If you own a smartphone, then you know what mobile apps are. You download them from app stores and install them on your mobile device. They’re engaging, easy to use, and always at your fingertips.
Mobile apps leverage your smartphone’s built-in features. For example, Google Maps relies on GPS tracking to plan routes in real time, and AR games like Pokémon Go use the camera to engage players even further.
The market of mobile apps continues to grow year after year. Experts predict that by 2029, global mobile app revenue will increase to $782 million. Gaming remains the most profitable niche, closely followed by social networking apps. If you’ve been thinking about launching your own mobile app, now is the perfect time.
Now, let’s look at the benefits of mobile apps for a business.
Mobile apps can achieve higher user engagement rates compared to web apps. One big reason for that is push notifications — they give users reminders and motivate them to check back in the app. Another reason is the high performance of mobile apps. The fact that users install them on the device, makes the in-app experience quick and seamless, increasing user satisfaction, and therefore engagement, even further.
Native mobile apps take advantage of built-in smartphone functionality. For example, TikTok can access your phone’s camera, and Uber can see your location in real time. These native features make mobile apps more convenient and appealing to users.
Popular mobile apps have in-app purchases, letting users buy in-game items or remove ad banners. By now, it has also become standard for mobile platforms to offer clients premium subscriptions inside the app. If you choose this approach, consider giving your users one free month of the subscription. This way, they’ll be more inclined to pay the full price in the future, and your app will earn more revenue.
Well-optimized mobile apps load very quickly — in a fraction of a second. This can improve user retention rates since slow performance won’t frustrate people. When it comes to mobile apps, load times can make or break a product. Many people simply abandon apps if they have to sit through loading screens for more than 5 seconds.
Let’s go over some of the drawbacks of mobile apps:
Native mobile apps often take longer to build compared to web apps. Sometimes, you’ll even have to make a separate app version for each platform, which increases the development time. Also, in the case of native apps, programmers need to use different frameworks and workflows for each version, which can complicate the process.
Instead of making multiple versions of a native app, why not go cross-platform? Tools like React Native allow you to develop a single mobile app that supports both iOS and Android. As a result, you’ll be able to save a lot of money and launch your product sooner.
If you want your mobile app to succeed, you’ll need to publish it to the app stores. For Android, it’s the Google Play Store, and for iOS — the Apple App Store. Every product submitted to the app stores goes through an approval process, which takes time. And to get published, every app needs to follow strict rules set by Apple and Google, or there’s a risk of rejection.
People have to download and install mobile apps, which can be a barrier to onboarding new users. Also, people instantly delete an app if they don’t see value in it right away. To attract and retain users, we recommend making each feature as engaging as possible. It’s also important to create an effective marketing strategy to get noticed.
Developers need to work on each separate mobile app version, making improvements and fixing bugs. Because of this, maintaining native apps is often costly in the long run. That’s one more reason to develop a cross-platform mobile product. Since you’ll only need to update one app version, you’ll be able to save money on maintenance.
Web apps work just like regular websites: you can access them through any browser, on both desktop and mobile devices. You don’t need to install them on your phone — just enter the web address and you’re in.
Web apps can give you access to a huge global audience. That’s why even the largest companies rely on web platforms, from Google and Netflix to Microsoft.
If you want to create a feature-rich product for a massive audience, why not build a progressive web app? They're optimized both for desktop browsers and mobile devices. PWAs often include features similar to native apps: push notifications, offline functionality, and fast load times. Progressive web apps are the best of both worlds, combining high engagement potential with cross-platform support.
⭐ Our experience
Here’s a carbon accounting platform that we’ve developed. It’s a progressive web app that analyzes greenhouse gas emissions to help businesses care for the environment.
When creating the UI/UX, we included analytics dashboards and focused on quick user flows. We also integrated features for automatic emission calculation and PDF file export.
Everyone uses web browsers. This makes web apps highly accessible, which is why platforms like YouTube attract a massive number of users daily. And since app stores don’t regulate web apps, you’ll have more freedom in choosing a specific audience niche for your product.
Building web apps is often cheaper compared to mobile apps. You can develop a product for several platforms at once using a single codebase. This will allow you to cut back on development costs and quickly launch the app. Just make sure your webpage displays correctly on any screen size and device type.
Since web applications are essentially websites, search engines, such as Google, index them. Thanks to that, you can take advantage of SEO to make your web app more visible to users online. This can help you drive organic traffic to your platform without spending tons of money on marketing campaigns.
