Basically, I would like more things that I can read over a coffee or while waiting for a train or so on, so basically this is a thread for apps that provide reading material in Japanese of any sort, which you could fire up and actually read something in under fifteen minutes
. (No study/dictionary apps please).
If anybody has a nice suggestion for movie/book/game reviews in particular, I would be overjoyed, but I am an omnivorous reader and will give just about anything a go.
All the below have both Android and iPhone versions, although I'm on Android personally. Since I'm in the UK, I don't expect anything here to be region-locked but there may be oddities depending on where you are and what language your phone is set to.
SmartNews
ニュースが快適に読めるスマホアプリ『SmartNews』
(They do have a US version so you may need to change the settings in-app). This is a pretty nice news accumulator. You can pick/exclude categories. Some of it is less news and more clickbait, but that's okay, too. "Smart" mode downloads while you're on wifi so you can still read when you don't have signal.
Simplog
http://simplog.jp/portal
Ameba (blog site) portal for basically posting (as far as I can tell) pictures of what you are wearing/eating today, or what your cat is doing, with a bit of text attached. To get the most out of it you need to sign up (I just used my Yahoo Japan account, pretty quick), so you can follow random people and what their cats are doing.
Warning: you may want to turn push notifications off, this is one of those apps that likes to inform you anytime anything at all happens. I thought I'd turned everything off in-app and it was still buzzing away at me so had to lock it down completely.
Comico
comico(コミコ)
Manga, basically. Various "official" ones which update weekly (each has a set update day), and "challenge" section where hopeful amateurs compete to get promoted to official status. 遠くの日は青く , which is basically a set of short, bizarre/creepy stories is worth a look - if you don't get it, the comments are usually full of theories as to what actually happened.
Side note: kind of interesting in light of the occasional wannabe mangaka who appear around here, one of the official mangaka is a French woman (although seems she's heading back to France soon).
Cookpad
iPhone/Androidのスマートフォンやタブレットアプリでクックパッドを使おう 【クックパッド】 簡単おいしいみんなのレシピが360万品
The site I spend too much time on my laptop, now also available on my phone!
This is
the recipe site in Japan. I particularly like loading it up to see what the popular searches of the moment are (right now: Christmas Cake). Some functions require you to be logged in (free), others require you to be a premium member (not free).
