Run self-experiments. Measure what works. Keep only what earns its place.
You've tried before. It didn't hold. Not the cold showers. Not the 5am starts. Not the supplements or the streaks. Something worked for a week — then it didn't. That's not a willpower problem. It's a measurement problem. Cold showers worked for someone on a podcast. Fasting worked for someone on Reddit. The advice is real. The results are someone else's. You are not a case study. You are the experiment. Protocol is a lab for running structured experiments on yourself — one at a time, time-boxed, and judged on your own data. It is deliberately NOT a habit tracker. There are no guilt streaks, no endless checkboxes, no badges. There is a question — "does this actually work for me?" — and a clear answer at the end. HOW IT WORKS 1. PICK — Choose a protocol from the curated library, or build your own. No Added Sugar. Cold Showers. Phone-Free Mornings. Deep Work. Lights Out 22:00. Sleep Optimization. And more — each 14 to 30 days, with one clear daily task. 2. MEASURE — A one-minute daily check-in. Mark the protocol done, log a few metrics that matter — energy, mood, sleep, focus, cravings — and an optional note. Day 0 captures your baseline so every change is measured against where you actually started. 3. TRACK — See adherence, metric trends, and the delta from your baseline on clean, honest charts. No vanity numbers. Just signal. 4. DECIDE — At the end you make an explicit verdict: keep it, drop it, or abandon it. Kept changes move to your permanent set. Over time you build a personal record of what genuinely works — for you, not for a stranger online. WHY PROTOCOL IS DIFFERENT - n=1. The only sample size that matters is you. - One experiment at a time. Focus beats a dashboard full of half-kept habits. - Baseline-aware. Progress is measured against your real starting point. - A verdict, not a streak. Every experiment ends in a decision, not in guilt. - Offline-first. Your log lives on your device. No account required to start. - Private by design. Optional encrypted cloud backup — only when you ask for it. WHAT YOU CAN TRACK Physiology, focus, and discipline protocols covering sleep, sugar, alcohol, movement, screen time, deep work, cold exposure, and personal reliability — each with metrics chosen to actually answer the question. FREE & PRO Protocol is free to use: run one active experiment and access the core protocol library. Protocol Pro unlocks unlimited active experiments, the expanded protocol library, and full analytics. - Monthly and annual plans available - 7-day free trial - Cancel anytime in Google Play No ads. Ever. No selling your data. Ever. Stop following someone else's protocol. Run your own. Pick one experiment. Start today. The data will show you the rest.
