Decision guidelinesDeveloping fully native applications is like buying a sports car: it’s a fun, full-featured option, but typically expensive and not always the most practical. It should be done after carefully weighing the product’s budget, the mobile app’s strategic importance, and capabilities of the current team.
Below are some guidelines to help you decide which tech stack would best fit your application. The best decision is rarely obvious and can usually only be made after a thorough cost-benefit analysis.
If you want to support tablets, TVs, or smart watches, prefer a fully native tool chainMany great non-phone features, like smartwatch UI, picture-in-picture tablet video, split-screen multitasking, etc. are difficult or impossible to implement using non-native features. While any feature can be implemented cross-platform using bridging, extensive use of bridging can make your application more complicated and expensive to maintain than necessary. If these type of cutting-edge features are important to you, prefer a fully-native solution. If you’re leaning towards something less than a fully-native solution, strongly vet its support for the features you need.
If your budget is small, prefer a web solutionThe web is standard, and there are many frameworks that can move you along very quickly. Frontend web development is one of the most common specialties, so it’s easier, and often less expensive, to staff your team this way.
If your developers are strong but your timeline is tight, prefer a hybrid applicationGreat native applications are very high quality. Like other high-quality goods, they require time and effort to build and polish. Even if you have the best developers in the world, if business conditions give you a tight, fixed deadline, native applications can be risky. Consider using a hybrid application, which allows you to iterate quickly with the web, and then once the deadline has passed, iteratively replace web content with native content if needed.
If your user base is mostly Android / Windows users, consider a progressive web applicationMost wealthy U.S. residents use iPhones where PWAs are mostly unsupported, but in some other segments of the population, Android is immensely popular. If most of your users will be on Android anyway, consider a progressive web application which can still take advantage of offline support, geolocation, push notifications, payments, Bluetooth integration, and more. At the time of this writing, many of those features will only be available on some platforms — but if that’s not a deal-breaker, progressive web applications may be for you.
If this application provides a competitive advantage for your business, prefer a fully native applicationBusiness investments are typically either tactical or strategic. If this mobile application is tactical — say, an app solely for paying bills for a real-world service — you may want to consider a less expensive option. But if this is a strategic investment — it’s intended to give your organization a long-term advantage over your competitors — you should strongly consider a fully native application, individualized to the operating system you’re running on.
If your application needs a “wow” factor, or the best user experience available, prefer a fully native applicationConsider the “wow” factors your application might provide. Imagine buttery smooth animations, drag-and-drop multitasking support on iPad, augmented reality, ease of use for the visually impaired, on-device machine learning, background processing, and more. If these appeal to you, a fully-native application is likely the best long-term bet.
If your Android and iOS applications can look and act nearly identically, prefer a cross-platform applicationAndroid and iOS applications generally shouldn’t look and act the same; their user interface guidelines (iOS; Android) are completely different. If you don’t mind ignoring many of the guidelines and developing one UI for both platforms, a cross-platform application may be for you.
If you’re just testing the market, consider a responsive or progressive web applicationWeb apps are the cheapest to create and the fastest to iterate on. If you’re not sure whether your product will be valuable to end users, it might be better to just start with a web app.
If you want Google and Apple as marketing partners, prefer a fully native applicationIf you want your app featured in Google Play or the App Store, go fully-native. Google and Apple can drive large numbers of customers to your app if they’re so-inclined. If your app is a product, where a large number of new downloads would be successful, consider fully native. But if your app is just a channel for reaching existing customers (like a utility company’s account management app), you’re unlikely to get featured, and it’s unlikely to benefit you anyway. One exception to this guideline is games: cross-platform games written using tools like Unity are commonly promoted.
If the market is very competitive, prefer a fully native applicationUsing the fully native toolchain will give you the best opportunity to adopt new technologies because you won’t need to wait for abstraction layers (or roll your own). Many innovations take a while to be ported to cross-platform tools; in the meantime, your competitors’ apps may be outperforming yours.
