The debate over whether to implement the now trendy side navigation drawer (a.k.a. hamburger menu) or stick to traditional tabbed design for a mobile website or app can go a long way. An article published on TheNextWeb summarised just when using side navigation is relevant. My take-away from all of this is that if most of the user experience takes place in a single view, and it’s only things like user settings and options that need to be accessed in separate screens, then keeping the main UI nice and clean by burying those in a side menu is the way to go.
On the other hand, if your app has multiple views that users will engage with somewhat equally, then side navigation could be costing you a great deal of your potential user engagement, and interaction with those part of the app accessed via the side menu.
