Fed up of ugly and weird diving apps, I built my own
Hello everybody, I am new to HN but I must say I really enjoy the vibe. I have been coding for almost 15 years now and after having fired myself 2 times in a year (both from corporate and startup worlds), I decided to dedicate full time to what I love: building cool stuff for my own, with the dream of becoming a solopreneur. Among my many passions (some dangerous), I love scuba diving. All the logbook apps I tried had these problems: - Distant from the user experience and needs. - Complicated yet useless features that no one uses. Literally no one, not even those who created them. - Ugly. -…
Fed up of ugly and weird diving apps, I built my own launched on December 9, 2024 with 12 votes, #1,362 of 5,365 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Depth Log is a scuba diving logbook app built for divers frustrated with existing applications. It replaces complicated, feature-heavy alternatives with a cleaner, simpler interface focused on what divers actually need. The app uses improved algorithms for calculating air consumption, developed with aerospace engineering expertise, rather than the naive formulas found in established diving platforms. Designed by a solo developer, it prioritizes user experience and visual design.

I built a CLI to automate depth tracking on underwater videos2025 · github.com · ▲32Hey HN, I built depthviz, an open-source CLI tool that generates depth & time overlay videos from dive logs. It supports dive computers (Garmin, Suunto, Shearwater, Apnealizer) and manual input for freedivers who want to enhance their footage with real-time dive data. Why I Built It: Adding dive data to videos manually is tedious. depthviz automates this by reading dive logs (.fit, .csv, .xml) from various sources, generating an overlay video with real-time depth, allowing full customization (fonts, colors, depth smoothing, stroke width), and running on Windows, macOS, and Linux. How It…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
