I’m a nerdy, tech person who thinks the advent of mobile devices of a great thing. Personally, I think just taking out your phone or tablet to take notes or add something to your calendar is much more convenient than turning on your computer (since unlike a computer, you can take your phone anywhere. Even with a laptop, you can’t just whip it out at the store when you think of something). Here are some stuff I’ve used to help keep things in order.
(And no, I’m not getting any sort of compensation for mentioning these. I just like them!)
I'm currently learning Spanish with this. It gamifies the entire experience, if that's your thing. There is a mobile app for iOS and Android. It's lacking in Asian languages (there's only Vietnamese right now), but they're adding Japanese right now.
It's a little pricey side, but so worth it if you're a website builder or do coding things. 😍 Also Mac OS only unfortunately. So far I haven't found anything comparable (which is why I haven't starting coding on my Windows computer).
I mostly use this for the LESS compiler, but it can also minify your code, so you're not loading gigantic JS and CSS files on your sites. Also it's hilarious (the site is hilarious, the images are hilarious).
So if you haven't started learning another language with Duolingo yet, you're missing out on the hilarious/wtf sentences it has you translate. 😀 Here is a good sampling of them, for your viewing pleasure.
A great time waster. This site is like Wikipedia. You start on one page (like say your favorite TV show) and then find yourself clicking through a chain of like 4 or 5 links. Then you'll go "wait, how did I go from American Girls to Abnormal Ammo?"
