Sound familiar?

Stop coaching out of spreadsheets and DMs.

  • Programs in a spreadsheet that falls apart on a phone.
  • Lift videos buried in your DMs.
  • Check-ins in a form nobody fills out.
  • Payments chased by text.
  • Progress tracked in your head.

Knurl puts all of it in one place, built around how strength coaches actually program: blocks, top sets, RPE and the lifts that matter to each athlete.

Start your free trial

Program

Write a week in minutes, not hours.

A program builder that thinks in blocks, top sets and RPE, because you do.

The program builder: last week's training and the latest check-in above this week's four days, written side by side.
  • Your way of writing. Percentages, RPE, RIR, straight weight, or a range they work up within.
  • Top sets and backdowns. Backdowns come off whatever they actually hit that day.
  • Every lift on its own max. Close grip runs off close grip, not comp bench, locked in for the block.
  • Copy with progression. Next week is last week, moved forward, in a couple of clicks.
  • Everything else. Supersets, rest times, exercise notes, cardio, and strongman events for time or max reps.
  • Smart suggestions. Knurl learns the accessories you like on each day and offers them first.

Train

An app your athletes will actually use.

Your name and logo on it. Every set they log lands with you.

  • Works offline in the gym and syncs when they are back online.
  • RPE with a quick tap or typed in, and a rest timer between sets.
  • Video straight from their camera roll to you.
  • PRs and total weight lifted at the end of every session.
  • Progress charts they can check themselves. You choose what they see.
  • No app store needed. It runs in any phone's browser and installs to the home screen.
The athlete's app: this week's days, which are done and which is next. A training day in the athlete's app, each exercise folded to what was asked: 3×4 at 395 lb. The athlete's progress: squat going up 1.0% a month, plus or minus 0.7, with every session plotted on the trend.

Review

Coach the lift, not just the logbook.

Every finished session lands in one queue, with what matters already flagged.

Review: one session opened with its time, sets and total lifted, the row with two sets over RPE expanded, and the queue of sessions beside it.
  • Planned against done. What you wrote next to what they did, set by set.
  • Problems flagged. Misses and sets that went harder than planned stand out.
  • Real video tools. Half speed, frame by frame, and drawing right on the paused frame.
  • Side by side. Put two clips of the same lift next to each other and play them together.
  • Feedback in the moment. Pin a comment to the exact second. They tap it and the clip opens there.
  • One word on the day. Leave a note on the whole session. They see it at the top of the day.

Progress

Know who is getting stronger. Prove it.

Real statistics on every lift, explained in plain words.

Progress: estimated max for squat, bench and deadlift with each trend, the squat's chart opened showing a dot per session and the fitted band, bodyweight from check-ins and weekly tonnage.
  • Every session counts. An estimated max for each lift, built from every session they train.
  • Plain-English trends. Going up, holding or slipping, and by how much a month.
  • No false alarms. Knurl will not call a trend until there is enough training to back it up.
  • Early warning. When a weight they have handled before starts feeling harder, you see it before their max drops.

Why Knurl

Built for strength. Not for "workouts".

Most coaching apps are built for personal trainers. Knurl is built for strength coaches: the ones who write in blocks, care about the top set and want proof their athletes are getting stronger.

Built by a coach

Made by a strength coach, for strength coaches.

Knurl is built and run by a powerlifting coach who programs real athletes on it every week. Every feature is here because a coach needed it on program day, not because it looked good in a pitch deck. Questions go to a person who coaches, not a ticket queue.

Questions coaches ask

Do I need a credit card to try it?

No. You get 60 days with every feature and no card on file. Subscribe only if you want to keep going.

Do my athletes pay anything?

No. Athletes use Knurl free. If you charge them through Knurl, the money goes straight to your own Stripe account and Knurl takes nothing.

What do my athletes need?

Just their phone. The Knurl app runs in any phone's browser, installs to the home screen, and logs with or without signal.

Can I bring my athletes' history with me?

Yes. Import their past training from Excel, Google Sheets or CSV and their progress charts start with real history. The file is read on your computer and never uploaded.

Is my athletes' data private?

Yes. Their videos are stored privately and only they and their coach can watch them. Athletes own their training, and if coaching ends you keep a read-only record of your work together.

Is this an AI coach?

No. You write the programs. Knurl does the maths with real statistics, and tells you when there is not enough data to say anything yet.

What happens after the free trial?

Subscribe in Settings to keep coaching. If you do not, your coaching tools pause until you do. Your athletes can keep training, and nothing you have written is deleted.

Can I cancel anytime?

Yes, from Settings. No contracts. You keep access until the end of the month you paid for, and you are never charged again.

Your athletes deserve better than a spreadsheet.
