I stumbled across your app entirely by accident due to the sheer amount of other mindfulness apps you have to compete with on the App Store. I've enjoyed it enough to delay switching back to Android for almost 2 months now.
I think you should take the plunge and create an Android version. Not simply for my benefit (though I will not hide the fact that being able to finally go leave the walled garden would be nice), but because of the current state of the mindfulness section of the Play store.
Right now an Android user has 2 choices: they can splurge and use Headspace which then charges them monthly or they can go with one of the quick-assembled apps that's attempting to counter Headspace, but are little more that egg-timer apps with mindfulness in their title. There's no middle path, an area that I feel this app could fill on the Play store better than it does on the App Store.
Thanks for the incredibly thoughtful post, we too have our eye on Android but are balancing it with our extremely lean team. Thanks for delaying switching back to Android … we hope to be in a position to build and support apps for both platforms over the next few months or early 2015. Please stay in touch!
I would love if this app was available for android. I have an android phone which I always have with me, I don't always have my iPad! Syncing across devices would be fantastic too!
