Built under
load.
Train like it’s your job. Eat like it matters. ReBarOS is the one app that replaces your workout tracker, macro logger, and personal coach — built for anyone serious about getting stronger.
Concrete cracks under pressure.
Rebar doesn’t.
Rebar is the steel skeleton hidden inside concrete — the tension it can’t crack, the strength that carries the load. ReBarOS is that skeleton for your training. The structure underneath every rep, every meal, every week — turning raw effort into a stronger, unbreakable you.
Rebuild yourself. Be the rebar.
Stop juggling five different apps.
ReBarOS combines everything a serious lifter uses — and adapts to you, not the other way around. Whether you’re training your first year or your twenty-fifth.
AI Progressive Overload Coach
Every set you log gets analyzed. When you're ready to add weight, the coach tells you — in plain English. When you're not, it holds you back. No more guessing.
Rest timers that keep up with you
90 seconds between sets. 3 minutes between exercises. Auto-starts the second you check off a set — with haptics that tell you when to lift again.
Macros made visual
Rings, not spreadsheets. Log by search, barcode, or AI photo.
Auto PR detection
Beat a lift? We celebrate. Every rep max, tracked forever.
Injury-aware training
Flag a joint. The AI reroutes your program around it — instantly.
Snap a photo. Get macros.
Vision AI identifies your meal, estimates portions in US ounces, and logs it — in under two seconds. No more typing in "chicken breast, grilled, 6 oz."
Share the wins. Skip the noise.
A transformation Gallery that's actually curated — AI moderation keeps it clean, community reporting keeps it real. Fitness-focused, always.

The short answers.
Can I use ReBarOS for free?
Yes — the core workout tracker, macro logger with search + barcode, and basic analytics are free. The AI coach, photo meal scanning, and unlimited program generation live behind the $24.99/mo Premium tier. Every new account gets 3 days of Premium free.
What makes the AI actually different?
Most apps slap "AI" on a generic template. ReBarOS reads your actual logged sets, your goal, your available equipment, and any joints you've flagged as injured — and rewrites your program accordingly. When you PR, it notices. When you plateau, it changes tactic.
Will my data stay private?
Yes. Zero ads, zero data sales. Photos you snap for meal logging are analyzed and discarded (not stored). Gallery posts are opt-in only. You can delete your entire account, including all training and meal history, from inside the app.
US or metric units?
ReBarOS is US customary by design — pounds, inches, ounces. Built for the American lifter who's tired of every fitness app defaulting to kilograms.
What happens after the 3-day trial?
You'll be charged $24.99/month via your App Store or Google Play account. You can cancel any time inside the app or your store settings. Cancel before day 3 and you're never charged. No renewal traps.
Stop tracking. Start training.
You already know what to do. ReBarOS just gets out of your way.
