Reject Git-push if you haven't practiced your Spanish today

Hi HN! I made this app out of necessity: sometimes I'll troll over my laptop all day without moving until lunch break or work is done. No good. So I made git hook to block my git commits if I didn't do some calisthenics. Later, after I noticed it was useful, I decided to open it up for others. It works like this: - Download the iOS or Android app - Install the .git hook - Do daily pushups with the app or else your hooks will fail Pushup form is validated via ARKit/MLKit and the accelerometer and I only use github for authentication. If you find it useful, let me know! Justin

Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

Hi! Wanted to share the project I really wanted to have. TLDR; this app lets you create your own list of words and you get a Duolingo-like experience (kind of, still needs a lot of features) practicing those words in their context. My English is not the best but not the worst either. But I realized I can't boost it up after a certain level! In my belief, in order to truly learn a language, you need to be exposed to that language often. Vocabulary is the key factor here if you really want to improve in any language. My experience is that when I read a book to improve my English vocabulary, I…

Hello ! David from Spain here :) I built TransLite because I was tired of breaking my flow every time I needed to translate something before sending it. The usual workflow was: copy → open a browser tab → paste → translate → copy again → paste back. I've created a small macOS menubar app that lets you translate the current clipboard instantly using a keyboard shortcut, in any app. It works locally and supports using your own OpenAI / Claude API key. It’s intentionally simple — no accounts, no tracking, no subscriptions. Happy to answer any questions. Best regards, David

Hey! I'm Ali, and I built a tool to help me learn Spanish. There's a good amount of info in the about page, but the short version is that I found apps like Duolingo completely useless. In theory they're designed to help you speak a language but I found it mostly helped my muscle memory tap the right parts of a screen without really learning to say anything. Or more importantly prepare me for how fast a native Spanish speaker speaks! After giving up on Duolingo I tried a few different things; Pimsleur, Paul Noble and Language Transfer. These are all great in different (but similar) ways and…
