I’ve been using flutter + android studio and I’m enjoying it (as much as you can while making a mobile app). Android studio is a lot but it includes android emulators which is nice to test stuff on if you don’t feel like getting your phone.
You’ll need to install flutter (works on windows, mac, and linux), android studio (I think vscode also works?), and you can download a sample project, open it, build it, and run it. It’s a great way to see how it works. Then you can create your own project and go from there. Flutter has a lot of packages which I would recommend at looking through (if your app is simple you might not need any of these though).
Once you build and run the app on your android phone, it’s there and you can use it. You don’t need to upload it to google play or anything else (unless you want to share it).
I think some comment bots are nice, like the TLDR / summarization bot, reminder bot, youtube piped links, maybe one that replaces an amp link with the original? But these bots should be labeled as bots in settings so users have the option to toggle off seeing them.
I don’t like having bots post posts though, I’ve seen some in other instances and there’s not much discussion happening in the comments a lot of the time.
I’ve been writing notes about how to do certain things in some programming languages, how to do certain things on the command line, etc. and I have all this in Obsidian for my own reference. I started a blog a few months back (a static website generator) and I don’t expect many people to come across it as the things I write about are pretty niche. But it’s something that I can put time into now so when future me needs to reference something, it’s just there (rather than haphazard notes that I will need to piece together).
Self-hosting (or hosting on github) using a static website generator like Hugo can be fun if you also like tinkering around with the blog itself. Otherwise yeah there’s Medium, WordPress, maybe even Substack?
My Time at Portia (farming / exploring), Coral Island (farming / exploring), Monster Sanctuary (catching monsters / exploring), and Travellers Rest (manage a bar, and there's co-op) are so good.
