  • •Each habit links to peer-reviewed research articles, not just claims.
  • •Custom habits alongside the core six lets users extend beyond longevity.
Weaknesses
  • •Habit tracker category is saturated — Streaks, Loop, and Habitica already exist.

Post Description

I made it for me, nothing fancy, but feel free to use it as well.

It's free, no account needed (no server, all data stays on your phone), no tracking, open sourced (https://github.com/bdav24/illll).

It's a tracker for 6 longevity habits backed by research:

1. Sleep — brain clears toxic waste during deep sleep, <7h raises mortality 13%

2. Exercise — 11 min/day of walking cuts premature death risk 23% (Br J Sports Med, 2023)

3. Healthy eating — cuts depression risk 33% (SMILES trial), cardiovascular disease 30% (NEJM, 2018)

4. Structured breathing — 5 min/day, lowers cortisol, raises HRV (Stanford, 2023)

5. Morning sunlight — 10-30 min, sets circadian clock, boosts serotonin (JAMA Psychiatry, 2016)

6. Gratitude — writing 3 things daily, measurable neural changes lasting months

But you can also set custom goals and add your own habits.

HabitStreak – Habit tracker with giftable streak tokens

The product doubles down on the Seinfeld "don't break the chain" idea with sensible, social-forward features: 30-day heatmaps, unique public share pages, streak counters, reminders and a one-time lifetime purchase option. The landing page sells the behavioral pitch well, but the field is crowded and the promised "giftable streak tokens" concept (in the title) isn't clearly explained on the page — useful for individuals, not a breakthrough.
