FitForge is a workout logger that's genuinely good and genuinely free: log your sets fast, rest on a haptic timer, and watch your lifts climb — with no ads, no account, and no nags. LOG SETS IN SECONDS Pick from a built-in library of about 60 common exercises across push, pull, legs, core, and cardio, then log sets, reps, and weight with a flow built for sweaty thumbs between sets. REST RIGHT A rest timer with haptic alerts keeps your breaks honest so your workout doesn't turn into a phone session. SEE YOURSELF GET STRONGER Full workout history plus per-exercise progress charts show your best set climbing over time. A bodyweight log tracks the bigger picture. START WITH A PLAN Built-in starter routines — Full Body, Upper/Lower, and Push/Pull/Legs — get you training today, plus a plate calculator so you never do barbell math mid-set again. PRIVATE AND COMPLETE Everything stays on your device: no account, no cloud, no ads, no tracking. FitForge is fitness logging for education and motivation, not medical advice. Want AI-generated plans and deep analytics? FitForge Pro is one tap away — but FitForge is complete on its own.

Most training apps, coaches, and influencers hand you a plan and hope it sticks. HybridO.S. is built differently. Your plan reads what your body is actually doing and rewrites itself accordingly. Set a new squat 1RM tonight and tomorrow's loads change. Sleep four hours, miss a session, or push past where the plan expected you to be? The plan responds. SHARPEN STRENGTHS. CLOSE GAPS. Your program is built around two ideas: doubling down on what makes you good, and quietly closing the gaps that hold you back. The work is yours. The reasoning is transparent. Nothing is generic. BUILT FROM PHYSIOLOGY, NOT TEMPLATES HybridO.S. is grounded in how your body adapts. Load, recovery, and readiness are treated as inputs to your program, not marketing buzzwords. The result is training that respects what you did yesterday and prepares you for what is next. THREE VIEWS, ONE PROGRAM Choose how much you want to see. - Simple: just today's work, no clutter. - Standard: today plus the week. - Detailed: every variable. The training is identical across all three. Display is preference, not a paywall. WHAT'S INSIDE - Adaptive periodization that responds to PRs, missed sessions, sleep, and soreness - True concurrent training: strength, conditioning, endurance, and sport-specific work in one plan - PR tracking, strength curves, and honest progress over time - Recovery tracking, readiness indicators, and load management - Optional Apple HealthKit and wearable sync (Whoop, Garmin, and others) for sleep, recovery, heart rate, training load, and everything else your wearable tracks - Body composition tracking, supplement logging, and guided breathwork. All opt-in. All private. FOR COACHES Manage your full roster from one screen. See everyone's readiness, compliance, and trends at a glance. Invite the people you coach with a private link. They get the same engine, you see the full picture. Comment on sessions, adjust on the fly, and review every variable per person without ever feeling like you are babysitting a spreadsheet. PRIVACY FIRST Your data is yours. Sensitive modules are opt-in, encrypted at rest, and never sold. No ads. No third-party data sharing. Cancel anytime in Settings. IMPORTANT: HybridO.S. is a training and wellness app. It does not provide medical advice, diagnosis, or treatment. Consult a qualified healthcare professional before starting any exercise program or making changes to your training, supplementation, or medical care. WHO IS IT FOR Everyone. One tool, whatever you are training for. HybridO.S. meets you where you are, whether you are chasing a first pull-up, a new PR, a race, a stronger back, or just trying to move well around a busy life. Built for anyone tired of static plans that ignore real life. SUBSCRIPTION DETAILS A free 7-day trial is available for new subscribers.
