Though we are big supporters of automated testing sometimes there is nothing better than manual testing which perfectly mimics the end user's experience. Automated testing is robust and can save you a lot of time but it will never really reveal the true nature of your users overall experience using your application or website.
Apart from allowing you to interact with your application as if you were an actual user, Experitest offers you a wide range of real mobile devices, Android emulators, iOS simulators and Desktop Browsers. Instead of having to keep all of these devices \ browsers onsite and worry about their ongoing maintenance in terms of charging, OS upgrades etc. Experitest takes care of that for you. You can login to the cloud at any given time, deploy and install your application on a given device and start testing it.
