About
GYMTROX is the member app for gyms that run on GYMTROX. Your gym adds you, sends your login key on WhatsApp, and the app opens in your gym's name, logo and colours, with your membership, check-in pass, classes and workouts in one place.
Your gym pass
See your package, days left and expiry date the moment you open the app. Renew in the app where your gym offers it, and keep every receipt and invoice under My purchases.
Check in with a QR code
Show your pass at the door and you're in. Your check-in history, attendance and streak grow with every visit.
Classes and personal training
Browse your gym's timetable, book a place in a class, and book sessions with your gym's trainers.
News from your gym
Timings, holidays and offers arrive as notices from your gym, so you never miss a change.
Your gym's community
A monthly leaderboard of members by days checked in, a monthly challenge, friends and stories. It starts again every month, so anyone can reach the top.
Plan and track your workouts
Build a weekly split from a ready-made plan or design your own. Log sets, reps and weight as you lift, with personal records picked out for you and your full session history kept.
