MisterM – I’m like you, always explore all the options when I get some new software. And also haven’t been using this option to avoid learning romaji. In fact where i have a deck with the answers in kana, I usually sit down with anki on my phone, and a notebook, and physically write the answers down for each card.
Ryan – Android’s awesome. for one thing, you can choose your own keyboard app. I generally use “smart keyboard pro”, which can be set up to switch between english and japanese at the tap of a button – although unfortunately it works in the “tap か 5 times to get こ” way, and is a paid app (I think there is a free version with less features). However I do also have “OpenWnn plus”, which does work via the swipe method, and if I remember rightly is free.
Not to mention the hundreds of other keyboard apps out there – give them a try till you find something that suits :)
