Because I'm still working on the Android / Android Wear version, I haven't done a ton of marketing yet. I did have business cards printed up with the URL, logo and some screenshots, and have been handing them out to random people :) For monetization, I offer a subscription that costs $11.49/year; with that you get an account enabling your data to be stored on my servers and thus accessible to all your devices, including the web. Without an account, the app itself is free (with all features included), but the data is only available on your device (unless you manually export/import to other devices, which you can using the app).
