QOTD: What are your preferred apps?

A simple question, but one which may help others find decent solutions. What are your preferred apps in the key areas?

Mine are as follows-

Notes: Apple Notes (simple, fast and very effective)
Tasks: GoodTask (a shell over Reminders, but highly customisable and eminently usable)
Lists: Magpie (a straightforward solution that you can use how you like. Good for collections, lists, things you want to buy and planning trips)
Writing: Scrivener (a wonderful and complete solution for longer writing projects)
Finance: Accounts Pro (literally perfect for the way I manage money)
Content: Reeder 5 (spend some time setting it up and it becomes very powerful)
Freeform notes: Notability (excellent on the iPad and much better than GoodNotes in my view)
Podcast: Pocket Casts (my preference in a very crowded market)
Weather: Dark Sky (quick, accurate and easy to view)
Reading: Kindle (the app when I only have my iPhone and the Kindle Oasis when I don’t)
Music: Apple Music (love the service, not the interface)
Fitness: Apple Fitness+ etc
Habit tracking: Done
Twitter: Tweetbot
Navigation: TomTom GO / Google Maps (the latter is becoming the default for most trips)
Graphic novels: YACReader
