#1 Healthcare Apps Market in 2020

If you are planning to make a medical app, it’s worth knowing the market.

Industry Overview

2020 will definitely make history as the year of COVID-19. The coronavirus pandemic has made quite a splash not only in our lives but also in the health apps market. Every aspect of healthcare that has to do with telemedicine, AI, and remote patient monitoring (RPM) got a huge boost (up nearly 300% in investment, according to CB Insights).

As doctors and patients are looking for new ways to connect while keeping their distance, telehealth apps will continue to dominate the space. I’m sure we’ll see more telemedicine and RPM solutions in the near future, but let’s take a look at what’s happening with healthcare apps in the stores right now.

Statista says there are 88,000 mobile health apps in Google Play and Apple’s App Store combined, and some random research into health-related applications claimed 325,000. Whatever the case, that’s a lot of apps to compete against.

At the same time, if you check the top 100 ranking health products in both stores, you won’t notice much versatility. You’ll be scrolling through lots and lots of fitness applications, calorie trackers, period trackers, and meditation products before you get to a decent telemedicine solution like Healow or Babylon.

Top charts in Google Play: Health and fitness apps

What’s more, the sum of downloads for the top eight telemedicine apps doesn’t even scratch the surface of what the health & fitness categories generate. So focusing on the meditation and fitness areas will probably get you further if you’re targeting the general public.

And if you came up with an idea to cater to your patients, then there’s no need to look at the trending products. Just make sure you’re adequately fulfilling your customers’ unique needs.

Top 5 Successful Healthcare Apps

It seems that any list out there ranking health apps is totally arbitrary. Would you make a list based on top free, paid, grossing, or trending, based on Google Play or Apple’s Store, or maybe take into account software review platforms like G2 and Capterra?

Instead, we turned to CB Insights with their Healthcare Smart Money list that shows where top-performing VCs betting on healthcare put their money.

Healthcare deal share: investment heatmap

We then discovered this precious list of startups, each building a health app, ranging by the investment size. And surprise-surprise, the best-funded apps come from those categories highlighted in the heatmap by CB Insights.

Without further ado, here’s the list of mobile products that people who professionally invest in healthcare put money on:

The mobile app guides users through 15-minute sessions, and difficulty level gradually increases  as the sensors data indicates the progress.



#2 Must-Have Features in a Health Application

To build healthcare applications that people would actually want to use means to include features that engage users and offer them tangible benefits. Of course, the choice of features will depend on whether you want to build a mobile medical solution for glucose tracking, fitness, or, let’s say, for remote patient monitoring.

Still, there are a number of must-have features that every health application needs to be considered a success.

We'll provide insight into what tech stack and APIs work best for your app idea.

Integrations with Google Fit, HealthKit, and Samsung Health

Most healthcare apps have to deal with patient data. In that regard, services like Google Fit and HealthKit work as data hubs keeping user vitals.

Patient and doctor profiles

All app data should be organized in user profiles that patients and doctors should be able to edit at any point. Doctor profiles must include enough info about a specialist so patients can make their choice easier.

Telemedicine options

Being able to connect with care providers in real time via video calls or messaging has become a necessity if you want to develop a medical app that works at a distance.

Reminders and notifications

What mobile applications really excel at is keeping you up-to-date on your prescriptions and medicine intake. These notifications can be not only time- but also location-based.

HIPAA compliance

Of course, all PHI data must be kept secure, and the HIPAA rules that every health app must adhere to, make sure you follow suit. Therefore, it’s vital to encrypt data, provide two-factor authentication, use secure connections, and follow many other protocols to keep everybody’s data safe.

#3 The 5 Steps to Build a Medical App

Step #1: You are building a healthcare app for …

If you are reading this, chances are you already know your target audience. We’ve discovered that successful medical apps are always built by someone serving in the field: either with a medical or nursing degree or working closely with healthcare providers. You really need industry-specific insights when developing a medical software program.

Define your medical app’s audience

Get to know the potential users of your app. Their needs and pet peeves will drive every significant decision you’re about to make when building the healthcare app. Remember, it’s all about their context for using your solution:

  • Will users be standing or sitting?
  • Will they have both hands free?
  • Will they have time to interact, or will a glance suffice?
  • Will they face patients when using the app?

Who is the customer of the healthcare app you're building?

Choose a suitable platform

These and myriad of other questions will influence the features you’ll build into the health app direct your choice of mobile devices and platforms:

  • iOS or Android
  • smartphones / tablets / smartwatches / smart speakers /
  • AI integration by Google / IBM / Microsoft
  • AR, VR, or IoT integration

Let’s look at some of the most popular types of healthcare apps out there. The diagram is far from covering the whole spectrum of apps that you can build of course. Instead, it’ll help you to jump-start on your app idea quest and, eventually, will allow you to hone in on your target audience:

And by the way, thinking outside the box is always welcome. Is there a place for a healthcare app game? You bet, there’s plenty in Google Play already! Is there a place for a solution that connects to a smart pillbox and tracks medicine intake? Yes, we developed a similar product.

Step #2: Here’s how you build a healthcare app without building it

Yes, that’s right. You don’t have to throw yourself into healthcare app development right after putting together a list of features and requirements. Every line of code is money out of your pocket. Why don’t you spend it on finalizing the concept of your iPhone healthcare app first?

