Denshi jishos always seemed cool but I could never justify them over just having my phone around.
I have 大辞林 installed on my phone. I can highlight words within definitions to search those (similar to ジャンプ). If I ever need to write a kanji, I use the handwriting feature in google translation then copy to my preferred dictionary. 大辞林 doesn't have voice, but if you're using a J-J dictionary you should be fine on that front and obviously a phone has backlight.
If you're on Android you can use Google Play Rewards to rack up free (if you're fine with pimping out your metadata) credits to buy the app. As far as I'm concerned, I have feature parity on my phone without any added expense.
My first language is portuguese, but I'm also able to read most english and write some basic stuff in english. (I don't mind using JP->EN instead JP-PT).
Is this app Daijirin? There is a 81% off sale, but no device I got is compatible with it. lmao (Why this app isn't compatible with devices? Seriously... lol :I) https://play.google.com/store/apps/details?id=jp.ne.biglobe.daijirin.gp&hl=en
Japanese to japanese dictionaries wouldn't help at this exact moment, but I'd buy that to use in future.
Atm, I'm kinda stuck at N5 or N4... because I can't memorize kanjis and it is kinda driving me nuts.
$400 on an EX-Word? Last time I saw them online, because I couldn't find them in local stores, the cheapest was $599... It is a kinda big investiment, that why I asked. (not that $400 is much better)
I think I'll buy some books and an used one. Any budget, yet good, brand that is worth buying? and/or JP->EN&EN->JP app worth having?
J-J dictionaries usually point out what means what in such situations. 大辞林 does it and from what I can see, weblio does it as well. And of course, in cases where neither shows any information, you can always do a google search where most of the time the first result is a question in chiebukuro, where somebody explains it in detail.
