Show HN: Focusmo – A macOS focus timer that connects to your existing task apps
I kept losing focus not because I lacked discipline, but because starting a focus session had too many steps: open the task app, pick a task, open a separate timer, set the duration, start. By step 3 I was already on Twitter.So I built Focusmo — a native macOS app that pulls tasks from the tools you already use (Things, Todoist, TickTick, Reminders, Google Tasks, Microsoft To Do, Obsidian) and lets you start a timed focus session on any task in seconds.The core idea: your task list and your focu

Hacked my chess ELO ranking as a beginner, went from 0-700 in 12 sessions
I wanted to learn chess but never started because the feedback cycle took too long. Play on chess.com, go study moves somewhere else, come back, and you probably wont even see those moves in your next game. The loop never closes.So I built Chess Rocket to hack that. It connects Claude Code to Stockfish through MCP, and Claude becomes your coach in real time. Every move gets evaluated while your playing. Blunders get full explanations, good moves get a nod. The depth of teaching scales with how b
Show HN: Preact Health
In 2018, I attended Start Up school with the intention of creating a health tech start up. It started as an EHR but in an overly crowded space and dwindling desire for “social media” platform, I trashed the idea and started something new - a basic way for people to understand their health; distilling a complex topic into something more simple and understandable.I’ve finally picked up enough technical skills (and with some coding help from AI) and data/business understanding to bring out Pre
