About this app

prtcl is a protocol tracker built for people who follow structured, evidence-based health programs.

If you follow longevity, nutrition, fitness, or biohacking protocols and track them in spreadsheets, Notion, or not at all, prtcl gives you a purpose-built tool to manage and measure your adherence.

HOW IT WORKS

Browse a curated marketplace of ready-made protocols across 12 categories including longevity, nutrition, sleep, cardiovascular health, skin health, recovery, and more. Adopt any protocol and it becomes your own editable copy. Toggle steps on or off, adjust targets, or add custom steps to match how you actually follow it.

Log your daily steps in under 60 seconds. Checkboxes, numeric inputs, and tally counters cover every step type. Your adherence score updates in real time as you log.

WEIGHTED ADHERENCE SCORING

Unlike simple habit trackers, prtcl weights each step by importance. A high-priority step like sleep or Zone 2 cardio counts more toward your score than a low-priority one. Your adherence percentage reflects how well you're executing what matters most.

Track your score across three timeframes: today, 7-day rolling average, and 30-day rolling average. See which steps are strong and which need work.

PER-PROTOCOL INSIGHTS

Each active protocol gets its own insights dashboard with:
- Adherence ring with 7-day trend
- Strong areas and needs-work breakdown
- Calendar view showing logged days
- Trend chart with 7D and 30D toggle

CREATE YOUR OWN

Build fully custom protocols from scratch. Name your steps, set types (yes/no, measure, or tally), choose frequency (daily, weekly, or cyclical), pick scheduled days, and assign weights. Track anything from supplement stacks to training splits to morning routines.

BUILT FOR STRUCTURED PROGRAMS

prtcl treats a protocol as a structured program with weighted steps, measurable targets, and scheduling logic — not a list of unrelated habits. Schedule protocols with start dates and fixed durations, or run them open-ended. Mark rest days. Review completed protocols and archive them when you're done.
