I like how easy it was to see where my code changes were compared from previous builds in real-time - this saved me countless times during coding! The fact that they have an iOS app makes everything even better as sometimes Android apps are too glitchy or unresponsive.
Sometimes when trying out new features of their website (like uploading images) takes forever which gets frustrating especially if working at home. Maybe give them feedback about improving speed? A great option to use while keeping track of all our applications' versions across different platforms; not just PC but also mobile devices such as iPhones and iPads.
