Moka pot coffee is definitely strong. If that's your only coffee maker, I'd just dilute that with more hot water.
An Aeropress is less concentrated in my experience, and it's pretty easy to use. I prefer iced coffee unless it's cold out, so I fill the collector with ice before I brew. The melted water dilutes it nicely, in my opinion.
At the moment, you can do that, but not with an app hosted on the Play Store. I use a git client to sync my notes between my computers and my phone. But I had to get the app from FDroid, because it required the read all files permission to track changes.

I'd say this is the case for Amazon as well, if you have an actual Kindle. I was able to convert my whole library to standard epubs last weekend using Calibre.
