Oh boy there are so many differences between these two that I'm not entirely sure I can list out everything, but let me see what I can do. Here's a list of differences between IOS and Android.

1. IOS was created by Apple and Android was created by Android inc. but was purchased by Google .

2. IOS is exclusively available to only Apple devices like iPhones, iPads and iPods but android is available for all phone companies which want to use it.

3. IOS is closed but has open source components, android is completely open source.

4. IOS can't be modified easily unless the phone is jail broken, android can be modified easily.

5. IOS requires the app iTunes to be installed on a laptop before you can share media with ii through a USB, android only requires a USB

6. iOS has face time, android doesn't support it.

7. iOS browser is Safari, android browser is Chrome

8. With IOS you can't download apps from anywhere but the apple app store(not easily at least), with android you can download apps from different places

9. Android has multiple AI voice Assistants, iOS only has Siri

10. The latest Android version is Android P, the latest iOS version is iOS 12

11. Androids usually have large batteries, iOS phones usually have small batteries that are well optimized.

12. Androids have file managers, iOS phones do t have file managers

13. Androids are very susceptible to malware attack, iOS phones almost never get attacked by malware because you can only download apps from the app store.

14. Android is available in 100+ languages, iOS is available in 34 languages (these values are only as accurate up to December 2017)

15. Android updates come out quickly on Google devices but are slow to reach others, ios updates reach apple phones super fast seeing as only Apple phones use the OS.

16. Android is based on the linux OS family, iOS is based on the OSX and UNIX OS family.

There are other differences but in my opinion, these are the most important ones..

I hope this helps.
