How many developers developed it? Just myself, I hardly slept enough during building it, but it paid off :D

How much time it took? I started in April, but started coding enf of May

You started earning? Yes, 2 paying customers, very very minimal but that prooves the need I think

How are you advertising? Hard, still trying to market to it

Why not people call from there phone for international call? It's expensive; this is a cheaper option for sure.
