Run Your Gym Without
Paying Monthly Software Fees

No. NitroFIT28 is a self-hosted standalone fitness business operating system purpose-built for single-location or multi-branch physical gyms. You install it once on your own server and it serves your gym exclusively — there is no shared infrastructure or other tenants on your instance. If you need a commercial multi-tenant platform to resell subscription software to other independent gym owners, explore our Gympify SaaS platform instead.

NitroFIT28 integrates natively with ZKTeco biometric devices (WDMS/ADMS protocol) and standard RFID turnstiles via our built-in GateCloud layer. When a member's subscription is active, their access state syncs automatically to physical entry gates. Supported authentication methods include fingerprint, face recognition, RFID card, and PIN. Laravel background queues handle sync with zero-latency local caching, so gates respond instantly even during peak entry hours.

Yes. The companion app is built with Quasar Framework + Capacitor, which generates standard native builds for both iOS (.ipa) and Android (.apk / .aab). You replace the app name, icons, splash screens, and color theme with your gym's brand assets, then submit directly to the Apple App Store and Google Play Store. Our documentation includes step-by-step compilation, signing, and submission checklists.

No fees beyond your one-time NitroFIT28 purchase. Apple charges a $99/year developer account fee and Google charges a one-time $25 registration fee — both paid directly to their respective platforms, not to us. The source code, build tools, and documentation are fully included in your license.

The front-desk POS and ZKTeco biometric gate validation can operate entirely over your local LAN without internet, as member data is cached locally on the hardware device. However, syncing member status updates (e.g., new subscriptions or freezes) to connected gates, processing Stripe card transactions, and sending SMS/push notifications all require active internet access.

The fully sandboxed demo is live at nitrofit28.coderstm.com. Three pre-loaded role portals are available: the Admin Console (owner/manager view), the Member App (end-user portal), and the Public Frontend. Use the role access buttons on this page — demo credentials are pre-filled, no registration required.

The Regular License ($99) authorizes deployment on one physical location or server — ideal for a standalone gym, studio, or academy operating under a single brand. The Extended License ($349) grants unlimited deployment rights, letting agencies and franchise operators install NitroFIT28 for multiple client gyms, apply full white-label branding, and commercially resell compiled instances without paying royalties.

Yes. With the Extended License, you can strip all Coderstm references from the dashboard, member app, email templates, and public frontend. Apply your gym's logo, brand colors, domain, and app name throughout. Your clients see only your brand. We include a white-label configuration guide to make rebranding fast and systematic.

NitroFIT28 runs on any standard Linux server (Ubuntu 22.04+) with PHP 8.2+, MySQL 8+, Redis, and Nginx or Apache. It is compatible with AWS, DigitalOcean, Hetzner, Vultr, or a local on-premises server inside your gym for maximum connectivity reliability. Pre-configured Docker Compose files and a quick-start installation guide are included in every purchase.

None whatsoever. NitroFIT28 is a one-time purchase with lifetime usage rights. There are no per-member fees, no monthly platform royalties, and no feature gates unlocked behind subscription tiers. You host on your own server, you own your data, and your costs are predictable forever.

Every standard license includes 30 days of free developer technical support commencing on the purchase date. Support covers verified bug fixes in our unmodified codebase and basic deployment guidance to ensure the system is operational on server configurations that meet our prerequisites. It strictly excludes custom feature development, feature additions, styling customization, configuring third-party SMS/WhatsApp gateways, local environment troubleshooting (Docker/XAMPP), and active VPS/server setups or DevOps services. Extended licenses receive priority queue responses. All customers receive lifetime free upgrades to new NitroFIT28 releases.

All sales of our digital source code products are strictly final and non-refundable. Since unencrypted source files (.zip archives and GitHub repository access) are fully accessible immediately after purchase, they cannot be returned, de-authorized, or practically retrieved. We strongly encourage you to explore our comprehensive live sandboxes, review the detailed online documentation, and verify that your server meets the exact system prerequisites before checking out. By purchasing, you acknowledge the waiver of any statutory withdrawal rights for downloadable digital products.

No. Coderstm is a software company; we do not manufacture, sell, or ship biometric turnstiles, RFID scanners, or physical POS hardware terminals. NitroFIT28 is the software operating system that connects to them. You are solely responsible for procuring, mounting, and wiring ZKTeco Turnstiles or standard RFID gate controllers at your facility. We provide comprehensive documentation outlining ADMS/WDMS protocol connection standards for seamless software integration.

If you are paying per-member, per-location, or revenue-share fees to a hosted platform, your operational costs scale against your own success. NitroFIT28 replaces that perpetual cost with a single one-time investment. You own the source code outright, your member data lives on your server under your control, and there are no vendor feature restrictions. For most mid-size gyms, the platform pays for itself within the first 2–3 months of avoided SaaS fees alone.
