I'll second Openstreetmap, I use it exclusively. There's also a set of lightweight versions that are locally hosted, so I use osmap.nl if I want to quickly look at where something is. It also forces the names to the language of the server, so you can use it to improve a second language.

I use an adblocker on my phone called Blokada. It blocks adverts in apps as well as on websites, so I don't get adverts if I play something like Words With Friends for example. Also blocks adverts on Youtube which is an absolute godsend. Advertising is one of the few things I get irrationally upset about.

I make music using LMMS. It has its limitations but it's quite versatile if you're handy with it. This song was made in it for example: https://on.soundcloud.com/dTqgb

I use Betterbird for email on my PC. It's Spartan in design, which is what I'm into, and you can sign in with multiple addresses. I use K-9 Mail on my phone which has the same advantages.

I use an app called Saisonkalender to look at what veg is in season. Quite niche but it's handy for ordering ingredients for soup of the day in work.

I have a game on my phone called Lexica which is basically Boggle. It's good fun.
