Apple iOS
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.
Basically, softwares are categorized into two (2) main categories and these are;
I. Proprietary software: it's also known as a closed-source software and it can be defined as any software application or program that has its source code copyrighted and as such cannot be used, modified or distributed without authorization from the software developer.
II. Open-source software: it's a type of software in which end users are granted the permission to use, study, modify, copy and share the software with its source code anyhow.
An Apple iOS is an example of an operating system that has the open-source software features and as such its users are faced with minimal restrictions on application development.
This ultimately implies that, if you wanted a smartphone with the fewest restrictions on application development the smartphone operating system you should choose is Apple iOS.
