1RM is a workout tracker built for lifters who want measurable progress: it records sets, reps and weight in real time, helps you build reusable routines, and highlights personal records so you can watch strength improve over weeks and months. The app pairs a clean, fast interface with tools like a rest timer, body and weight tracking, progress photos, and visual analytics to understand volume and frequency. A free plan covers basics and a 7-day history while an optional Premium subscription unlocks unlimited history, advanced charts, full PR tracking and cloud backup.

Key Features

⭐ Real-time workout logging for sets, reps and kilograms with support for supersets, warmup sets, bodyweight exercises and cardio (time and distance), plus a built-in rest timer with alerts.

⭐ A 3,000+ exercise library searchable by muscle group or equipment, with unlimited custom exercises when you need something unique.

⭐ Reusable routines and templates you can drag to reorder, group into supersets and start tracking in a single tap for fast workout setup.

⭐ Automatic personal record detection for each exercise, estimated 1RM using the Epley formula, and volume PR tracking to celebrate milestones.

⭐ Weight and body tracking with goals, measurement logging (chest, waist, arms, etc.) and progress photo uploads to visualize changes over time.

⭐ Cloud sync, CSV/JSON export, Wear OS support for wrist tracking, and customization options like dark mode and kg/lbs toggle.

Advantages

✅ Intuitive, fast interface that keeps focus on lifting and tracking rather than menu navigation.

✅ Robust analytics and charts that reveal trends in volume, frequency, streaks and session duration.

✅ 1RM is built with lifters in mind, offering coach tools, a social feed for sharing progress, and automatic PR detection to motivate progress.

✅ Cloud backup and data export give peace of mind and control over your workout history.

Disadvantages

❎ Free plan limits workout history to seven days, so long-term tracking requires a Premium subscription.

❎ Several advanced features—unlimited history, full PR tracking and advanced analytics—are behind the paid tier (Premium $2/month).

❎ Smartwatch syncing is available for Wear OS devices; other smartwatch platforms are not listed as supported.
