CRUCIBLE

Your Program.
Your Platform.

Import your coach's spreadsheet. Log sets in seconds. Track progress over time. Crucible is the powerlifting training app built for athletes who train with a program.

Three Steps. Zero Friction.

1

Import Your Program

Upload your coach's spreadsheet: XLSX, CSV, or a Google Sheets link. Crucible reads any layout, any format, any coach's style.

2

Train & Log

See today's session. Tap to log each set. Weight, reps, RPE. Three fields, one swipe to confirm. Your hands go back on the bar, not the phone.

3

Track Progress

Estimated 1RM trends, volume charts, PR detection, and DOTS scoring. Watch your numbers climb across blocks and training cycles.

Built for the Platform

Everything You Need. Nothing You Don't.

Smart Spreadsheet Import

XLSX, CSV, or Google Sheets URL. Crucible's AI normalization pipeline reads any coach's layout. No reformatting required. Dates, exercises, sets, reps, RPE, %1RM, and target loads are all extracted automatically.

Free

Gym-Fast Set Logging

Swipe right to log a set. Swipe left to undo. Tap to enter weight, reps, and RPE. Top-set detection and PR tracking happen automatically in the background.

Free

Today View & Calendar

Open the app and see exactly what you're doing today. Day progress bar, exercise cards with prescriptions, and a calendar with training day dots for navigating your block.

Free

Progress Charts

Estimated 1RM trends over time, weekly volume tonnage, exercise filtering, and date range views. See how your strength is moving across training blocks.

Pro

Competition Tracking

Designate your squat, bench, and deadlift. Track your running total, DOTS score, and IPF GL (Goodlift) score over time. Compare against your OpenPowerlifting best.

Pro

Copy for Coach & Export

One tap copies your logged sets in a tab-separated format, ready to paste back into your coach's Google Sheet. Select which exercises to send. Export full training logs as CSV.

Your Hands on the Bar.
Not on the Phone.

Every design decision defers to the barbell. These three principles shape the rest.

Athlete-First

Every screen is designed for the gym floor. Large tap targets, swipe gestures, minimal navigation. Log a set in seconds and get back to work.

Offline-First

All training data lives on your device. No account required, no cloud sync to break. The only network call is the one-time spreadsheet import; everything after that is instant and local.

Coach-Compatible

Your coach sends a spreadsheet, you import it. No reformatting, no new platforms. Coaches using Blacksmith templates unlock unlimited free imports and backfill.
