Your next set, already calculated.
STRONKR generates your routine, tracks every rep, and auto-progresses your weights using RPE. You show up. It does the programming.
Pick the one that sounds like you.
You have the discipline. Lose the spreadsheet.
STRONKR calculates your next weight using RPE and your last 4 weeks of history. Auto-regulated progression, block logic, real data — volume, PRs, trends — visible from session one. Strong records what you did. STRONKR decides what's next.
ProofSuggests a deload when your RPE spikes — before you stall.
Open the app. It already knows what today is.
No programming knowledge needed. Your routine is built for you, weights go up automatically every week, and every session ends with one number that proves you're moving: total pounds lifted. Week 3 you'll see something like '12,000 lbs this week' — and you'll want to screenshot it.
ProofFirst session completable with zero instructions. If you can text, you can use STRONKR.
Years away from the bar? Start where you are.
STRONKR builds a return program around your actual level, your equipment, and your recovery — not what you lifted in college. Loads start conservative and build weekly. No ego, no injuries, no feeling like a rookie. When your first PR in years lands, the app catches it before you do.
ProofProgression that respects the body you have today.
Free forever core · No credit card · Your data stays yours
Your tracker only records. It never tells you what's next.
So you end up doing the programming yourself — in your head, between sets, or in a spreadsheet at 6am.
- 01
The spreadsheet tax.
You pay for a tracker and still maintain a Google Sheet to calculate progression. That's two systems for one job.
- 02
The invisible plateau.
Same routine for months. No progress. No idea why. An app that only records can't answer 'what should I change?'
- 03
The paywall ambush.
Features you used yesterday, behind a paywall today. We've all been burned. STRONKR's free tier doesn't shrink.
There's a reason no app fixed this. Doing all three is hard.
Generate. Train. Progress. One flow.
- 01
Generate.
Answer a 2-minute onboarding — your equipment, your schedule, your level. STRONKR builds your routine. Don't like an exercise? Swap it once, it remembers forever.
- 02
Train.
Open the app. Today's session is ready. Log a set in seconds: weight, reps, RPE, done. No menus. No thinking. Works offline in any gym basement.
- 03
Progress.
STRONKR reads your RPE history and calculates your next loads automatically. Pushing too hard? It deloads you. Cruising? It adds weight. Every week, forward.
You'll never open the app wondering what to do. That's the whole point.
Built for lifters, by a lifter who got tired of updating a spreadsheet between sets.
- RPE — Rate of Perceived Exertion. How hard a set felt, 1–10. You tap a number; STRONKR does the math.
- Unlimited routines, free
- EN / ES
- Works offline
An engine, not a notebook.
RPE auto-progression.
Every set you rate feeds the algorithm. STRONKR adjusts your next session's loads automatically — up when you're ready, down when you're cooked. Coach logic, zero coach price.
Routine generator with memory.
Your equipment, your split, your preferences. Swap barbell bench for dumbbells once — it's permanent. The routine adapts to your gym, not the other way around.
PRs, detected — not hunted.
1RM, 5RM, volume records: STRONKR spots them the moment they happen. Confetti included. Your history becomes a highlight reel.
Share the session, not a screenshot of a spreadsheet.
Every completed workout renders as a clean, Instagram-ready summary. Send your routine to a friend with one link — they open it, they're training on it.
The honest comparison.
We built STRONKR because nothing else had all three.

General patterns, not a shot at any one app — if they ship this tomorrow, lifters win. Market average based on published pricing of comparable fitness-tracking apps.
The fine print, in large print.
The free tier doesn't shrink.
PRO adds features. It never takes away what you already had. No bait, no switch.
Auto-progression stays free. Forever.
It's the core of the product. Paywalling it would make us everything we built STRONKR against.

Questions lifters actually ask.
Why isn't STRONKR in the App Store?
It's a PWA — it installs from the browser to your home screen in two taps. No 30% Apple tax means more budget for features, and updates land instantly. Works offline like any native app.
What's RPE and do I need to understand it?
Rate of Perceived Exertion — how hard a set felt, 1–10. You tap a number after each set; STRONKR does the math. If you can rate a movie, you can rate a set.
Will the free tier get worse later?
No. Written commitment, section above. PRO adds; it never subtracts.
I already have years of data in Strong/Hevy.
Start fresh with your current numbers — the onboarding asks for them, and the engine calibrates within 2–3 sessions. Import tooling is on the roadmap.
I train at a barebones gym / at home.
The generator builds around whatever equipment you tell it. Swap any exercise permanently.
What happens when I travel or miss a week?
STRONKR recalibrates instead of punishing you. Come back, rate your first sets honestly, and the loads adjust.
Is my data private?
Private by default. No public profile unless you create one. No data sales, ever.
Show up. We'll handle the rest.
Your routine is 2 minutes away. Free, no credit card, no app store.
Built for people who show up.