Every web app is based on a web server, so you don’t need to install anything on your desktop or mobile device. This helps businesses with onboarding new users and maximizing retention rates on their platforms.
One of the biggest drawbacks of web apps is that most of them don’t work without an internet connection. This can harm user engagement and lead to increased drop-off rates. To solve this problem, some progressive and hybrid apps include offline features, such as storing cached info locally on the users’ devices.
Web app performance depends on the quality of your internet connection. Also, since web apps run inside web browsers, they’re limited by their capabilities. Browsers transmit information from the web server to your device, and sometimes, this process can be slow, leading to high load times. This is especially true for feature-rich and poorly optimized web apps.
Most web apps don’t have push notifications, and this can be problematic when it comes to user engagement. Without them, it becomes more challenging to remind users about your product and motivate them to check back in.
While some web apps use things like GPS tracking and camera integration, they can’t leverage native device functionality like mobile apps can. That’s because web platforms are constrained by their browsers, which usually don’t support advanced hardware integration. Also, since web apps are cross-platform, they rarely include device-specific features as they would be too expensive to build.
Now that we've gone over the pros and cons of web and mobile apps, let’s take a look at a cheat sheet with the main differences between mobile and web apps.
Here are the key differences between web and mobile applications to help you decide:
| 📱 Mobile apps | 🌐 Web apps | |
| Audience reach | Limited, as apps need to be downloaded and installed through app stores. | Wider audience reach thanks to universal cross-platform support. |
| Development cost | Mobile app development can cost more, especially if you want to create separate native versions for iOS and Android. | The development cost is often lower, thanks to a unified codebase that works across every platform. |
| Time to market | Longer due to platform-specific workflows and app store approval procedures. | Can be launched quicker thanks to simplified cross-platform workflows. |
| User engagement | Higher, since mobile apps offer push notifications and other interactive features. | Lower, as web apps usually don’t include native features like push notifications. |
| Customization potential | Higher, as mobile apps can access built-in device functionality like GPS and camera. | Lower due to browser limitations and varying connection speeds. |
When trying to decide between developing a web app and a mobile app, it’s important to consider several key factors. Let’s go over the 3 main ones.
Do you want to create an app for every platform out there, or just for one? The sooner you answer that question, the quicker you’ll enter the market. Web apps are limited in terms of functionality, but give you access to all platforms at once. Mobile apps, for the most part, are only available on Android and iOS devices, but allow you to implement the most advanced features.
Web app development works best for all-in-one solutions with simple features, while mobile development is ideal for specialized projects with custom functionality. For example, if you want to create a social platform with only 3 core features, building a web app will let you fit into a smaller project budget and still reach your users. But if you want to make a feature-rich app with native device functionality, mobile app development is the way to go.
Web and mobile apps are a bit different when it comes to monetization strategies. To earn money, web apps mostly rely on ad banners, affiliate marketing, and e-commerce integration. Popular mobile apps tend to include in-app purchases and premium subscriptions. We recommend looking at the full range of monetization options across different platforms to decide which type of app will suit your business best.
| Monetization model | Best for | Key advantage | User mindset |
| Ad banners & affiliate marketing | Web apps aiming for wide audience reach and traffic-based revenue | Leverages the SEO and accessibility of web apps to generate revenue from a large user base | Users accept ads as a trade-off for free content. Intrusive ads can increase bounce rates. |
| E-commerce & direct sales | Web apps (primary), though mobile commerce is growing | Ideal for complex transactions, large catalogs, and users on desktop devices | The web offers a familiar, secure checkout process. Requires a seamless user flow to minimize cart abandonment. |
| In-app purchases (IAP) | Mobile apps, especially in games, fitness, and creative tools | Taps into impulse buying and the desire for instant gratification on a personal device | Users are in an "engagement mode" and are more likely to pay for virtual goods, unlocks, or consumables. |
| Premium subscriptions | Both, but a dominant model for mobile apps, e.g., Spotify | Creates predictable, recurring revenue and builds long-term customer loyalty | Ongoing, high-value content or features justify the subscription. The "freemium" model is a powerful lead-in. |
| Freemium model | Both web and mobile, a hybrid approach to drive user acquisition | The free version acts as a marketing tool, while the paid tier delivers core value | The free tier should be useful on its own, while the premium features should be compelling enough to convert users. |
At Purrweb, we’re no strangers to app development, be it web or mobile. Take a look at some of our projects.
