I built an app that displays geolocations of tweets on an OpenStreetMap. That data is publicly available from Twitter and users share their location willingly, I presume. Will an app like that become illegal, as far as European tweeters are concerned?

What? Of course not. This law doesn't make apps "illegal". What the law does is put regulations around what kind of personal data you can collect and store from your users, require you to explain what you're doing with that data, and allow your users to opt out of having that data collected.

It's unclear. The GDPR definitely covers personal data even if publicly available, so just because you grabbed it from twitter doesn't make it kosher. That said, realistically, I'd have a hard time imagining you would have too much difficulty as long as you allowed people to delete their data upon request. If they post something to twitter, the obvious intent is to make it very public.

  For a real life example, there is a group of people that collect Facebook posts and process them through a ML filter which judges if the post contains hate speech, and if it does, it reports the post to the police, supposedly after manual review. Does this processing comply with GDPR? I'm pretty sure none of the people would allow this processing to take place if they were asked for permission.

    My best guess is they will be able to shut this down hard, unless there is some alternative processing basis to be leaned on. See (6)1 for a list of potential bases. So no. Not GDPR compliant in the slightest.

For your particular scenario, the main impact of GDPR would be not on your actions but on Twitter obtaining the data (which is personal information at the tweet level) and distributing it publicly to third parties like you. I don't see any clear restrictions for you, but perhaps GDPR will result in your data source becoming unavailable.
