Jamaican Apps

 I have left the island many many years ago; when beepers were still a thing and the Nokia cellphone was the phone of choice. The only colors on the screen then were black writing against the green background. Something similar to what's shown below.

I know we have jumped leaps and bounds since then. But I'm curious, is there any one phone dominating the phone market and what about apps?

Are there any truly Jamaican apps servicing the Jamaican population?  If you know any do tell.
