A dedicated engineering team for gym apps and fitness systems
A gym wins a member once, then earns or loses them every month afterward. The member who stopped showing up is a subscription about to lapse; the class that filled up with no booking system became a crowd that pushed others to quit. And an app built once does not solve that forever: plans change, classes and trainers shift, new-year and post-Ramadan seasons rearrange the peaks, and the rule that caught a churning member last year no longer catches them today.
So we do not sell a project that ends. Kader gives you an engineering team that understands gym economics: renewal rate, churn, class utilization, and cost per acquired member. The engineers are employed and supervised by Kader and work from our engineering center in Amman, under an MSA and SOW, on a weekly sprint with a demo and a report of what shipped and what is next. Have an app running that needs changes and maintenance? Kader Hours. Have a roadmap that needs a team every week? Kader Squads.
Challenges we solve
Member churn and non-renewal
A member who fades out gradually goes unnoticed until the subscription lapses without renewal, and without automatic attendance tracking it's hard to intervene in time. And the rule that catches churn is not set once: your gym's numbers define it, and a standing team adjusts it in the next sprint.
Overcrowded classes with no booking
Group classes filling up without prior booking create crowding and member frustration, and make it hard to manage each class's capacity and trainer. The capacity and waitlist logic changes with every new class, trainer, and season, and that is a team's job, not a delivery line item.
Managing subscriptions and payments by hand
Tracking renewal dates, varied plans, freezes, and payments on spreadsheets or paper causes billing errors, lost revenue, and disputes with members. And every new plan, freeze rule, or payment gateway means new engineering work: a team that knows your gym ships it in days.
What we build for Fitness & Gyms
- A branded club app on iOS and Android: class booking, schedule and trainers, subscription tracking, and a digital QR entry pass, evolved with every season and new plan
- A membership and subscription system supporting daily, monthly, and annual plans, with auto-renewal, payment via mada and Apple Pay, and subscription freezing
- Member attendance tracking and drop-off alerts, with rules tuned to your gym's numbers rather than to an assumption, so you can step in before a subscription lapses
- Class and trainer management: each class's capacity, trainer assignment, waitlists, and post-class member ratings
- An operations dashboard and reports that follow management's questions: revenue, renewal rate, churn, and most-attended classes

Frequently asked questions
Does the app help reduce member churn?+
Yes, it's one of its core goals. The system tracks each member's attendance automatically and alerts you when activity starts to drop before the subscription ends, so you can reach out at the right moment. And the rule that decides when to step in is not set before launch but after it: we read your numbers and adjust it over time, and that is weekly work, not a screen delivered once.
Does the system support different plan types and sections?+
Yes. We build a system that handles multiple plans from daily to annual with freezing and upgrades, and supports separating men's and women's sections with independent permissions and schedules, plus a unified dashboard giving management a full view. And every plan or section added later is new engineering work, owned by the team assigned to your account.
We already run a club app and membership system. Can you take over their development?+
Yes. We read what you have, then develop and extend it without a rebuild you do not need. If what you need is changes and maintenance, Kader Hours is enough; if it is a continuous roadmap that needs a team every week, Kader Squads; and if you are building a long-term engineering department, Kader Offshore. Get in touch and we will agree the right route.
