I have an idea for a mobile app, what should I do next?

#techmax_button_65d95a68deb19 { color: rgba(255,255,255,1); }#techmax_button_65d95a68deb19:hover { color: rgba(204,32,45,1); }#techmax_button_65d95a68deb19 { border-color: rgba(204,32,45,1); background-color: rgba(204,32,45,1); }#techmax_button_65d95a68deb19:hover { border-color: rgba(141,13,23,1); background-color: rgba(141,13,23,1); }
