What LiftProof actually does

Three pillars. No fluff.

Every other strength app picks one and calls it a product. LiftProof does all three because getting stronger needs all three.

  1. 01 · Track

    Log a set in five seconds.

    Thumb-zone controls, haptic feedback, an RPE picker that takes one tap. The Ledger keeps the pace of your actual training, not a menu tree between every rep.

    See the Ledger →

  2. 02 · Program

    Run the program. Or build your own.

    5/3/1, Linear Progression, Upper/Lower, PPL, GZCLP. The app adjusts weight targets from what you actually lifted, not a prescribed ramp that ignored you.

    Browse programs →

  3. 03 · Progress

    See strength move. The bar, not your step count.

    Twelve-month trend lines per lift. Plateau signals that mean something. No AI narration, no vague wellness score — just the numbers that map to the iron.

The Monument · Set execution

One set. One weight.
Readable from the rack.

Monument is the set-execution sheet. Massive tabular weight number, reps dialed with a thumb, RPE picked from 1 to 10 in a single tap. It appears for a single set and gets out of your way.

  • 114pt weight digits. Tabular numerals, high contrast, no layout shift when the number grows.
  • RPE 1–10, one tap. No drop-downs, no pop-ups. Pick exertion the way you’d hold up fingers.
  • Rest timer in your pocket. Haptic taps at 30s and 10s remaining — no need to look at the phone.

Ledger workout view with completed and upcoming sets listed in one table

The Ledger · Workout canvas

The workout is
the list.

Ledger holds every set in one long table. Completed sets fade, upcoming sets sit in order, and the workout flexes to your session — not the other way around.

Reorder
Long-press to swap exercises mid-session without losing your place.
Substitute
Squat rack taken? Swap in a close variant and keep the volume plan intact.
Drop set
Add a set inline. The program still learns from what you actually did.
Freestyle
Start from an empty Ledger and build the session on the fly. Still logs to history.

Programming

Programs that adapt to
what you actually lifted.

Five starter templates plus custom. Every program reads your last session and adjusts load and volume from your actual performance — not from a prescribed ramp that ignored you.

The science

Programming choices you can
check the math on.

LiftProof's defaults draw from the published strength literature. Every recommendation cites its source. Nothing masquerades as medical-grade certainty, and nothing here is a medical claim.

Read the methodology →

  • 01

    Volume landmarks (MEV · MAV · MRV)

    Weekly set targets per muscle group sit inside the evidence-backed landmarks for a lifter at your training age.

  • 02

    RPE autoregulation

    Set-level RPE feeds back into the program so a bad day adjusts the next session — not a rigid percentage grid.

  • 03

    Stronger-by-Science reference data

    Tier progression pulls from Greg Nuckols’ published percentile dataset. Every tier jump cites the source.

Who it's for

Intermediate lifters who want their programming to pay off.

  • "Finally an app where the logging keeps up with my pace. Three exercises in, I stopped thinking about the app and started thinking about the bar."

    Marco R.

    U/L split · 4 years lifting

  • "The trend line on my squat finally showed me why I was stalling — I was undertraining volume, not pushing through a plateau."

    Priya S.

    5/3/1 BBB · 6 years lifting

  • "No cloud, no account, no leaderboard. Just the numbers that map to the iron. Exactly what I wanted."

Common questions

Everything you'd
email support about.

Answers to the 12 things people actually ask before downloading. Still have a question? Help center →

What does LiftProof cost?
$10 per month or about $80 per year (roughly 33% off) with a 7-day free trial through the App Store. One price, everything unlocked. No tiers, no upsells.
Is there a free version?
Yes. The free tier lets you log workouts and track your last 30 days of history. Paid unlocks unlimited history, programs, and advanced analytics.
How do I cancel?
Cancel any time in Settings > Apple ID > Subscriptions on your iPhone. Your data stays on your device either way.
What platforms does LiftProof support?
iPhone, iPad, and Apple Watch. Native SwiftUI, iOS 17 and later.
Is Android coming?
Android is not on the 2026 roadmap. The focus is making iOS the best strength app shipping. One platform, done well.
Does it work with Apple Watch?
Yes. The Watch mirrors the main set-logging view so you can tap through reps and read the rest timer without pulling out your phone.
Does it integrate with Apple Health?
LiftProof reads heart-rate and workout signals from Apple Health for in-session context. We never upload your health data to our servers.
Can I export my data?
Yes. Paid plans include CSV export of every logged set, rep, and weight. The data is yours.
Where is my data stored?
On your device, in Core Data. There is no LiftProof cloud to leak. iCloud sync between your own devices is opt-in.
What programs are supported?
Popular templates like 5/3/1, Linear Progression, PPL, Upper/Lower, and GZCLP, plus custom programs you build yourself. More programs land every month.
Can I use LiftProof for freestyle workouts?
Yes. Freestyle is a starting temperature, not a mode. Tap "Freestyle workout" on the Today tab to build a session on the fly.
Who is LiftProof built for?
Intermediate lifters who want their programming to pay off. If you care about adding weight to the bar over the next 12 months, this is your app. Not for casual workouts or class-tracking.
