Build vs. Buy: Should You Create Your Fertility App for Patient Engagement?

Fertility treatments are deeply personal and complex, and clinics are increasingly using technology to keep patients informed and engaged. Surveys show over 85% of health system leaders plan to invest in digital patient access tools. Fertility patients often juggle tracking menstrual cycles, medications, and appointments – tasks that “can be cumbersome without the right tools”.

Modern mobile apps and web portals can empower patients to log symptoms, receive reminders, view lab results, and follow care plans on their own. Such tools can enhance the patient experience, boost adherence to treatment protocols, and meet the high expectations of today’s consumer-focused healthcare market.

Once a clinic decides to engage patients digitally, it must face a key decision: build a custom app in-house or buy a pre-built solution from a vendor. Each path has major implications for budget, timeline, customization, patient experience, security, and more. 

While building a proprietary app may sound tempting, it carries risks of long development cycles and rapidly evolving technology requirements. Conversely, off-the-shelf patient engagement platforms come pre-configured and are updated by vendors, but may not fit a fertility clinic’s unique workflows. Below, we break down the pros and cons of each approach across critical factors.

1. Cost and Budget Considerations

Developing a custom fertility app in-house generally requires a large upfront investment. You must budget for design, coding, testing, and regulatory compliance work. For example, implementing a custom healthcare software solution often costs hundreds of thousands of dollars at launch. 

Smaller clinics may find off-the-shelf options more affordable up front, since they pay a license or subscription fee instead of full development costs. However, buying also means ongoing subscription or user fees. Vendors commonly charge recurring annual fees or per-user costs, and additional modules or higher usage levels can drive up the total cost of ownership.

In general, buying an existing solution shifts some capital expense into operating expense. You pay a known fee each year rather than a lump sum to build software. 

This makes budgets more predictable. On the flip side, a custom app has a higher initial cost but can avoid continual license fees down the road. Clinics should compare not only the sticker price, but also the total cost of ownership over several years. For example:

• Build (Custom) – Large upfront cost for development and testing. Some clinics may need to hire or contract developers, increasing payroll or consultant expenses. In return, there are no recurring license fees. In the long run, a custom solution can pay back through efficiency gains and avoidance of vendor costs.
• Buy (Pre-built) – Moderate initial cost to sign contracts and configure the system. Costs are more predictable. However, beware of extra charges: many vendors charge fees for adding users, connecting modules, or enabling integrations. Over time, subscription fees can accumulate, so it’s important to plan for those recurring costs.

2. Time to Market and Implementation Speed

Time is of the essence when improving patient engagement. Building a custom app in-house can be a lengthy process. Studies and industry experience suggest a fully custom digital health platform often takes well over a year to launch. 

The process includes requirement-gathering, prototyping, development, testing, and iteration. Many in-house projects exceed their initial timelines, especially as teams discover hidden complexities. 

• For fertility apps, developing all the desired features can easily push the timeline into a year or more. 
• This long development cycle delays the benefits to patients and can strain clinic resources.
• By contrast, buying a pre-built patient engagement solution can dramatically accelerate deployment. 
• Off-the-shelf platforms are already built and tested, so you simply configure them for your workflows. 
• Many vendors advertise that an app can go live in a few months once the project kicks off. 

Even if initial setup takes several weeks to integrate with your EHR or patient portal, it’s usually far faster than coding from scratch. 

For example, one guide notes that configuring an off-the-shelf healthcare analytics platform might take 6–12 months, whereas building it in-house can take 18 months or more. In practical terms, this means a bought solution can deliver value sooner.

3. Customization and Feature Set

One of the strongest arguments for building is customization. A custom app can be tailor-made to your clinic’s exact workflows and branding. Your developers can design the user interface, features, and data fields specifically for a fertility practice. For example, you might include a custom ovarian cycle tracker, unique patient questionnaires, or proprietary data fields that match your protocols. 

• In short, every feature can be aligned exactly with what your patients and staff need. 
• Integration with your existing systems can also be seamless, since you build the connections yourself. 
• This tight integration and alignment can improve efficiency: staff see screens and workflows that fit their routines, and patients get a frictionless experience.

