Why Pulse
Fewer empty spots, fewer lapsed members
Gyms lose money on members who quietly stop coming and classes that run half full. Pulse makes both visible and easy to fix.
Classes that fill themselves
Booking checks capacity in a transaction. When someone cancels, the first person on the waitlist gets the spot.
Progress members can see
Streaks, weight, waist and body fat tracked in the app, and visible to their coach.
The apps, step by step
A member’s week, and the coach who keeps them on track
Every screen below is a real screenshot from an automated end-to-end test run against the live backend. Nothing is a mock-up.
The console
The front desk, sales and accounts in one console
Check members in, chase renewals and leads, run classes and campaigns, and see the money. Every change is validated by the server and audited.
The studio today
Who is inside, today’s check-ins, renewals due, revenue and leads.
Door and desk check-ins
App QR check-ins appear live, next to peak hours and floor occupancy.
Check in at the desk
Search by name, ID or phone. Expired and frozen members are refused with a reason.

This is the full automated test report for Pulse. The production build was started on its own database and a robot used the apps and the console exactly as your customers and staff would. Each screenshot below is one step of that run, in order, with what it proves.

Built to be trusted
Membership rules your staff never have to remember
The backend checks every action, whether it comes from the member app, the trainer app or the front desk.
- Member status is computed, never typed, so it is always right
- Expired or frozen members can’t check in or book
- Class capacity is checked inside a transaction
- A cancellation hands the spot to the first person waiting
- Renewals stack on the current end date and add PT credits
- Trainers see only their own clients; their notes stay private

FAQ
Questions buyers ask
Does it work for yoga, CrossFit and dance studios?
Yes. Classes, rooms, levels and coaches are all configurable, and members book the same way.
How does the QR check-in work?
The member shows the pass in the app; the server checks the membership is live and not frozen, and logs the visit for the front desk.
Does it work on Android and iOS?
Yes. The member and trainer apps are one React Native (Expo) codebase that builds for Android, iOS and the web.
Can members renew from the app?
Yes, once a payment gateway is connected. Renewals stack on the current end date and add the plan’s PT credits.
Is it ready for real members?
The product is complete and tested end to end. To go live you connect an SMS provider for OTPs, Razorpay for payments and your hosting, and a door scanner for the QR pass. That package covers all of it.
Do I get the source code?
With a source licence or launch under your brand, yes: all three apps and the backend, with setup docs and the automated test suite.
