Arnie: Gym Logger & RPE

Arnie is the gym logger that disappears during your working set. Built for barbell lifters who hate fighting their app between sets. Open Arnie, hit the bar, log in two taps, rest. No menus, no social feed, no streak guilt. Why lifters pick Arnie - Barbell-first keypad: plates auto-calculate, last set pre-fills, repeat with one tap. - Inline half-point RPE chips (7, 7.5, 8, 8.5, 9, 9.5, 10) right next to the reps field, no modal. - RIR logging if you prefer it, with autoregulated load suggestions for your next set. - Per-lift e1RM tracked automatically, so intensity stays honest across rep ranges. - Rest timer that starts itself the moment you log a set. Per-muscle volume math - Weekly hard-set counts per muscle group, color-coded against editable MEV, MAV, and MRV landmarks. - Autoregulation cues when a muscle group is under-stimulated or buried in junk volume. - Mesocycle planner with progression, deload, and periodization logic you control. - Tonnage per lift, per session, per week, no spreadsheet required. Strength progress, visualized - Automatic PR detection across reps, weight, e1RM, and tonnage. - Per-lift strength curves with rolling intensity. - Anatomical heatmap of weekly volume distribution. - Advanced stats: fatigue trend, frequency, set quality. A real exercise library - 1323 exercises with form GIFs, plus unlimited custom exercises. - Supersets, bisets, trisets, drop sets, warm-up ramps, all first-class. - Templates you build once and reuse forever.