Buying an off-the-shelf app means working with a pre-defined feature set. Many patient engagement platforms come with standard modules. Some even include “women’s health” or similar care pathways out of the box, which might partially cover fertility education or reminders. However, you may need to adjust your workflows to fit the software. Off-the-shelf apps allow limited customization – typically branding and minor setting changes. Deep customization is usually not possible. 

Clinics should carefully list their “must-have” features up front. If these are highly specialized, an off-the-shelf system might not support them without costly workarounds.

However, pre-built platforms do have advantages in features too. Vendors often refine their solutions through many clients, so their standard feature set may be robust and user-friendly. They also typically include educational content or workflows based on clinical best practices. 

These ready-made templates can save time, for example, launching a patient education track that you then tailor slightly. And because many clinics use the same system, there is a community of users providing feedback that shapes future enhancements.

4. Patient Experience and Adoption

Whether building or buying, the ultimate goal is to improve the patient experience. A well-designed engagement app can increase satisfaction, adherence, and outcomes. The look and feel of the app matter a lot. With a custom solution, you control the user interface. 

You can make it highly intuitive and personalized – for instance, using your clinic’s branding, tailoring language for your patient population, or adding features like personalized video messages from their doctor. Studies suggest that tailored patient-facing tools boost engagement. 

• For example, custom patient portals that integrate scheduling, messaging, and care instructions have been shown to improve satisfaction and encourage patients to take an active role in their care. 
• You could similarly build a fertility app where patients can review their treatment instructions, see lab results, or chat with a nurse, all in one branded environment.

Pre-built solutions also focus on user experience but offer a more one-size-fits-all design. Many vendors emphasize ease-of-use and standard UI/UX best practices. 

They often test with broad patient groups and refine the interface over time. The benefit is that you get a polished app interface without hiring UX designers. The drawback is less control over the look and feel. You can usually add your clinic logo and choose from preset color themes, but you cannot overhaul the navigation or user flow.

Clinics should evaluate the demo of any purchased app critically: it should feel intuitive for fertility patients. If the generic app workflow confuses patients or requires workarounds, it could hurt adoption.

Regardless of build vs buy, driving adoption requires planning. Onboarding patients, training staff, and communicating benefits are essential. Some vendors offer implementation support to help with training. If building in-house, plan for user testing and clear instructions. Always incorporate patient feedback: if your users are predominantly digital-native or have specific needs, make sure the app design reflects that. 

Patient experience goes beyond interface – consider how content is delivered. Some pre-built apps let you attach videos, infographics, or quizzes. If a custom build, you can embed any multimedia you want. The key is: engaging content + user-friendly design will keep patients using the app.

5. Data Security and Regulatory Compliance

Patient privacy and security are non-negotiable. Fertility clinics handle extremely sensitive health data. In the US, any patient engagement app must be HIPAA-compliant. This means strong encryption, audit logs, secure authentication, and Business Associate Agreements if a vendor is involved.

Data security must be a priority. Whether built or bought, ensure robust encryption and access controls. Established vendors of healthcare software typically incorporate these protections by default. 

• For example, vendors routinely use Transport Layer Security to encrypt data in transit and encrypt data at rest, and they offer a signed BAA to clients. 
• By contrast, if building an app in-house, your team is responsible for implementing security measures from day one. 
• This can be an advantage: you have full control to “bake in” compliance. 
• You can design the system to enforce least-privilege access, multi-factor authentication, and data segmentation exactly as you see fit. 
• But the responsibility is heavy; your developers must be familiar with HIPAA rules and coding safeguards.

Data protection must also consider real-world risks. Research has found that many popular fertility and menstrual apps on the market have poor privacy practices, sometimes sharing intimate user data without explicit consent. This highlights the need for clinics to vet any third-party platform carefully. 

