If you want your product or message to reach as many people as possible fast then a website is the way to go. If on the other hand you want your users to build a personalised relationship with your product, then you might want to consider adding a mobile app to your solution suite. Studies show that if your app is designed and developed well, your users are likely to spend as much as 80% more time on your app than on any other medium. Sure it takes some effort to get them to download your app, but once they do, rest assure that they're going to navigate through what you have to offer.
