Arnie: Gym Workout Log & RPE

Arnie is the gym workout log that disappears during your working set — built for lifters who train with a barbell and hate fighting their app between sets.

SWITCH WITHOUT LOSING A REP Your training history is years of work. One-tap CSV import brings your sessions, sets, and PR history into Arnie in minutes. And CSV export means you are never locked in.

FREE WHERE IT COUNTS Unlimited workout logging. Half-point RPE. Per-muscle volume tracking. Automatic e1RM. The full 1323-exercise library. All free, no account, fully offline. Only the mesocycle planner is Pro.

BUILT FOR THE WORKING SET

• Barbell-first keypad: plate math, last set pre-filled
• Half-point RPE chips (7, 7.5, 8 … 10) inline next to the reps field — no modal
• Rest timer that starts itself the moment you log a set
• Supersets, drop sets, warm-up sets, and AMRAP flags, all first-class

VOLUME MATH DONE FOR YOU

• Weekly hard sets per muscle group, color-coded against editable MEV, MAV, and MRV landmarks
• Automatic e1RM per lift keeps intensity honest across rep ranges
• Tonnage per lift, per session, per week
• Automatic PR detection: top-set weight and set volume
• Strength curves and an anatomical heatmap of weekly volume

A REAL EXERCISE LIBRARY

• 1323 exercises with form GIFs
• Unlimited custom exercises with your own cues
• Templates you build once and reuse forever

PRIVATE BY DESIGN No account. No cloud sync forced on you. No social feed. Your training log lives on your device, works in airplane mode, and exports whenever you want.

ARNIE PRO Pro adds the mesocycle planner: block periodization with progression and deload logic you control. Monthly, yearly, and lifetime options are available in the app; subscriptions auto-renew until cancelled in Settings.
