Call out
your gym buddy.
Free workout tracker with unlimited custom exercises and lift challenges with friends.
Call out a friend.
Outlift your circle.
Pick a lift, call out a friend or your whole crew, and race for 1 week, 2 weeks or a month. When time's up, there's a winner, and everybody sees it happen.
Send the callout
Callouts happen between people who actually train together. Send a link or an invite code. Your friend can accept straight from the link, even before they download the app.
- Only people in the callout see the standings
- 1v1 or a whole crew, top set or total volume
Every set moves the podium
Scores come straight from the workouts you log, so there's nothing to enter. The podium shows exactly how far you are from first.
- Get a ping when someone overtakes you
- Set stakes, like loser buys the pre-workout
Watch it play out, plate by plate
When time's up, the scores stack up plate by plate in the order you logged them. The loser's tower topples, the podium rises and the cards flip.
- Ties, blowouts and crew podiums get their own ending
- The push never spoils who won
- Share the final frame, then run it back with a Grudge Match
Your card, earned in callouts
Your Lift Card carries your best squat, bench and deadlift and your callout record. Win callouts to move it up a tier, and fill your trophy case with achievements like Upset, Photo Finish and the 1,000 lb Club.
Build a split that fits your training
Push, pull, legs, bro splits, or something entirely your own. Splitmaxx adapts to how you actually train instead of forcing a preset.
800+ exercises built in. Add unlimited custom exercises, free.
Log sets, reps, and weight in seconds
A fast, distraction-free logger built for the gym floor, not a spreadsheet. Rest timers and last-session prefill keep you moving between sets.
- Rest timer on your Lock Screen and Dynamic Island
- Weights and reps prefilled from your last session
- Automatic PR detection as you log
Watch your numbers move, week over week
Clean progress charts turn months of logged sessions into a clear picture of what's working, so you know exactly what to flex.

Premium is bought inside the app, not on the website.
Prices shown are in US dollars. Prices in other countries are shown in your local currency in the app and on the App Store. Premium is an auto-renewing subscription, billed through your Apple ID. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in Settings > your name > Subscriptions. Health widgets need an iPhone with Apple Health data; your Health data stays on your device. See our Terms of Service and Privacy Policy.
Frequently Asked Questions
Everything lifters want to know about splits, data, and callouts.
Can I build my own split, like Push / Pull / Legs / Upper?
Yes. Start from a preset (Push/Pull/Legs, Upper/Lower, PPL + UL, Full Body) or name your own days, then assign them to weekdays. Splitmaxx shows today's workout from your split, and you can switch it or log a freestyle session anytime.
What happens to my data if I lose my phone?
Your workouts are stored on your device first and backed up to the cloud automatically, about 30 seconds after each change. You can restore from up to 10 dated snapshots, export a backup file, or download your full history as a CSV.
How do callouts keep things honest?
Callouts are invite-only, so you're competing with people you actually train with, and standings are visible only to people in the callout. Scores only come from logged workouts, and you can report or block anyone.
What's a Lift Card, and who can see it?
Your Lift Card shows your best squat, bench and deadlift, your split, your callout record and three pinned achievements. It moves up a tier as you win callouts: Bronze, Silver at 3 wins, Gold at 8, Holo at 15 and Maxxed at 30. Only people you're in a callout with can see it.
Which health data does Splitmaxx use?
Splitmaxx reads sleep, heart rate and steps from Apple Health to power the optional Health widgets. It's read-only: Splitmaxx never writes to Apple Health.
