iOS(a.k.a iPhone OS) is known around for its simplicity and ease of use for people that are usually new to phones, or something that just works without making the user do extra steps.
While MIUI is also usually known around for the same thing, it’s based on Android and a little bit harder to use. This post shows comparisons between them one by one including all system apps.
Home Screen
iOS has a pretty simple home screen that is organized always to the top, and you can’t put icons to the bottom without putting other icons above them as icons stick to the top. Meanwhile, MIUI, it’s just like stock android, it lets you put the icons anywhere around the screen, though you still can hold an empty page on the home screen and shake the device, and the icons will arrange to top just like on the home screen.
iOS has rounded square-styled widgets which looks pretty cool compared to other Android devices. But although, MIUI also added these widgets around 3 months ago as well, so it’s a draw when it comes to comparing home screens in this case.
Settings
In the settings app of both software, they are pretty much the same except that iOS has arranged them a little bit differently which makes it look better to the eye.
Dialer/Phone
In this case, the winner is also iOS as it’s more one-handed-friendly in use. MIUI shows the extra buttons in top meanwhile iOS shows them in bottom of the screen instead, which is much more friendly to the user.
Clock App
In this one, it’s a draw because both of the software has cons. MIUI keeps the add/edit buttons on bottom which makes it pretty easy to use one-handed, but keeps sections on top just like in a dialer.
In iOS, it’s vice versa same, sections are on bottom, but add/edit buttons are on top which also makes it a little hard to use in one hand. Clock app is a draw in this one.
Weather App
This one also goes to iOS. iOS shows all needed content directly in home screen, meanwhile in MIUI you have to scroll down to see the other content inside of the app.
File Manager
In this case, winner is MIUI. iOS displays few recent items in screen as big pictures, meanwhile MIUI displays more recent items in smaller sizes, which makes the user see more items when entering the app.
Calculator
In this one, MIUI also again wins. iOS is just a simple calculator without any additional features meanwhile MIUI has some additional features in it’s calculator, which makes it better.
Sound Recorder
This one is a draw. Both of the software looks pretty much the same in design and use, and they look both pretty simple.
Music App
In this one, iOS wins. MIUI provides it’s online content section only for china users meanwhile iOS provides it for globally which is for anyone around the world.
