I'm about to launch a new (now free) version of my Mac app, CurrentKey, which helps you keep track of workflows across macOS Spaces and track how you use your Mac. https://www.currentkey.com It had been a subscription app (4.5 stars) pulling in a few thousand per year, but I recently decided to try to broaden its appeal and make it free. The new version will launch within a day or two (the launch build is just "Waiting for Review" in App Store connect).

#74Building Contextify - a MacOS application that consumes Claude Code and Codex transcripts, stores them in a local sql db.
The main window uses Apple’s local LLM to summarize your conversation in realtime, with some swoopty UI like QUEUED state on Claude Code.
I’ve just added macOS Sequoia support and a really cool CLI with Claude Code skill allowing seamless integration of information from your conversational history into aI’s responses to questions about your development history.
The CLI interface contract was designed to mutual agreement between Claude code and codex with the goal of satisfying their preferences for RAG.
This new query feature and pre-Tahoe support should be out this week, but you can download the app now on the App Store or as a DMG.
I’m very excited about this App and I would love to get any feedback from people here on HN!
My Show HN: from this past week has a short demo video and a bit more info:

#76just finished a organization project for my wife.
its a web app where you make boxes, add images or text of what's in the box. then get a qr code that you can tape to the box and scan to see the text or images in the web app.
hoping to make it a lot easier to look for things in the storage unit. instead of removing all the totes and looking in them. Just scan and see if the description fits what I'm looking for

#77Started working on a training plan builder after getting frustrated with trying to use an existing service (trainingpeaks) and not finding the controls intuitive enough without being a coach in their system.
I wanted something local and offline first + 10-20% better than excel, think I'm missing a few features other might find useful, but it works for my needs which has been great.

#78I have just released a map of median rents in Berlin [0]. Now I'm improving it. I want people to enter their search criteria, and get an idea of how rare and expensive their desired apartment would be.
This will help people set clear expectations for their apartment search.
