## Description

Protocol is the all-in-one for running your fitness protocol: habits, nutrition, and training. Lift. Eat. Track. Repeat.

Built for people with a goal. The app's job is to remove friction between intent and execution - fast logging, clear feedback, no noise.

LIFT
• Log sets with weight and reps (lbs or kg, per exercise)
• 100+ built-in exercises, or create your own
• Supports bodyweight and assisted (negative-weight) movements
• See your last attempt and personal record so you always know what to beat
• Templates for repeat sessions
• Per-exercise analytics and trends

EAT
• Log meals from a large food database
• Scan barcodes to add foods quickly
• Track calories and macros by day
• Backed by Open Food Facts and USDA data

HABITS & BIOMETRICS
• Daily habits, tracked like a protocol
• Body-weight logging with trends
• Home dashboard shows all three pillars at a glance

AI COACH (OPTIONAL, SUBSCRIPTION)
• Chat with an AI coach about training, nutrition, and recovery
• Powered by OpenAI; messages are sent to OpenAI to generate replies

PRIVATE BY DEFAULT
• Local-first: your data lives on your device (SQLite)
• Optional cloud sync, protected with row-level security
• No social features, no sharing, no feed - by intentional design
• We never sell your data
