Startup Idea : Cluster Apps - One App for Many Apps

I have a lot of similar apps in my mobile (like for food, cab, online groceries, chatting etc.). Therefore, I need to develop a platform/app where two or more similar type of Apps can be accessed at a time. For e.g. you might have 2-3 food ordering apps, few cab apps, few online groceries apps. What if you just need to download one app and have access to all similar apps in one go. Please share your thoughts on how this can be implemented. Thanks:)
