MuscleBuddy Open Beta Is Live

Today we're opening the doors. MuscleBuddy is now in open beta — free to everyone, no credit card, no waitlist. If you train and track, it's built for you, and you can start in the next two minutes at musclebuddy.net.

The problem with most fitness apps

Almost every training app hands you a plan and then never touches it again. You do the work, you log the sets, and the app just… sits there. Real coaching doesn't work that way. A good coach watches what's actually happening — the lifts that stalled, the weigh-ins drifting off target — and adjusts the plan around it.

That's the gap MuscleBuddy was built to close.

What MuscleBuddy actually does

MuscleBuddy reads your real data and reacts to it:

• Training that progresses itself. Log your sets and it loads the right weight for today. Hit your targets consistently and it advances you automatically; stall out and it adapts — across five progression methods, with periodization and automatic deloads built in.
• Nutrition that adapts to you. Set a goal and your macro targets adjust to your weekly weigh-ins — through bulks, cuts, carb cycling, and contest prep — against a database of 7,000+ foods.
• Analytics that go deep. Volume, frequency, and strength trends broken down by individual muscle group, with body-composition history and symmetry tracking.
• Progress worth chasing. Climb per-muscle ranks from Wood to Legend, top the leaderboards, and go head-to-head in challenges — every tier earned from real training data, not participation.

And it explains why it made every change, because a black box that just says "trust me" isn't coaching either.

Free forever — and a Pro tier when you want more

The core of MuscleBuddy is free, permanently: workout logging with auto-progression, nutrition tracking and macros, weigh-in tracking, progress charts, the social feed, and full offline logging. No credit card to start.

Pro ($9.99/month) adds the deep-end tools: AI coaching chat, meal planning and recipes, carb cycling and refeeds, health and bloodwork tracking, the per-muscle rank diagram, leaderboards and challenges, contest-prep tools, and a supplement-interaction checker.

The founding-member challenge

To kick off the beta, we're running a challenge with real stakes. Log a qualifying day — a daily check-in plus at least one logged meal — on 20 of your first 30 days, and if you're one of the first 100 people to finish, you get a full year of Pro, on us.

Your personal 30-day clock starts the day you join, so joining early only helps. It's the cheapest year of Pro you'll ever earn — you just have to show up and log.

Train anywhere

MuscleBuddy installs as a progressive web app straight from your browser — no app store, no download queue. It works fully offline, so you can log every set and meal with no signal in the basement of your gym, and everything syncs the moment you reconnect.

We're building this in the open, and beta is exactly when your feedback shapes the product most. Try it, push on it, and tell us what's missing — we're listening.
