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.
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 →02 · Program
Run the program. Or build your own.
Starting Strength, nSuns 5/3/1, Upper/Lower, PPL, GZCLP. The app adjusts weight targets from what you actually lifted, not a prescribed ramp that ignored you.
Browse programs →03 · Progress
See strength move. The bar, not your step count.
Trend lines per lift, from four weeks to all-time. Plateau signals that mean something. No AI narration, no vague wellness score — just the numbers that map to the iron.
See analytics →
Inline logging · Set execution
One screen.
No set modal.
Logging happens on the set row itself. Weight and reps take ± steppers or a docked keypad, RPE unfolds in place, and last session's set repeats with a single tap.
- One-tap repeat.The quick-log chip logs last session's set, weight and reps included, before you rack the bar.
- RPE 1–10, one tap.The picker unfolds on the row. No drop-downs, no pop-ups. Pick exertion the way you'd hold up fingers.
- Rest timer in your pocket. It runs on the wall clock, keeps counting while the phone is locked, and taps you when rest is up.
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.
Nine built-in programs, 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.
Browse all programs →nSuns 5/3/1
5 wkA high-volume 5/3/1 derivative on training maxes and AMRAP top sets. Five days, structured periodization.
View program →Starting Strength
12 wkRippetoe's novice linear progression on the big barbell lifts. Add weight every session that worked.
View program →Upper / Lower
8 wkFour-day split. Hypertrophy volume mid-week, intensity day one and four.
View program →Push / Pull / Legs
6 wkSix-day rotation. For lifters who can recover from six sessions a week.

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."
Jon A.
Freestyle · 10 years lifting

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?
Every new install starts a 7-day free trial of the full app — no account, no card up front. After the trial it is $10 per month, $80 per year, or a one-time Lifetime unlock, and your data stays on your device either way.
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 and iPad. Native SwiftUI, iOS 18 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?
Not in v1.0 — LiftProof is iPhone-first, and a Watch companion is planned for a future update. In the meantime, widgets and a Live Activity keep today's session and the rest countdown visible without unlocking the phone.
Does it integrate with Apple Health?
LiftProof reads sleep, HRV, and resting heart rate for an advisory recovery score, plus bodyweight and energy data for on-device charts. With your permission it writes finished workouts back to Apple Health. We never upload your health data to our servers.
Can I export my data?
Yes. CSV export of every logged set, rep, and weight is included for everyone — trial or paid. The data is yours.
Where is my data stored?
On your device, in Core Data. There is no LiftProof cloud to leak, and nothing syncs off the device.
What programs are supported?
Nine built-in programs — Starting Strength, StrongLifts 5×5, nSuns 5/3/1, Upper/Lower, PPL, and GZCLP among them — plus custom programs you build yourself.
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.
