I use an app for the keyboard so I can change the settings so the screen is dark, as I write in bed on my phone at night sometimes. It also lets me turn off autocorrect which can be soooo annoying when typing names, etc. And I type in an app, too, then send it to myself to draft on my pc later if I want to, or copy paste it to an online wordcounter that spellchecks at the same time. The app I use is called ColorNote and the website I usually check it through is https://wordcounter.net/
