Nowadays most people have heard about hybrid mobile app frameworks and their advantages. There are so many of them and each promises everything you dreamed about for a cross-platform mobile applications development. The idea is nice and simple: hosting a web application inside of the user’s smartphone or tablet with the ability to have a single codebase, involve web developers, reduce costs, decrease time-to-market, and so on. However, we can see that most of the mobile applications are still native and platform specific. Why is that? Experienced developers (especially those who had a really hard time working with early hybrid applications) may notice that the real life cross-platform mobile app development process is far from perfect to make it a standard. DSR Corporation team has rich experience in PhoneGap application development and knows all (or almost all) pros and cons of this technology. In this blog we aim to summarize our experience and share the risks that should be considered when using a hybrid mobile app frameworks.
“Like Native” Still Doesn’t Feel Native
After your hybrid application is ready and deployed I bet the first complaint you will get is the performance. The modern day user has zero tolerance for even a slight delay, especially if he or she is expecting to be entertained. Just try to scroll a list in a native iOS application and then in a hybrid one: you will probably not say the hybrid has delays but it feels different and users notice that.
Additionally, if you want to use the same codebase for all platforms, then your application will look the same on all platforms. Sometimes it is good and desirable. Even if it is not, your application will still work fine. But as you may know the UX/UI guidelines are different for each platform and each user base has specific expectations on how apps work on their respective platforms. For example, an iOS user expects a “Back” button everywhere, where Android users may not find the search if you implement it using the iOS style. So when you are implementing the same UI, you are making a compromise or spending extra effort to make it different.
You Can’t Get Away from Debug
As a result, this is actually a normal case for multi-platform development when “write once, run everywhere” turns into “write once, debug everywhere.”
In a perfect world a web developer can develop a cross platform mobile app without learning anything else. Meanwhile, using a hybrid framework, please make sure the team is armed with at least the following knowledge:
- Environment configuration. At the very beginning, you can rely on a cloud build service. But sooner or later, even if you work on something simple, you will need to debug your application to make sure there will be no surprises the day before delivery.
- Native support. It would be nice to rely on an experienced mobile application developer on your team. And it will be 100% necessary if your hybrid framework does not provide something you need.
- Offline mode. Make sure you are developing a mobile application, not a mobile website. It will be nice if it works offline or at least provides a clear message that an Internet connection is required.
- Guidelines. The users will very much appreciate if you meet their expectations. Everyone likes something he or she is used to and that feels natural with how they use their device.
- Interact with others. Make sure you know and interact with typical platform applications that are used every day. Building good neighbor relationships is a good habit.
- Deployment and approval. It can be a real pain for those who are doing it for the first time. You may need to read vendor requirements carefully even before you start the development: some rules can change your plans.
Keep it Simple
Considering the fact that you are still able to use native tools and controls you may think about combining web controls with native ones. Be careful not to create a Frankenstein: the application complexity can rise so significantly that it will become a nightmare to debug and maintain. First, the native control you used will need to be considered on other platforms (there is no guarantee that it will work the same way). Second, the integration part (between HTML/JS and native) is the “richest” source of bugs: the more complex the design is, the more “fun” you will have. Third, thinking about using native controls is a good signal that you need a native application. Consider your options and make the right choice for your app.
The Apple Dependency
Another risk that you may need to consider is a high dependency on the App Store Review Guidelines. The App Store is dominating the mobile apps market, so Apple can and does dictate its rules. The Review Guidelines change quite often and, although unlikely, it’s possible that hybrid apps can get banned from the App Store at some point in the future.
Now when you are aware of the risks you may wonder if there are any reasons for you to use hybrid applications. There are many of them!
Low Cost and Quick Time to Market
If you have a limited budget and need a mobile application, using a hybrid framework may be a solution. Easier UI development will give you a cost advantage even if you are planning iOS as your only platform. Make sure to keep it simple and that your single codebase can be easily ported to other platforms without significant changes. At the same time, reducing your effort can save you precious time, so you can deploy early and have the app ready before your competitors.
Startups and Explore
If you are planning to develop a serious application that requires a lot of effort for UX/UI you may consider prototyping it first. It will allow you to have better understanding of all application usage aspects and resolve problems early. Certainly, your prototype can be a quickly developed hybrid application you can use to get early adopter feedback and demo the concept.
Web Development Forces
If you or your team are good web developers, then you can use your experience in the mobile apps as well. Choose a hybrid mobile app UI framework you like the most and do the main implementation using your favorite tools. In most cases you will not need to learn a new programming language. At the same time, you will be able to develop for additional platforms improving your web development experience.
Better Than a Website
If you are thinking about developing a mobile website instead of a mobile app, then you should consider the serious advantages the mobile apps have:
- Sales and distribution. Everyone knows about platform specific application stores that help users find what they want and allow developers to sell and distribute their apps with ease.
- Usability. Mobile apps are optimized for use on mobile devices and users expect at least the same level of usability. It would be difficult to compete with a mobile application having only a browser application.
- Works offline. Your users can work with the app even if the Internet connection is lost.
- Using device capabilities. In contrast to websites, mobile apps can utilize a full set of device capabilities.
- Popularity. Today it seems like a good habit to create a mobile app to meet user expectations.
Although we at DSR prefer to build native mobile apps because of their performance, seamless user interface, and best user experience, we have rich experience building cross-platform mobile apps as well. The latter can give you a serious advantage, but only if the related risks are considered. This is not a silver bullet, but it can be a powerful weapon on your side, if your project meets the parameters described above.
