Log a set in a tap
The current set lives in a tan-bordered card with an inline check. Tap to log; swipe to edit or clear. Your cursor is always exactly where you left off.

45 lb is a strength tracker for barbell lifters. Log a set in a tap, chase rep ranges, and let it nudge your next progression — all in a calm, dark interface built for the rack.
Free to start · Pro from $4.99/mo · iPhone · iOS 17+
One warm-tan accent does the whole job — highlights, progress, active state. Everything else is greyscale and shape. No neon, no streaks, no badges begging for your attention. Just your lifts.
Everything a working set needs. Nothing it doesn't.
Every interaction is tuned for real between-set use — fast, glanceable, forgiving of sweaty thumbs.
Rep ranges that nudge you up
Target a range like 8–10 instead of a single number. Hit the top on every working set and 45 lb suggests the next jump — double progression, automated.
A numpad for chalky hands
Weight and reps open a purpose-built pad that takes real gym numbers — up to two decimals. 210.55 or 92.50 go in exactly as loaded.
Rest that keeps time for you
Logging a set arms an inline rest ring with +15s and Skip. It survives pause and app-kill, so a resumed workout stays honest to the wall clock.
Warmups stay out of your numbers
Flag a warmup and it is silently excluded from volume, PRs and previous-set seeding. Your stats reflect real working sets only.
Real weights, not rounded ones
Log any two-decimal value with no half-pound snapping — and log 0 lb for bodyweight work. Shown cleanly as 45 or 42.50, never 45.00.
Progress
Charts drawn from your own lifts.
Weight and volume trends, a PR grid and per-exercise history — all derived from the sets you actually logged. True Σ weight × reps volume. No fabricated demo data, ever.
- Automatic PR detection with estimated 1RM
- Weight / Volume toggle per exercise
- Session-by-session history you can tap into
- Clean empty states before your first workout
A curated catalog that grows without an update.
Exercises and routine templates are managed centrally and merged on launch — so the library keeps growing without waiting for the App Store. Push, Pull, Legs, Upper/Lower and Full Body, ready to run.

Yours alone
One tap in. Your training follows you. Nobody else sees it.
Sign in with Apple — no password, no email address, no forms — and every set you log syncs to your 45 lb account. New phone, same history. Your data runs the app for you, and does nothing else: no ads, no analytics, never sold.
Private by design
No ad SDKs, no trackers, no selling. Training data is not a product.
Your account, your call
Synced to your 45 lb account — delete it and the data goes with it.
On-device first
Logged locally, synced when you have signal — dead spots in the gym don't matter.
Free to start. Pro when you want more.
