SCI-CO is the strength training platform that connects serious lifters with independent coaches — and gives both sides the tools they actually need. Whether you're chasing a new PR, programming for a team, or building your coaching business, SCI-CO replaces the spreadsheets, group chats, and PDFs with one structured app. — FOR ATHLETES — • Find your coach. Browse coaches by specialty — Powerlifting, Bodybuilding, CrossFit, Strength & Conditioning, Sports Performance, General Fitness — filtered by location and price tier. • Follow real programming. Workouts land on your calendar with sets, reps, and target loads. Tap a day, train, and log it. • Track every max. Your 1RMs live in one place and update as you progress. • Build on your own. Not ready for a coach? Create your own workouts, save templates, and program your own training. • See the trend. Workout history and completion stats keep you honest. — FOR COACHES — • Build a template library. Create workouts by muscle group, category, and difficulty. Reuse them across athletes and groups. • Schedule with one tap. Date-driven assignment lets you push a workout to an entire group on the day it should happen. • Run multiple groups. Personal clients, team athletes, online cohorts — manage them side by side with completion tracking. • Sell your programming. Set a price tier and billing interval. Monetize your expertise without juggling Stripe, Sheets, and DMs. • Stay in the loop. See who completed what, who's falling behind, and who's ready for more volume. — WHY SCI-CO — Most fitness apps are built for solo users or for big-box gyms. SCI-CO is built for the in-between: the independent coach with 5–500 athletes, and the lifter who wants someone in their corner without paying for in-person training. Everything in the app is designed around the actual coach-athlete loop: program, assign, log, review, repeat. — FEATURES — • Coach discovery with specialty, location, and price filters • Group subscriptions with flexible billing • Muscle-group-aware workout builder • Date-driven assignment flow • Max tracker for all standard lifts • Workout history and completion stats • Sign in with Apple, Google, or email • Built for iPhone with a fast, dark, no-nonsense UI — PRO — Athlete Pro unlocks unlimited workout logging, full max history, and AI-generated programming. Coach Pro unlocks unlimited templates, group scheduling, and athlete sales. A free trial is available. Subscriptions auto-renew until cancelled in your Apple ID settings. Train smarter. Coach better.
