RXd is a native iOS workout tracker built 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, all on your iPhone, all offline.
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, no trial timer, and no data leaving your phone.
Unlock RXd Pro with a one-time in-app purchase to remove the 30-day history cap, set custom targets per movement, and export your full training log to CSV. Pay once — no subscription — and Pro unlocks permanently on every iPhone signed into the same Apple ID. Athletes who installed RXd before the Pro launch are grandfathered in automatically.
Built 100% with native Apple technologies — SwiftUI-style components, SF Symbols, SF Pro Rounded, native bottom-sheet pickers, Dynamic Type, and full light/dark mode — RXd feels like an app Apple could have shipped, not a hybrid wrapper around a web view.
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 — 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.
• Pro Unlock (one-time) — Lifetime Pro purchase, no subscription. Unlocks unlimited workout history, custom targets per movement, and full CSV export of your training log.
PRIVACY BY DESIGN
Every workout you log lives on your iPhone. RXd has no backend, no account system, no login, no cloud sync, no analytics, and no crash-reporting SDK. Workout data is persisted locally with MMKV and never leaves the device. The only network surface in the app is Apple's StoreKit, used solely to fetch and validate the Pro in-app purchase. The App Privacy form on the App Store 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 across the year, 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 and want a fast, native, private workout tracker that respects your time, RXd is for you.
