I made a crossword app for language learners
Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

I recently decided to try out Google Tasks as my only task management system, and while I find some things about the interface great, it really isn't suited for someone like me who has multiple lists with lots of elements on each. So, I whipped this together real fast and I can't imagine using Google Tasks without it anymore. I realized you might want it too, so I put it on the web. Enjoy :)

Well HN, I've finally produced something I think is worthy of sharing, but I didn't do it "in a weekend". Yeah, it's an iOS puzzle game. And yeah, it's a game I built because I wanted to play it rather than based on market research, so all this sort of makes it the antithesis of a popular HN post. But whatever. Still hoping for some of that patented (har har) expert HN feedback. Critique any part of it except the music. Also, PM me for upgrade codes, or I can post some here if there's any interest. Download (it's free):…

I strongly believe that every developer is a teacher and likewise. Every time you are asked to help someone else understand your code, you’ll always be grateful to be able to share your own knowledge with others. Explain Code App is the place you can make this happen! I am eager to hear your thoughts on what I have put together so far. Would love to hear your feedback! Let me know if there are any other features you would like for this site, I’m open for ideas and would love the community feedback. Here is the link: https://www.explaincode.app/

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