Breath Method is a meditation app from Singapore that teaches users breathing techniques and meditation practices. The platform offers audio lessons, educational articles, and custom playlists. In this project, we designed the UI/UX and seamlessly integrated it with the backend — the result is an eye-catching and user-friendly mobile app.
Food delivery is among the most profitable mobile app niches. We've worked on OrderUp, a platform similar to DoorDash. It lets users quickly order meals and includes search filters and categories. We came up with a memorable color scheme for the app, designed an intuitive UI, and implemented a dark mode.
BioGeek allows users to view the results of their medical tests in any internet browser. When designing the platform, we focused on simple navigation and quick user flows. We managed to streamline in-app onboarding, and now users can use every feature without long-winded onboarding processes.
Cubbiq is a web app that lets users rent storage spaces in a matter of minutes. We built the MVP from scratch: created design mockups, implemented on-site payments, and developed the admin feature. In the end, the app became popular in the Asian market and continues to grow year after year.
Both web and mobile apps can help you build a profitable business. If you can’t decide between them, we recommend thinking strategically. For example, if you want to launch a food delivery service with location tracking, mobile is the way to go. Or, if you’re looking to create a social media platform for a massive audience, consider developing a web app.
If you want to launch your app in the shortest time possible, consider making an MVP, a product that includes only the essential features. At Purrweb, we can design and develop your app from scratch, no matter how complex.

A web app runs in a browser and requires no installation — users access it via a URL on any device. A mobile app is downloaded from the App Store or Google Play and runs natively on iOS or Android. The core technical difference is that mobile apps can access device hardware directly (camera, GPS, accelerometer, push notifications), while web apps are limited to browser APIs. Both can look identical to end users, but they differ significantly in how they are built, distributed, and maintained.
Web apps typically cost less to build because a single codebase serves all platforms — desktop and mobile browsers alike. A mid-complexity web app runs $30,000–$80,000. A native mobile app covering both iOS and Android usually costs 1.5–2.5x more for the same feature set, starting around $50,000–$150,000, because each platform requires a separate codebase or a cross-platform framework like React Native. Ongoing maintenance costs also diverge: mobile apps require App Store review cycles and separate OS update testing; web apps ship updates instantly without user action.
Choose a web app when your primary goal is speed to market, broad accessibility, or a B2B workflow tool where users are mostly on desktop. Web apps are well suited for internal dashboards, SaaS platforms, admin panels, and content-heavy products. Choose a mobile app when your product depends on push notifications, offline access, frequent daily use, or tight integration with device hardware like the camera or location services. Consumer-facing products with high engagement goals — fitness trackers, delivery apps, social platforms — typically need a native or cross-platform mobile app.
Neither is universally better — the right choice depends on your audience and use case. B2B tools and SaaS products often perform well as web apps because business users work from desktops and expect browser-based access. Consumer products targeting frequent, habitual use benefit from mobile apps: app store distribution creates a persistent presence on the user's device, and push notifications drive re-engagement. In Purrweb's project experience, products that tried to delay the mobile app in favor of a web-only MVP frequently rebuilt within 12–18 months once user retention data showed mobile-first behavior from their audience.
Yes, and for many products it is the most cost-effective long-term strategy. One common approach is to start with a web app (or PWA) to validate the product quickly, then build a mobile app once the core use case is proven. Another approach is to use React Native for the mobile app while sharing business logic with a web front end — this reduces duplication significantly. The key risk in building both simultaneously is splitting a limited engineering team across two codebases before finding product-market fit. Most early-stage teams are better served by committing to one platform first.
Standard web apps require an internet connection. Progressive Web Apps (PWAs) can cache content and support limited offline functionality using Service Workers, but the offline experience is narrower than native mobile apps. Native mobile apps store data locally and sync when connectivity returns, making them reliable for field use, travel, or low-connectivity environments. If offline access is a core requirement — for example, a logistics app used in warehouses — a native or React Native mobile app is the more dependable choice than a PWA.
A web app MVP typically takes 2–4 months for a focused feature set. A mobile app MVP covering both iOS and Android takes 3–6 months for similar scope, partly because App Store and Google Play review processes add 1–3 weeks to each release cycle. Using React Native can close the gap: a cross-platform mobile MVP can reach the same 2–4 month timeline when the feature set is well-defined and avoids complex native modules. Timeline also depends on backend complexity — both web and mobile apps share the same API development time, which often accounts for 40–50% of total build effort.
