Protocol Zero is the first Active Sleep Improvement based on Research It’s a system that gives you a clear, personalized daily plan so you know exactly what to do to sleep better starting tonight. New: Protocol Zero now includes sleep sounds you can play at night, including white noise, brown noise, rain, and calming audio. Use them alongside your personalized nightly routine to unwind faster and fall asleep more easily. YOUR PERSONAL SLEEP COACH Unlike most apps that only track your sleep, Protocol Zero guides you through a daily schedule designed to reset your body clock and improve your sleep quality. Each day, you get specific actions that make a real difference: - Set a consistent wake time and get morning light exposure to reset your internal clock and help you feel alert during the day - Follow precise caffeine cutoffs so late-day coffee or tea never interferes with your deep sleep - Activate wind-down mode in the evening, which blocks distracting apps and helps your mind and body relax before bed - Practice science-backed techniques from Cognitive Behavioral Therapy for Insomnia (CBT-I), proven to help you fall asleep faster and stay asleep longer HOW IT WORKS Your body depends on a 24-hour internal clock to regulate sleep. Protocol Zero anchors your day around two key signals: when you wake up and when you get morning light. The app then schedules your caffeine, meals, exercise, and wind-down activities into optimal time windows. This structure helps you build habits that make you naturally tired at bedtime, so you fall asleep more easily and wake up refreshed. No more lying awake wondering what went wrong. No more generic sleep tips that never stick. Protocol Zero gives you a clear, automated plan that builds lasting habits for deep, restorative sleep. SIMPLE, SCIENCE-BACKED, AND ACTIONABLE Protocol Zero combines the most effective techniques from CBT-I the gold standard for sleep improvement with modern behavioral science. Research shows that tracking your habits and making targeted changes leads to real, lasting results. We make these techniques simple to follow, so you can start seeing improvements right away. WHO IT’S FOR Protocol Zero is designed for healthy adults who want to optimize their sleep. It is an educational tool, not a medical device, and is not intended to diagnose or treat sleep disorders. If you suspect you have insomnia, sleep apnea, or another medical condition, consult a physician. Stop guessing about your sleep.

Repwell is a workout tracker for people who actually lift. Log fast, progress on purpose, and see your training the way a data nerd wishes every app showed it — all while your data stays private on your device. LOG WITHOUT FRICTION • Start from a split, a multi-week program, or let Quick Workout draft a balanced session for the muscles you pick — big lifts first, sized to how much you want. • Tap to log weight and reps. The rest timer auto-starts and can prompt you on your lock screen when it's time for the next set. • "Beat last time" indicators show, set by set, whether you're moving forward. PROGRESS THAT MEANS SOMETHING • A progressive-overload engine suggests your next target — add weight, reps, or a set — based on your real history. • Deep stats: estimated 1RM charts with PRs marked, a rep-max board, lifetime volume, and per-lift progression rate. • Serious analytics: weekly sets per muscle vs. optimal volume landmarks (MEV/MAV/MRV), push/pull/legs balance, undertrained-muscle flags, a strength-standards breakdown with a DOTS score, and a consistency heatmap. GYM-AWARE, THE WAY REAL LIFTERS TRAIN • Set which gym you're at and Repwell adapts your workout to the equipment there, swapping in the best available lift when something's missing. • A new gym learns its equipment automatically from the lifts you log — no tedious setup. • Weights are remembered per gym for machines and cables (because the chest-press machine at your apartment isn't the one at your commercial gym), and globally for free weights. SHARE THE WIN • Turn any session into a clean, branded scorecard image and send it to a friend in a tap — or share as text. Nothing is uploaded; it uses your phone's share sheet. MADE TO LOOK GOOD • Polished light and dark themes, monospace numerals, muscle-color coding, and the kind of detail you'd expect from a top-tier app. PRIVATE BY DESIGN • No account. No cloud. No tracking. Everything lives on your device, and you can export your full history to CSV anytime. Works fully offline — perfect for the gym. Repwell is free right now — every feature unlocked.
