Built for Real Lifters

Thoughtful engineering for the details other workout trackers ignore—from pulley ratios to seat pin settings.

🏢

Multi-Gym PR Calibration

Train at multiple gyms? Scope your PRs and weight history per gym so different cable stacks and machine ratios never corrupt your progress.

⚙️

Machine & Seat Setup Memory

Save seat height, bench angle, pin position, and attachment notes for every exercise so you never waste a warm-up guessing your settings.

📉

Smart Cut & Bulk Phases

Track body weight and measurements with 7-day rolling averages that smooth out water fluctuations and project your goal completion date.

đź§ 

Flexible Split Scheduling

Run fixed weekly days, asynchronous N-day rotation cycles (like 8-day PPL), or sequential workouts with automatic weight & rep recall.

📸

Social Workout Cards & Codes

Share vertical PR summary cards to Instagram & TikTok, or share entire multi-day training splits using a 6-character code.
