PEAK is a recovery-based training app that builds your workouts around how your body actually feels — not a fixed calendar. Using Apple Health data (sleep, HRV, resting heart rate) and user input, PEAK calculates your daily recovery score and adjusts your training intensity accordingly. The result? Smarter workouts, better consistency, and fewer under-recovered days. Instead of guessing when to push or pull back, PEAK helps you train based on readiness — reducing overtraining while supporting long-term performance. Key Features: • Recovery-based workout adjustments • Sport-specific and goal-driven programs • Personalized training plans • Apple Health integration (Sleep, HRV, RHR) • Training history and performance insights • Health & Sleep Coach with daily guidance Built for athletes who want structure, accountability, and intelligent training decisions.

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.
