Convene

This useful app, Convene collects apps such as Snapchat or WhatsApp into one place so switching between apps is easy and quick. In fact, on average apps are used for 1000 hours per year (that's 41-42 days or 11.4% of your year) so having them all in one place helps make them more accessible, quick and easy to use.
Convene includes many useful and common features such as camera and calculator but also some uncommon ones like currency convertor or dictonary.
We at Blue Iceburg (developer name) love this app and we hope you do to!
