Summary – When offline access, real-time performance and native sensor integration become differentiators, choosing a mobile app is more than a trend. It reviews key use cases (offline, push notifications, augmented reality), hidden costs (App Store commissions, multi-OS maintenance, vendor lock-in) and compares website, PWA, hybrid and native.
Solution: apply an ROI/TCO analysis framework to determine the stack best suited to your business requirements.
Choosing to develop a mobile app is not a simple matter of following a trend, but requires a rigorous analysis of your business needs. The key is to determine whether a mobile app delivers a distinctive value that neither a website nor a Progressive Web App can provide. Whether it’s native access requirements, real-time usage, or high market expectations, each option (native, hybrid, PWA) must serve your ROI and TCO objectives.
This article offers a practical analytical framework to evaluate the need for a mobile app, identify winning use cases, spot common pitfalls, and select the mobile stack best suited for performance, security, and the growth of your Swiss SME or mid-sized enterprise.
Native Value of a Mobile App
A mobile app must address specific needs for native access, offline performance, and real-time features. It is justified when mobility becomes a competitive advantage rather than just an additional channel.
Mobility and Offline Access
For many organizations, being able to view critical data or enter information on the go is crucial. A mobile app can store data locally, ensure offline functionality, and automatically sync updates.
This offline mode relies on local mechanisms (secure cache, embedded database) to deliver a seamless experience even in areas with poor network coverage. A PWA can emulate this capability, but it remains dependent on the browser and its limitations.
When your teams or customers are frequently offline, investing in a flexible native or hybrid solution ensures uninterrupted service without compromising performance or security.
Deep Integration of Native Services
A mobile app can fully leverage the device’s sensors and operating system APIs. GPS, camera, biometric sensors, and augmented reality enable use cases that are impossible to replicate on a standard website.
Supporting complex interactions, such as barcode scanning or fingerprint authentication, strengthens user engagement and retention. The mobile app thus becomes a true business tool, seamlessly integrated into the device ecosystem.
Unlike a PWA, native development allows for precise permission configuration, ensures enhanced security, and leverages scalable open source frameworks, reducing the risk of vendor lock-in.
Frequent Use and Enhanced Engagement
A mobile app fully capitalizes on push notifications to re-engage and retain your audience. Contextual, personalized, real-time reminders boost open rates and engagement.
Example: A mid-sized logistics company launched a native app for delivery tracking. This solution delivers push alerts and updates statuses in real time, reducing customer service calls by 30%. This case demonstrates that when usage is intensive, a dedicated app improves satisfaction and optimizes operational costs.
The mobile app becomes a preferred channel to establish a continuous relationship with your users and gather precise data on their behavior.
Scenarios Where a Mobile App Is Essential
Certain use cases require an app to ensure real-time service, deliver immersive experiences, or meet market demands. These contexts pave the way for measurable added value.
Instant Booking and Management
In the transport, healthcare, or hospitality sectors, the ability to book, cancel, or modify services in just a few clicks is essential. Latency and friction directly translate into lost revenue.
A mobile app connected to a scalable backend ensures instant availability updates and a touchscreen-optimized interface tailored to smartphone usage. Open, modular APIs provide the scalability needed to handle peak loads.
This responsiveness builds user trust and serves as a differentiator against competitors who rely solely on the web.
Augmented Reality and Immersive Interactions
Augmented Reality (AR) transforms the user experience by overlaying virtual content onto the real world. Whether it’s for product trials, project visualization, or enhancing a maintenance process, AR requires camera access and local processing power.
Example: An SME in the home décor sector integrated an AR module into its native app to allow customers to preview furniture in their own space. This feature generated a 25% increase in conversion rates and demonstrated that AR meets growing market demand.
Such use cases cannot be properly delivered by a PWA or a website due to sensor access restrictions and GPU optimization limitations.
Push Notifications and Retention Strategies
Push notifications are a powerful lever for keeping users’ attention. Their effectiveness depends on behavior analysis and precise targeting. A well-designed backend based on open source solutions simplifies segmentation and campaign management.
