seconds a day to log.
What I cared about while building it:
🆓 Actually free — No account, no paywall, no in-app purchases. Ever.
🔒 Actually private — All data stays on your phone. Zero network calls. No analytics, no SDKs, no telemetry.
📚 Actually science-backed — Each habit links to the studies (JAMA, NEJM, Science, BMJ, Cell Reports Medicine — 18 papers total).
🎨 Beautiful & calm — No streaks-shaming, no notifications guilt-tripping you. Just a quiet daily check-in.
👀 Source on GitHub — audit every line.
I built it for myself first. Sharing in case it's useful for you too.
Would love feedback!
