A business, when beginning its mobile app development, faces one of the biggest challenges – figuring out whether to develop Android or iOS applications. Having existed for more than a decade, both platforms are quite mature at this point. As a result, both platforms offer a comprehensive feature set, and there is little that either of them can do better than the other.
For developers, it is therefore essential to cater to both strata of users while staying within the constraints of their budget and timeline. This is when hybrid apps suit developers best. With a hybrid application, you can harness the advantages of both iOS and Android platforms, and enjoy shorter development cycles, faster deployment times, and better app performance.
What is Hybrid Mobile App?
A hybrid app is a blend of native and web applications, merging the best of both worlds. A hybrid app is a web application that is encapsulated in a native app shell. Just like the native app, you can download the hybrid app from the app store, and once downloaded the app shell can connect to the mobile platform through an embedded browser- which is invisible to the users.
