Three ways to use Core.X
Start with the app. Add a gym if and when you want one — and leave without losing your account.
Just the app
Everything social, on your own. No gym attached to your account.
- Global feed, follows and messages
- Goals, streaks, duels and challenges
- Leaderboard, levels and achievements
Your gym
Add your gym and the app becomes theirs too — billed by the gym, at their prices.
- Your gym's private feed and leaderboard
- Class schedule with RSVP and waitlists
- Class credits and your gym's colors
More than one gym
Keep a home gym for the branding and train at others when it suits you.
- Day passes, class packs or a second membership
- One merged “Your gyms” view, switch home gym any time
- You pay each gym directly, at their prices
This is what it actually looks like
Real screens, straight from the app on the App Store. No mockups.
One tap between everyone and your gym.
Post a photo or a clip from the session and it lands in the global feed with everyone else training today. Flip the toggle and you're looking at your gym only — the people you actually stand next to. Likes and comments on every post.
Goals you keep, day after day.
Set a goal for the day, the week, the month or the year, then tap Mark complete when it's done. Each one keeps its own progress bar, a run of dots for the last seven, and a streak badge once you've held it more than a year. Any goal can be private.
A podium worth climbing for.
Ranked on goal days, levels or attendance — across all of Core.X, or just inside your gym. The top three get the podium, everyone else gets a row, and yours is highlighted so you always know exactly where you stand.
The week ahead, booked in a tap.
Pick a day and you get every class on it — the time, the coach, how many spots are gone and what it costs you in credits. Hit RSVP and you're in. You can see who else is going before you commit.
Everything else that keeps you coming back
All of it free, all of it in the same app.
Duels & challenges
Go head-to-head with a friend, or join a challenge and see who holds up.
Messages
Follow the people who keep you honest and message them without leaving the app.
Day passes & class packs
No credits at that gym? Grab a day pass or a class pack from them — some offer a free first visit.
Local deals
Gym members unlock perks from local businesses near their gym, redeemed in the app.
Gyms on Core.X — mostly in Florida for now.
Browse their schedules, prices and what's on this month, then buy a day pass or pack straight from your phone. You pay the gym directly, at their prices.
A small, growing list of gyms — and every one of them is bookable from the app.
- Schedules you can browse before you commit
- Day passes and class packs, bought in the app
- Some gyms give your first visit free
Three steps, and the last one is optional
- Step 1
Sign up with your phone
A phone number and a code is the whole thing. No gym, no gym code, no card — you're in.
- Step 2
Post, set goals, follow friends
Share the session, set daily, weekly and monthly goals, and build a streak worth protecting.
- Step 3
Find a gym when you want one
Book a class at a gym on Core.X with a day pass, a class pack or a membership — whenever it suits you.
There's more in there

MessagesSort out who's going to the 8am without leaving the app.
Accountability calendarClasses, active days and your best streak, month by month.
Free, always
No paywall on the part you use every day.
The app costs nothing
Sign up, post, set goals, duel your friends and climb the leaderboard without paying us a cent.
Gyms set their own prices
Memberships, day passes and class packs are bought from the gym, at the gym's prices. That money goes to them, not to Core.X.
A membership ending never locks you out
Leave a gym and you keep your account: your posts, your goals, your streak, your friends and any pack credits you still have.
Put your gym in front of every Core.X user.
Scheduling, payments, CRM and analytics — plus a member community that already lives in the app, and a directory that sends new faces through your door.