You do this by prototyping: fleshing out medical features into clickable screens that look almost identical to a real-life product. The beauty of a clickable prototype is:

  • you can experience it on your phone as if working with an actual app
  • you can quickly get a prototype in the hands of users for A/B testing
  • you can verify with a developer if all features are quite feasible on a selected platform

Build a Healthcare App Clickable Prototype

And all of that without draining your development budget. Despite being ultra-important when building a healthcare app, UX & UI work often accounts for a fraction of the total cost, unlike coding.

It‘s 10x cheaper to fix a design flaw while
prototyping than during development.

Today, there’s no shortage of interactive tools for rapid prototyping. Some, like Balsamiq or Proto.io, are so easy-to-use that it will be hard to resist the urge to try your hand at putting together a couple of mocks. Others, like Adobe XD or InVision, require design resources with more hands-on expertise in app development.

The bottom line is when prototyping, you’re kind of building your healthcare app, and, at the same time, you’re not. Only because at this stage, your users can’t download the product or perform any non-hardwired action in the prototype.

Step #3: Key things to consider when developing a healthcare app that will stand out

At this point, you already have all the features that your medical app will ship with. And the click-through prototype. You’re fully equipped, and nothing can stop you from plunging headfirst into the development of your healthcare app, right?

Right — in many cases, but not so fast if you’re looking to build an exceptional healthcare experience. We suggest you consider these three points, if anything, to ensure you’re building a health app that will make a real impact.

Security & Compliance

No, it’s not about the proverbial HIPAA compliance that should be in place whenever patients’ protected health information (PHI) is at play. Depending on the type and functionality of your medical app, you will need to wrap your head around such concepts as:

  • HIPAA - abstract lock with health iconsApple’s Human Interface Guidelines for CareKit and HealthKit
  • Android.os.health documentation
  • IEC 62304, ISO27001, SOC2 Type 2, and a few other standards
  • MFi Program
  • HITECH Act, GDPR, and other regulations

Patient data should always be traveling to and from the app in an encrypted format over a secure connection.

APIs & Integrations

To lure in modern power users and newbies, your app will likely integrate with other services. That’s how you leverage the location and proximity data, make use of vitals offered via HealthKit, work with EHR systems, and do a lot of other wonders with your healthcare app.

Make sure if the corresponding APIs are available for commercial use and whether you are required to open source your code after using them.

Agile & Continuous Delivery

Agile is probably already one of your mantras. Well, it’s the perfect time to start practicing. When you build a healthcare app, it’s essential to realize that proceeding by brief, one-week sprints, you’re likely to arrive at the desired destination faster and with fewer iterations. There will be time to test the completed scope and adjust future sprints if necessary.

Another aspect you should be paying attention to is continuous delivery. The team developing your healthcare app must set up an environment that allows QA engineers and you to test completed features without interfering with the development of the next round of features.

Step #4: What’s next after you’ve built a healthcare app?

What do you do with an app that’s been built? That’s right — release it to the App Store, Google Play, or distribute it to users on an ad hoc basis if it’s a staff-only medical app. That’s also when the real fun starts. Because as soon as you launch the product, you start thinking about possible future iterations.

Popular Mobile App Stores

Sneak up on users, legit

If you’re teaming up with pros to build your healthcare app, your mobile product already integrates with some analytics that gathers usage metrics. All you need to do is read and interpret this data to find the potential for enhancements:

  • you might want users to stick with the product longer
  • you want to enable users to achieve their goals faster
  • you might want to increase their spend

Whatever it is you’re trying to achieve — the app usage data coming, e.g., from Firebase or Appsee is a reliable source of insight for future upgrades.

Ask for user feedback openly

You can always integrate a customer feedback system if you want to allow users to vent their frustration with the app without leaving a negative review. To enable this functionality, take a closer look at the solutions like UserVoice or UserTesting. And it certainly never hurts to monitor and interact with user reviews you get in app stores.


Watch major OS updates

New features may also come as you update your healthcare app to support the latest OS version. It’s worth noting that even though most OS updates leave existing apps intact, updating your mobile product is always a better idea. This way, you don’t accumulate any technical debt and make use of the latest OS features.

Believe me, you don’t want to know what technical debt is (reach out directly if you do!). You just don’t want to accumulate this debt and spend a hefty budget on dealing with it later on.

Step #5: Build an ecosystem around your healthcare app

Now that your app is on track with receiving timely updates and new features (dull people call this a maintenance mode), it’s time to step back and take a look at the bigger picture. Do you see the potential for driving more value for your medical app users by extending to more platforms? Or is there a particular platform (smartwatch anyone?) that just calls for integration?


apple devices

What if users could see more detailed reports in the cloud-based version of the app — the one they could access via a desktop browser? Does it make sense to come up with a smartwatch version?

At some point, you’re bound to start noticing these opportunities. So go ahead and turn them into growth points by building your healthcare app into an entire ecosystem.

#4 How Much Does it Cost to Create a Healthcare App?

The cost of developing a health app can vary significantly: from an IoT-enabled $25,000 MVP for a pill reminder to a $60,000 telemedicine solution to a $150,000+ full-cycle practice management platform. Of course, the budget for building a healthcare app will always depend on the type of product you want to create.

One question we hear a lot is How to develop a healthcare app and not lose investors’ money?

The framework we often revert to, to help our clients optimize the ROI is rapid prototyping. The sheer fact of having a near-real-life experience with zero code always excites us. We build clickable, interactive prototypes, and then relentlessly test them with the target audience to make sure user journeys make sense.

And after we’ve verified that the solution offers an optimal user experience, we start coding it in the flesh. This approach considerably saves the budget required to create a health app.
