What is your idea of a Android app development? A set of boring pages that confirms the seriousness of the company by its mere existence? And that's just because competitors already have website, which means you need them too? This perception is not uncommon. But this is good news for you. Until competitors realize the marketing potential of corporate inline marketplace, it's easier to get ahead.
APP development is an investment in business. When we get down to business, they always bring image and financial dividends. Professionalism plus an integrated approach is the formula for success. Don't let it let it become an equation with unknowns.
