We are launching on Android first because the initial target will be the mass market around the globe which has a smartphone or tablet and access to wifi or data, but does not have the funds to invest directly in tokens such as bitcoin or ethereum. This will be a zero risk opportunity for anyone who wishes to participate.
Once we have a production version on Android, we then plan to launch in IOS in the March timeframe. We do not intend on a mobile app for Windows, but anyone can earn rewards on Steemit and we will add monetization methods on our website which can be accessed via a PC.
