    I tried some web tools to track my workouts (specifically, running); some (like FitTrackee) came close, but I always found annoyances. So I decided to build my own. Specifically geared towards distance-based workouts, such as walking, running or cycling.

    Hey everyone, I've made this website that I hope can help some people. The original inspiration comes from being tired of having a specific site (and finding it!!) that serves my needs for a single purpose. Straight forward tools, no fuss. The objective is to be fully in-browser, no login and if possible without contacting a remote server.

  • PingStalker – A macOS tool for network engineersNov 2025 · pingstalker.com · ▲77

    Hi HN - I’m the developer of PingStalker, a macOS utility I built to see what’s really happening on the LAN/WLAN. I live in the CLI, but when it came to discovery and monitoring, I found it limiting. So I built a GUI that brings my favorite tools together in one place. PingStalker started because I wanted to know if something on the network was scanning my machine. I also wanted quick access to core details—external IP, Wi-Fi data, and local topology.

    Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
