![]() ![]() Even most soft keyboards have different modes for each orientation, and some users prefer one or the other for data entry. ![]() Some devices have physical keyboards that force either landscape or portrait mode. As an app developer, you must consider that your software will be run by a variety of physical devices and users with different usage patterns. In order to best serve your users, you need to take into consideration all the other ways they use their devices, not just the laboratory ideals of your app.įor example, on Android, all apps should have both horizontal and vertical layouts. Your decision should take into account the target platform and it's local norms. Do your homework when building your app and figure out if they make sense for yours, but don't put in bells and whistles that really don't add value. There are LOTS of reasons why multiple orientations make sense for applications. That being said, don't use this as a carte blanche to never program for additional orientations. I would advise not to program for an additional orientation unless there's a functional advantage to it. If there's no real advantage to using the app in landscape (assuming portrait is the default) mode, why make your users try to decide which one is best? Don't force your users to make a decision that isn't necessary, especially if it's one of little consequence (in my opinion). Simply because the device has the ability to display in either portrait or landscape mode doesn't mean that your app should use both of them. I'd mostly agree with on this one, but I'd take a slightly different approach: Apps should only be programmed to use multiple orientations if they would be useful in multiple orientations. Why didn't yelp provide a landscape mode? But Yelp doesn't implement landscape mode, and as a result, I search slower. The keys have much larger surface area in landscape mode. Even though I've been using it for over a year, I always find my self trying to get landscape mode when opening up the soft keyboard to search. And even if portrait mode is optimal, why wasn't landscape mode implemented for those that prefer landscape? (The coding is actually quite easy - I've done it before). Are there more subconscious reasons why I prefer using Youtube in portrait mode? Je ne sais quoi. The portrait mode fits more screenshots on the viewport than landscape mode. Youtube does not provide a landscape mode and I've never really desired to use that mode? Perhaps when I scan for a video, I only look at the screenshot. Why did the following two iPhone apps force people to use only the portrait orientation? Youtube Under what circumstances should a mobile app only have one orientation? That is, when you flip your phone landscape or portrait, the view does not adjust. ![]()
