We decided to use Appium because it's an open-source solution that supports so many languages, including Java, Adobe, C#, and Python. That's why so many DevOps and IT people prefer it.

I used the Silk Test earlier. But I will suggest Appium over it as of now.

I have not used another solution previously.

I have used multiple automation frameworks including Nightwatch.js but most were integrated with the solution's libraries. 

We also have used Selenium, which has more information available. Selenium is also open-source. Both are pretty similar. 

I have no experience using other automation tools for our devices. We only use Appium.

I've only used Appium, and I haven't found a solution that's as good as Appium.

I wasn't sure of what other solutions existed out there. I just came across Appium, and I thought that Appium suits my use case, and it's open source, so that helps.

I have experience with Appium, Tosca, and Parasoft.

We used commercial tools like Experitest. There were a lot of limitations. For example, we had to use iOS Configuration Utility manager before using that tool. We felt Appium was better because it is an open-source tool. It is very competitive with any of the commercial tools, right now.

Before this solution, I only had experience with HPE UFT (Unified functional testing). I, later on, moved to Selenium because we are able to achieve the same results with this open source solution as with any other commercial product, without any one-time or recurring cost for the tool. 

Selenium has matured with time and become a stable solution for Web Application automation. More and more clients are preferring Selenium because of the no-cost factor, and as a result, there are good job opportunities available for people who can work on Selenium. 

These were the major driving forces for me to move towards the Selenium automation solution.

Yes, Silk Mobile. Its features are very far from Appium's capabilities. Also, it is expensive.
