Currently, the classic apps such as iPhone Summer16 or iPhone Winter17 do not full utilise the available screen resolution on the device.
Below are two screenshots comparing an iPhone 5 on the left, and an iPhone 6 on the right:
You can see that despite the iPhone 6's higher resolution, the data shown inside the app is just scaled to fit the screen, instead of being built to natively take advantage of the higher resolution. The app shows exactly the same amount of data on each device, and the iPhone menu bar with the clock and signal etc. is enlarged and not its optimal size due to the scaling.
If I compare screenshots of another app, such as Apple's health app, you can see how the iPhone 6 (right) displays more than the iPhone 5 (left) and is built to display properly on an iPhone screen:
Note that the menu bar and clock are all properly sized and not scaled at all.
The benefit of enhancing the ServiceMax app to work like this is that we can display more data on the screen before requiring the user to scroll, and therefore saving time. It also looks more professional and fits with the look and feel of other apps installed on the device.
What is the underlying problem do you intend to solve with this idea?
How is the problem being addressed today, if at all?
