Crucible: Strength Tracker

Bring your coach's spreadsheet, a creator template, or a classic split into a real tracker — with RPE, technique tags, and progressive-overload history.

Bring any written program — your coach's spreadsheet, a creator's template, or a legendary split — into a modern tracker. Crucible turns a static spreadsheet into a live, progress-tracked training app.

Most trackers make you rebuild your program by hand, tap by tap. Crucible is built around import. Point it at an .xlsx or .csv — even a messy one — and it reads your days, exercises, sets, rep ranges, and rest, fixes Excel's habit of turning "3x5" into a date, groups multi-week blocks, and drops you into a clean review before anything is saved. Running 5/3/1, nSuns, GZCLP, PPL, or PHAT? It's in the app in seconds.

BUILT FOR SERIOUS LIFTERS

• Spreadsheet import (.xlsx / .csv) with smart column detection and a review-before-save step
• RPE / RIR effort logging, warm-up sets, and last-set techniques (drop sets, rest-pause, myo-reps)
• Per-set notes, supersets, tempo, and time-based sets
• Focus mode: the set you're on stays front and center; everything else folds away
• A muscle heat-map of your weekly volume, so you can see what's being trained
• Automatic personal-record detection (including rep PRs on bodyweight lifts) and a progressive-overload history for every lift
• "Last time" recall so you always know what to beat
• One-tap logging — check an untouched set to repeat your last; the rest timer starts itself and runs on your lock screen
• Plate calculator — exact per-side loadout from the plates you actually own, in pounds or kilograms
• Full kg support — switch lb ⇄ kg anywhere in the app

PLAN ON A REAL CALENDAR

• Programs map onto actual calendar dates — start Day 1 on any weekday, or pick up mid-program
• Drag to reorder days, add rest days, and see your week at a glance
• A clear dashboard with your next workout front and center
• A consistency streak and weekly-volume view that reward showing up — with optional "time to train" reminders
