The growing number of mobile platforms and devices shows that implementing an app for just one platform is not the right choice. In Selleo we are developing cross platform applications – hybrids. Hybrids are built and packaged like native applications and, therefore, can be distributed through channels such as Apple App Store or the Google Play Store for Android Devices. To successfully develop and maintain cross-mobile applications we are using a PhoneGap framework. It allows us to reduce development expense and shorten development time, compared to native apps with the access to most native functionalities.
