SLAB is a voice-first workout tracker and food logger, built for lifters who hate fumbling with their phone mid-set and calorie counters who don't want the friction. Speak naturally. Say "225 for 5, felt heavy" or "200 grams of chicken breast" and SLAB logs it. No tiny buttons. No number pickers. No friction. HOW IT WORKS - Talk to SLAB like a training partner - It parses your voice into structured data - It tracks your calories, workouts, goals, PBs and previous weights, times, and durations - One tap to talk, then back to lifting BUILT FOR THE GYM Your hands are chalked. You're wearing wrist wraps. You're between sets and your rest timer is running. You don't want to tap through forms and scroll number pickers. SLAB lets you log with your voice and get back to work. TRACKS WHAT MATTERS SLAB remembers your personal bests and what you lifted last time. See your progress without digging through spreadsheets. ZERO FLUFF Dark mode only. No gamification. No confetti. No cartoon mascots. Just your lifts, your stats, your progress. SLAB Pro unlocks unlimited voice logging and full training history.
