I feel like the three plaforms are living their own independent lives...
I use both iOS and Android devices and Android updates come more often than iOS - the total feeling, design and functionality of these two apps are different, with some features missing. Are you even improving the iOS app? And then there's the web version.
Any plans no making the total experience more standardized, meaning you get the same features and functionality, regardless of the platform? I could write a long list of features that are available to one platform only.
