Maple AI CEO here. I use an Android device myself daily. Yes, I'd like an Android app too.
It's honestly the hassle of dealing with yet another App Store. The distribution channel of the Apple App Store is better for business in general as there are many reports showing that iOS users spend more money on apps than Android users. I've seen this first hand at previous companies too.
We want to have an Android app when we have unique features the app can do that web can't. At this time, the web and iOS app have the same feature set.
Android users can do "Add to Home Screen" and get the "app" feel. That is what I have done on my device. Once the app gets unique features, we will look to bring it to the Android app stores.
