MuscleBuddy is training, nutrition, health, and upkeep in one system: four modules that read each other, not four apps duct-taped together.

Most fitness apps hand you a plan and never touch it again. MuscleBuddy reads your real logged data and reacts: it progresses your training loads when you clear targets, adjusts your calorie and macro targets off your rolling weigh-in trend instead of a number you set once, and explains why every time. Every number you train by comes from a rule you can read, not a black-box AI guessing your targets. AI handles coaching conversation and analysis; it never sets the numbers.

TRAINING
Programs built around your goal, experience, and equipment, progressing your training load automatically as you log sets. Log a session in seconds, with your last numbers already in front of you.

NUTRITION
Food logging, recipes, and macro targets that move with your real progress. Targets adjust off your rolling weigh-in trend, not a number you picked once.

HEALTH
Bloodwork, vitals, recovery from real heart-rate variability and resting heart rate, sleep, and supplements, trended and explained, never diagnosed. Connects to Health Connect on Android, including Samsung Health.

UPKEEP
Medications, appointments, fasting windows, and the other maintenance cadences that run on clocks longer than a day, scheduled so a missed one never becomes a backlog.

COACHING AND COMMUNITY
Work with a coach who can see what you actually logged and adjust it, or train alongside other people: feed, groups, and leaderboards you opt into.

Subscription. Everything above is free. MuscleBuddy Pro ($9.99/mo) unlocks periodization, training phases and automated deloads, meal planning, AI coaching chat and advanced bloodwork markers, hormone and PCT protocols, and the compound library. Manage or cancel anytime from account settings.

Comprehensive enough for a competitive bodybuilder in prep. Approachable enough for someone who just wants to know what to do on Monday.

MuscleBuddy is not medical advice. Consult a qualified provider before changing any supplement, medication or hormone protocol. The compound and hormone modules require 18+ age verification.