High retention rates rely on contextual alerts, personalized offers, and integrated instant messaging. This strategy is built on deep native integration, which cannot be replicated in a browser.
Measuring the ROI of push notification campaigns must take into account development costs, maintenance fees, and App Store commissions, which can reach up to 30%.

Pitfalls to Avoid and Hidden Costs of a Mobile App
Developing a mobile app without strong business alignment often leads to failure. Some use cases are better served by a website or a PWA, with more controlled overall costs.
Low Interaction and Limited Adoption
If your users only access your service occasionally, investing in a native app will result in low install rates and quick uninstalls. Development and update costs won’t be offset by engagement.
In this context, a responsive website or PWA—no App Store commissions and a shorter maintenance cycle—becomes the most cost-effective solution.
It’s crucial to analyze actual usage frequency and the importance of home screen visibility before making any technological choice.
An Already High-Performing Website
Many organizations already have a web portal with advanced features and an optimized interface. Adding a mobile app can lead to duplicated efforts and inconsistencies in the user experience.
A PWA offers an interesting compromise: it works offline, sends notifications, and can be installed without a store. Its development and maintenance costs are significantly lower than those of a native or hybrid app.
Before migrating to a mobile app, evaluate the potential to enhance your existing site and measure the impact on engagement and retention.
Maintenance Budget and Store Fees
Beyond the initial development cost, you must budget for maintenance across multiple OS platforms (iOS, Android), regular updates, and security monitoring. These recurring charges typically account for 15% to 20% of the annual build budget.
App Store and Google Play commissions, as well as compliance and validation constraints, impact timelines. These factors are often underestimated during decision-making.
An in-depth TCO analysis allows you to anticipate these hidden costs and objectively compare native, hybrid, and PWA options.
Decision Framework: Native, Hybrid, or PWA Focused on ROI/TCO
The choice between native, hybrid, and PWA should be based on a framework evaluating ROI, TCO, and technological risks. A solid decision framework guides you toward the most performant and scalable solution.
ROI and TCO Assessment
For each option, develop a comprehensive cost estimate including development costs, store commissions, multi-OS maintenance, and marketing expenses for acquisition and retention.
Example: A medical SME compared a PWA and a native app for an appointment booking service. The PWA had a 40% lower TCO while still meeting real-time requirements. This comparison demonstrated the effectiveness of a methodical framework.
This quantitative approach justifies the investment to the CFO, CTO, and executive committee by ensuring alignment with key metrics.
Technical Comparison and Vendor Lock-In
A native app uses platform-specific languages and frameworks (Swift, Kotlin), whereas hybrid solutions (Flutter, React Native) share a single codebase. PWAs, on the other hand, rely on standard web technologies (HTML, CSS, JavaScript).
Open source limits vendor lock-in and facilitates evolution. Choosing a modular, community-driven framework reduces the risk of a proprietary vendor being discontinued.
The robustness of the mobile stack should be assessed in terms of longevity, automated test coverage, and security to prevent vulnerabilities and ensure smooth maintenance.
Security, Scalability, and Stack Selection
Security requires fine-grained permission management, regular dependency updates, and code reviews. Microservices architectures and secure APIs are recommended to isolate critical functions.
For scalability, a modular design allows you to add features (AR, payments, geolocation) without impacting the existing base. Open source frameworks provide an evolving and maintainable foundation.
By combining these criteria, your decision will be based on a clear trade-off between cost, performance, longevity, and business fit.
Optimize Your Mobile Strategy with an Informed Choice
Embarking on a mobile app project requires upfront validation of its added value compared to a website or PWA. Use cases demanding native access, real-time interactions, or immersive experiences justify an app. Conversely, for low usage or an already high-performing site, a PWA may be more cost-effective. Finally, a structured ROI/TCO framework guides the choice between native, hybrid, or PWA based on business objectives.
