What's New
Changelog
Protocol ships fast. Here's everything that's been added, improved, and integrated. Updated weekly.
March 2026
Protocol Fit
Early access to Protocol Fit, the companion app for strength tracking, is now available. Log workouts, track personal records, and get progression guidance that connects to your recovery data in Protocol.
Premium subscription
Protocol Premium is now available. Upgrade to unlock the AI coach, daily and weekly email briefs, coaching insights, and trend analysis. Beta pricing available for early members.
New Coach experience
The coach now has a dedicated chat tab with continuous conversation — no more starting fresh each time. Responses render with full formatting. A separate Reports tab holds your structured coaching analysis. Hit Enter to send on desktop.
New calculators
Four new tools are live at /calculators: Caffeine Window Calculator, Sleep Cycle Calculator, Zone 2 Heart Rate Calculator, and Macro Calculator with full TDEE breakdown.
Meal log management in Goals
You can now view, edit, delete, and manually add meals in the Goals > Nutrition section. Meals logged via the AI coach or manually added are all editable in one place.
Protocol Glossary expansion
Five new metabolism and nutrition terms added to the glossary, with practical food examples, range cards, and links to relevant learn articles.
Deeper coach memory across conversations
The AI coach now draws on your recent conversation history across sessions, not just the current chat thread. It remembers context, recognizes recurring themes, and builds on what it already knows about your patterns over time.
Smarter multi-device handling
Protocol now respects your device preferences per metric. If you use WHOOP for recovery and Oura for sleep, Protocol pulls from the right source for each one, and updates instantly when you change your preference without requiring a re-sync.
Daily and weekly email enhancements
The daily brief email is rebuilt from scratch: a 2-3 sentence AI narrative synthesis leads the email, followed by a split scorecard (sleep and recovery from last night, activity from yesterday) and a single pattern-focused coaching block. Duplicate send protection is in place. Weekly emails now include a goals nudge alongside your trend comparison.
Coach-first dashboard
The dashboard no longer just shows your data, it tells you what it means. The Coached Today tab now leads with a Daily Brief card: a two-sentence synthesis of your day with a direct action, sitting above your metrics so the coaching layer is impossible to miss.
Metric Insights
Every metric row on the dashboard now surfaces an AI-generated insight when your data is worth flagging, including low recovery trends, HRV dips, and missed protein targets. Tap the ✦ pill to expand the full story: what the pattern means, why it matters, and what to do about it.
Overhauled Coach report
The Reports tab is redesigned as a unified coaching document. An overall summary leads the page, each section has a focused Ask CTA, and the layout matches the visual language of the rest of the coach experience.
Welcome email for new users
Everyone who signs up now gets a welcome email from Evan — what Protocol is, what to set up first, and an invitation to reply with questions. It is the first touchpoint outside the app.
Learn library expanded
New Learn pages are live covering key health topics, from how to read your wearable data to the science behind sleep architecture and recovery. The glossary is growing weekly with terms that connect to the data Protocol already tracks for you.
Protocol frameworks now live
The full Protocol library is here: Sleep, HRV, Recovery, Stress and Cortisol, Protein, Strength, Zone 2 and Cardio, Fat Loss, Whole Foods, Hydration, Daily Movement, Lab Work and Biomarkers, Temperature, and the Long Game. Each one is a deep science-backed framework built to actually change how you train and recover.
Protocol Glossary
New Glossary section with searchable health and fitness terms. HRV, Slow-Wave Sleep, VO2 Max, Zone 2, and Cortisol Awakening Response are live with full definitions, mechanisms, and what your wearable is actually measuring. More terms every week.
AI coach remembers your past conversations
The coach chat is now persistent. Your conversation history is saved so you can pick up where you left off, revisit past insights, and build on what the coach already knows about your patterns.
Weekly email summary
Get a weekly health brief in your inbox every Monday — week-over-week comparisons of sleep, HRV, steps, workouts, and protein, with AI-generated insights on what changed and why.
Light, dark, and system theme support
Protocol now fully supports light mode, dark mode, and a system-adaptive setting that follows your OS preference. Switch anytime from settings — it updates instantly across the whole app.
Trends page
A new Trends tab shows how your health metrics are moving over time. Sleep score, HRV, body weight, resting HR, protein, steps, and more — each with a 7- and 30-day view and an AI-generated insight to help you read the patterns.
Faster performance throughout the app
Coach cards, trends insights, and sync results now load faster and without layout shifts. Data is cached smarter so navigating between tabs feels snappy.
Hydration tracking with custom logging
Track your daily water intake directly in Protocol. Log oz in any increment, set a daily goal, and watch your progress update in real time. Delete individual entries if you make a mistake.
Daily email summary
Get a daily brief delivered to your inbox each morning — your sleep score, recovery, key metrics, and an AI coaching insight. Turn it on from notification preferences in settings.
Expandable metric cards on the dashboard
Each metric row in the daily scorecard now expands to show deeper detail — sleep stage breakdown, HRV history, protein progress, body composition, and more. Tap any row to dig in.
WHOOP integration
WHOOP users can now connect directly via OAuth. Protocol syncs strain, recovery, and sleep data nightly — all visible in your daily scorecard alongside Oura and Apple Health.
Oura Ring integration
Direct Oura OAuth connection is live. Sleep score, readiness, HRV, resting heart rate, and body temperature deviation all sync into Protocol automatically.
February 2026

Protocol's AI coach is live. Ask it anything — what your sleep trend means, whether to train hard today, how close you are to your protein goal. It has full context on your data, not just the last message.