If buying, ask the vendor detailed security questions and review their compliance certifications. If building, conduct security audits and possibly external penetration testing. Remember that even with a vendor, your clinic remains ultimately responsible for patient data. A data breach or violation can lead to heavy fines and damage patient trust.

6. Ongoing Maintenance and Support

Another major factor is who will maintain and support the app after launch. An app requires continuous updates – not just new features but also security patches, operating system upgrades, and regulatory changes. In a bought solution, the vendor typically handles most of this burden. They push out updates for you, ensuring the software stays current with the latest requirements. 

The vendor also provides user support: if an end-user or clinician encounters a bug, your team can contact the vendor’s helpdesk for fixes. This vendor support model means your clinic’s IT staff can focus on other projects instead of code-level maintenance. It also means that if new features or compliance rules arise, you get them as part of your service.

In contrast, a custom-built app is the clinic’s own to maintain. After launch, your organization must allocate resources for ongoing maintenance. That means either an in-house developer or a retainer with an app developer. They will need to fix bugs, optimize performance, and patch any security vulnerabilities. 

• For example, if a new version of iOS or Android changes how data permissions work, your team must update the app accordingly. 
• If healthcare laws change, you must modify your software to stay compliant. 
• This requires budgeting for maintenance from day one. Failure to do so can lead to system downtime or security gaps.

Key point: Buying unburdens your internal staff from technical maintenance at the cost of ongoing fees. Building gives you full control, but also full responsibility. Consider your clinic’s IT capacity. If you have a robust IT or development group, you may welcome the control of managing the app. If not, a vendor’s maintenance and support can be invaluable to keep the system running smoothly.

7. Scalability and Long-Term Growth

Finally, think long-term. Your fertility program may start small, but growth or changing needs could arise. How easy is it to scale each approach?

A well-designed custom app can be built with scalability in mind. You can choose cloud hosting, modular architecture, and databases that grow with usage. You can add new features when ready. Because you own the code, you’re not constrained by a vendor’s roadmap. 

For example, a multi-clinic health system with its IT team might develop a platform that smoothly adds new clinics or specialties over time. Investing in a custom solution now can reduce long-term licensing fees and inefficiencies as your organization grows.

Pre-built platforms also often scale well, many are cloud-native and designed to handle thousands of users across organizations. The difference is that any major new functionality will depend on the vendor’s development plans. If your clinic wants a new feature not on the vendor’s roadmap, you may have to wait or pay for a custom integration. However, the vendor typically handles database scaling and infrastructure, so your app won’t crash under growth unless you exceed plan limits.

For fertility clinics, growth can mean many things: a higher patient load, adding new service lines, or merging with another practice. A custom app can flexibly accommodate these changes if planned well. An off-the-shelf solution will accommodate growth up to its design limits. In practice, both approaches can work long-term; just be clear on how each handles scale:

• Does the vendor charge per patient or a flat fee at higher tiers?
• Can your in-house infrastructure handle double the patient load?
• Can the app support multiple clinic locations or languages if needed?
  

Answering these will guide the choice.

8. Weighing the Pros and Cons

Both paths have merits. Here is a summary of key trade-offs:

Building Custom (In-House):

• Pros: Fully tailored to your clinic’s needs and branding. Tight integration with existing EHR and systems. Potentially stronger competitive differentiation. You control updates and privacy. May save money long-term on licensing.
  
• Cons: High initial development cost and effort. Long time to deploy. Requires skilled developers with healthcare and HIPAA expertise. Ongoing maintenance and compliance are your responsibility.

Buying Pre-Built (Vendor):

• Pros: Rapid deployment. Lower up-front investment with predictable subscription costs. Vendor provides support, updates, and security patches. Built-in HIPAA compliance and tested user interface. Lower risk for smaller organizations.
  
• Cons: Limited customization – you may have to compromise on certain workflows. Dependency on vendor’s roadmap and priorities. Ongoing subscription fees and possible hidden costs. Integration with legacy systems might require extra workarounds.
  

In other words, building gives maximum control and uniqueness at a higher cost and risk, while buying offers speed and convenience at the expense of some flexibility.
