An app as considered as your coaching brand

A custom product does not need to look like a generic fitness platform. Its tone, content and member experience can be shaped around how you coach and how you want to be recognised.

We can take care of the path to launch

Building the app is only part of the journey. If you prefer to stay focused on coaching, Avantra can guide or manage the technical launch through Apple's App Store and Google Play.

Your app can be published through accounts owned by your business, while Avantra takes care of the technical submission and release work.
  • Developer account setup guidance
  • App identifiers and signing
  • Build preparation
  • App Store and Google Play submissions
  • Store listings, descriptions and metadata
  • Store screenshots and required assets
  • Privacy information and questionnaires
  • Review-process and rejection support
  • Release management
  • Future updates and version submissions

You always know what is happening.

Your brief becomes a clear live delivery plan. Every change is linked to that plan and posted to your project's Slack channel as it happens, so you never have to chase for an update.

  • Dedicated project communication channel
  • Live, current delivery plan
  • Visible progress throughout development
  • Completed work, current priorities and next steps
  • Feedback captured directly into delivery

Every project is led directly by an experienced senior engineer. Product, architecture, quality, release and security decisions get senior oversight from the start.

  • Direct access to the person leading delivery
  • Mature processes that improve speed and consistency
  • Automation supports expertise, never accountability
  • The same professional standard at every project size

You focus on coaching. We handle the technical side.

  • Testing and quality assurance
  • Security considerations
  • Hosting setup
  • App Store submission
  • Google Play submission
  • Launch support
  • Production monitoring
  • Ongoing maintenance
  • Future improvements

Practical questions, answered clearly

A serious product decision should come with clear terms, visible responsibilities and no hidden assumptions.

Discuss your questions
Who owns the app and source code?

The agreed ownership and intellectual-property terms are documented in the project agreement. Avantra’s intended standard is that the client owns the commissioned product and source code once contractual payment obligations are met, subject to any clearly disclosed third-party components or licences.

Can the app be published through my own accounts?

Yes. The preferred arrangement is for the app to be published through Apple Developer and Google Play accounts controlled by your business.

Can Avantra submit the app for me?

Yes. With the appropriate access and information, Avantra can manage technical preparation, submission, review support and release on your behalf. Apple and Google retain final authority over account and app approval.

What if I do not have developer accounts yet?

Avantra can guide you through setting up the required Apple Developer and Google Play accounts and explain their third-party fees. Those fees are not included automatically unless your agreement says otherwise.

Can I manage programmes and content myself?

Yes. Administrative tools or content management can be included where they create value for your project.

What ongoing services might be needed?

Hosting and third-party services depend on usage and product requirements. Any expected ongoing services will be explained before implementation rather than hidden inside vague recurring fees.

Can I add features later?

Yes. The delivery model is designed to support continued improvements after the focused first release.

What happens after launch?

Support, maintenance, monitoring, store updates and feature development can continue through separately agreed work or an ongoing product partnership.

How is data protection handled?

Security and UK GDPR requirements are considered during planning and implementation. The exact approach depends on the data collected, product functionality, third-party services and your business responsibilities. Avantra does not make legal guarantees.

Will it handle health-related information?

Potentially, but the product and compliance approach must be designed around the precise type and sensitivity of the information involved. Medical-device or regulated-health compliance is not assumed unless it is explicitly scoped.

How quickly will I see something?

Avantra aims to put a focused working version in your hands quickly, often within days for suitably scoped projects. The full timeline depends on scope, integrations, store-account setup, existing systems and compliance requirements.

Do I need to fund a large platform from the start?

No. The first release is shaped around the smallest useful product that can create meaningful value for your business and clients. That can make the starting point more accessible than commissioning a broad platform upfront. Where the opportunity calls for something larger, the scope can expand around the business case rather than forcing every client into the same package.

Start small. Grow from there.

Your coaching app doesn't need to begin as a huge platform. Start with the part that creates the most value for your business and your clients, see it working, and build from there.
