6 Pack Promise

The features used in application:

 In-App purchase

 Scheduling Notification

 Audio Ducking

There is no back-end in this app. I love this project because I figured out all functions and solutions by my own. This project was built by native platform originally, I built cross-platform version and launched successfully. The main challenge while the project development was to ensure the application performance such as audio, video, timer functionality on the background state and killed state even. The toughest challenge was to handle audio ducking while going back and forth from background state to active state. The goal was to lower background app volume while going to the background state and increase back while coming back to the active state. For that, we concluded to go with react native audio ducking library, but it didn’t support Android while having no issue with iOS. So, it was the biggest tricky issue we faced, and I decided to customize react native audio ducking library. Throughout the deep investigation, I found the solution to resolve in the library. I worked on the native layer codebase of the library and implemented it well. It was successful obviously. The outcome of my in-timely action was the successful launch of the project but also great feedback from the app beta testers and live users.
