RXd is a native iOS workout tracker for athletes who train hard and want to log every detail: strength sessions, conditioning, and named benchmarks, with the speed and polish of a real Apple app. Drop into a workout, dial in your sets and reps with native pickers, and watch your training history build up month by month. FREE TO DOWNLOAD Download RXd free and log unlimited workouts across strength, cardio, and benchmark categories. Track sets, reps, weight, distance, time, and score. Browse the last 30 days of your training history, hit personal records, and run the 1RM calculator with no account and no trial timer. Unlock RXd Pro with a one-time in-app purchase to remove the 30-day history cap, open the Trends tab, turn on iCloud Sync, set custom targets per movement, and export your full training log to CSV or JSON. Pay once, with no subscription, and Pro unlocks permanently on every device signed into the same Apple Account. Athletes who installed RXd before the Pro launch are grandfathered in automatically. KEY FEATURES • Strength Logging — Log focus lifts and complex sessions across barbell, dumbbell, and kettlebell movements: Back Squat, Front Squat, Deadlift, Bench Press, Overhead Press, Snatch, Clean & Jerk, Push Press, Thruster, Power Clean, and more, all with set-by-set rep and weight tracking. • Cardio Logging — Track distance, time, and calories with custom targets and scores. Pick the metric that matters for the workout, log the result, move on. • Benchmark Workouts — Log your performance on named CrossFit-style benchmarks. The Girls (Fran, Elizabeth, Nancy, Lynne) and the Heroes (Murph, DT, Randy, Coe) come pre-configured with movement specs and rep schemes, so you just drop in your time or score. • 1RM Calculator — Predict your one-rep max from any set and rep range using the formula you trust (Epley, Brzycki, Wathan, or Adaptive, which blends Epley for ≤10 reps with Wathan above), then convert the prediction directly into a workout template. • Targets & PRs — Track personal records by movement (1RM, 3RM, 5RM) and compare your lifts against bodyweight strength standards. See where you stand without leaving the app. • Workout History — Every workout you log, grouped by month and filterable by category. Free users see the last 30 days; Pro unlocks unlimited history. • Native iOS Polish — SF Pro Rounded typography, SF Symbols, Apple semantic colors, native bottom-sheet pickers, Dynamic Type, light and dark mode. Built on React Native's New Architecture for fluid animations and instant launches. • Trends (Pro) — Your training history, charted. Personal-record history for every movement, strength milestones announced as you cross them, and per-movement trend charts with selectable time ranges. • iCloud Sync (Pro) — Keep your workouts and targets in sync across iPhone and iPad. Opt-in and off by default; syncs through your own iCloud account, which only you can read. • Pro Unlock (one-time) — Lifetime Pro purchase, no subscription. Unlocks unlimited workout history, Trends, iCloud Sync, custom targets per movement, and full CSV and JSON export of your training log. PRIVACY BY DESIGN RXd has no backend, no account system, no login, no analytics, and no crash-reporting SDK. We never receive your training data. Workouts are stored locally on your device. Pro adds optional iCloud Sync, off by default: turn it on and your workouts sync through your own iCloud account, in a private database only you can read. The App Privacy form reads "Data Not Collected" because that is literally true. BUILT FOR ATHLETES RXd is for the people who actually open a notebook between sets: CrossFit athletes tracking benchmark times, strength athletes chasing PRs cycle after cycle, and coaches who want a clean log of what was done and at what weight. If you train seriously, RXd is for you. Requires iOS 17 or later.

Ready90 turns your phone into a movement coach for soccer players who want to keep their knees healthy. Film yourself doing a drop jump, squat, cut, or shot, and Ready90 analyzes the knee mechanics that sports-science research links to ACL and knee injuries — then gives you clear, plain-language feedback in seconds. WHAT IT CHECKS • Landing / plant knee bend — absorbing force, or landing stiff? • Knee cave (valgus) — do your knees track over your toes or collapse inward? • Left / right symmetry — is one leg doing more of the work? • Vertical jump height — track your explosiveness over time • Rep counting with per-rep form flags HOW IT WORKS 1. Pick your movement (drop jump, squat, single-leg squat, cut & plant, kicking, and more) 2. Prop up your phone and film a few reps 3. Get a simple form score and coaching cues — tap "Advanced" for the detailed angles and research targets DAILY READINESS Log a 30-second check-in (sleep, soreness, energy) for a daily readiness score, so you can spot when you're pushing too hard. TRACK PROGRESS Every session is saved on your device — watch your knee mechanics, symmetry, and jump height trend over time. PRIVATE BY DESIGN Everything runs on your phone. Your videos and results never leave your device — no account required. Ready90 provides general coaching and training guidance based on published movement-screening research (LESS, limb-symmetry norms). It is not a medical device and does not diagnose, treat, or prevent injury. Always consult a qualified professional for medical advice.
