A Quick Guide to Building Your Own Health App

Embarking on the journey of app development may seem like venturing into uncharted territories, but with the right map and tools, you can navigate this landscape with the same precision you apply in your clinical practice.

If you are a doctor like me, perhaps the purpose of you reading this article is because you want to build your health app. Maybe you are just curious.

As a doctor and hybrid software developer, I have been building medical and health apps on various platforms for years. Allow me to walk you through the steps of building a health app.

Step 1: Define the App Project

Before we dissect the practicalities of app building, it is vital to diagnose the purpose of your digital venture.

Identify the core functionality—what is the main issue your app will address? Will it streamline patient records, provide diagnostic tools, offer clinical intervention, or facilitate telehealth services? Define your target users, be it patients, healthcare providers, or administrative staff. Consider the environment—will your app thrive best on iOS, Android, or cross-platform? There are many more questions and issues you need to brainstorm.

Delve into the anatomy of your app’s design, considering user interface and experience, keeping accessibility at the forefront. This stage is about understanding the disease before prescribing the treatment.

Step 2: Charting the Technical Pathway

Without a medical degree, one can still learn to stitch a wound.

Similarly, you do not need a degree in computer science to build an app. Familiarize yourself with the necessary technical skills. Start with the essentials of product management—like triaging in the emergency room, this will help you assess and prioritize features and functionalities effectively. Then, explore the coding fundamentals. Whether you choose to understand the basics of Flutter for cross-platform development or Swift for iOS, knowing the language will aid in better management of the development process.

Step 3: Assembling the Team

If coding is not within your repertoire, assemble a team.

This team should include user interface (UI) and user experience (UX) designers. Developers and engineers are the hands that perform the procedure under your guidance. Your knowledge in coding, no matter how basic, will be the lighthouse guiding the development ship through foggy waters.

If you know how to code, would you be able to build your app alone? The answer depends on the scale of the app you are building.

If you are building small to medium enterprise apps, maybe you can get away with being the solo developer, as long as you have the time and technical skills to execute such a task, like some minor to medium surgeries where you can safely (and ethically) execute on your own.

For bigger projects, however, just like open heart surgery, having a development team will help you just as much as having a trained operating team – you cannot operate on a patient alone, despite how skilful of a surgeon you are.

Step 4: Planning the Project

Just as you would not proceed with surgery without a comprehensive plan, do not dive into development without one. Establish clear milestones, timelines, and budget constraints. Planning is the prophylaxis against project ‘infection’ or ‘trauma’, if you will.

Remember, an app, like a patient, may not respond as predicted. Be prepared to adapt your plan accordingly. Having a plan helps you to prepare for backup work should you encounter some hiccups during development.

Step 5: Building the Project

With preparations complete, it is time to make the first incision. Begin the development phase. This process can be unpredictable—complications may arise, and you may need to pivot or adapt your strategy.

Like in surgery, remain steadfast and focused. Aim for a minimum viable product (MVP)—a version of your app with enough features to attract early adopters and validate your concept in the real world.

Step 6: The Testing Phase

Testing is the clinical trial for your app. Begin with internal testing—does the app function as intended? Are there any adverse reactions? Gradually move to beta testing with a wider user base. Collect data, observe interactions, and refine. This iterative process ensures that when your app finally goes to market, it is efficacious and ready for widespread adoption.

Step 7: The Launch!

Releasing your app is akin to discharging a patient.

After careful monitoring and ensuring stable vitals, introduce your app to the world. Launching on platforms like the App Store or Google Play is the discharge process—your app is ready to be independent, yet the care and observation continue.

Step 8: Maintaining Your App

Maintenance is the post-operative care of app development. An app requires regular check-ups and updates to remain relevant and functional. Just as medical protocols change with new research, your app must adapt to user feedback and technological advancements. There have been many instances where some code does not work as the platform updates its requirements (for example, sometimes when a new iOS version comes out), causing your now outdated app to crash or render it unusable. Allocate resources for ongoing maintenance to ensure the longevity and success of your app.

Embarking on the app development journey is not without its challenges, but with systematic planning, a dedicated team, and a clear vision, it is within reach. May this guide serve as a compass as you translate your healthcare expertise into the digital realm. Good luck!
