Coming soon to iPhone
Record a lift and Klank ranks it from Iron to Titan against lifters your sex and bodyweight. Post it to the feed, climb weekly leagues and call out your friends.
App preview: a Flex feed post of a 225 lb bench press ranked Diamond I, a Gold I rank-up screen, and a weekly Beast League leaderboard.
How it works
Every set is a shot at climbing. Klank turns your training into a game you can actually win, and gives you the receipts.
Film it with the in-app camera or just log the set. Logging works offline, so bad gym signal never costs you a PR.
Your estimated max is measured against lifters your sex and bodyweight. Land anywhere from Iron to Titan, with three divisions in every tier.
Post to the Flex feed, stack XP in weekly leagues, call out your friends and drop share cards made for Stories.
The ladder
Eight tiers. Three divisions each. One question every time you touch the bar: how high can you climb?
Iron
0–124
Bronze
125–249
Silver
250–374
Gold
375–499
Platinum
500–624
Diamond
625–749
Champion
750–874
Titan
875–1000
Any set of 1 to 10 reps counts. Klank estimates your max, scales it to your bodyweight and scores it from 0 to 1,000. That's how a lighter lifter's 185 lb bench can outrank a 225.
Rank any three and you unlock an Overall rank, the one on your profile and the leaderboards.
Every tier splits into III, II and I. A new division gets a mini celebration. A new tier gets the full show.
The Flex feed
A vertical feed of real lifts from friends and the community. Swipe through, like, comment, and hit Spot when someone pulls a PR.
Every lift video is recorded inside Klank. No camera-roll uploads, no recycled clips from three years ago.
Lifters weigh in with “looks valid” or “needs a closer look.” Votes add context. They never change anyone's rank.
Recordings save privately. You choose what goes to friends and what goes public.
Follow your crew's PRs, trade form notes and talk trash in DMs with accepted friends.
Compete
Ranked ladders, seasons and trophies, like your favorite competitive game. Except the XP comes from the gym.
Weekly leagues
Each week you're grouped with lifters near your rank. Sets, workouts and PRs earn XP. Finish near the top and you're promoted when the week closes. Finish near the bottom and you drop.
Callouts
Challenge a friend on a ranked lift. Whoever improves their score the most wins, so it's fair no matter who's bigger.
Leaderboards
See exactly where you stand, by lift, sex and weight class.
Gym Crowns
Hold #1 on a lift at your gym and the crown is yours, until someone takes it.
Weekly streaks
Streaks count weeks, not days. Hit your weekly workout goal to keep the flame alive, and use a freeze when life gets in the way.
Trophy case
From your first plate to the 1,500 lb club. Streak milestones, bodyweight feats, Callout wins, and a few you'll only find by accident.

SecretFair play
A leaderboard is only fun if it's real. Klank is built to keep it that way.
Every ranked lift is recalculated on our servers. Impossible numbers are rejected, and huge jumps are held off public boards.
Profiles, posts, comments and messages can all be reported or blocked. Our team reviews reports within 24 hours.
Lifters under 18 are friends-only by default and stay off gym and global leaderboards. You must be 13 or older to join.
We don't show ads, sell your data or track you across other apps and websites. Ever.
Pricing
Everything you need to log, rank and compete is free. Klank Pro unlocks the deep cuts.

Yes. Logging, ranks for the five core lifts, the Flex feed, friends, leagues and trophies are free, with no ads. Klank Pro ($9.99/month or $79.99/year with a one-week free trial) adds more ranked lifts, bigger leaderboards and extras.
Klank estimates your one-rep max from any set of 1–10 reps, divides it by your latest bodyweight, and compares that ratio with strength standards for your sex. The result is a score from 0 to 1,000, a tier from Iron to Titan, and a division (III, II or I).
No. You can log sets without filming anything. Video is there when you want it for the Flex feed, and recordings stay private until you choose to share them.
