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. -…
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.

In the maker’s words, at launch
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. - I mean very ugly. So I spent the last months building my own from scratch. Cool fact: the most famous platforms for divers on the web actually have pretty naive algorithms for computing consumption. Therefore I worked with my brother (PhD in Aerospace Engineering and Fluid dynamics) to devise a very accurate - probably the most precise among existing apps - model for computing true mixture consumption, which actually is a fundamental parameter to keep under control when diving. I think we will write a blog about it. I do not know if there is any dude here on HN that is both a tech nerd and scuba diver, but hey, if you do exist, I would love some feedback. Cheers! Matteo

Please check it out. I spent all of 2012 learning to code to launch what would eventually become Uncover. I'm super excited to announce that we're finally live. Here's a blog post I wrote on how we got there and a little story behind the startup: http://spencerfry.com/introducing-uncover
- FOFinally opening signup on my education for business startup, Learndot2013 · ▲55
HN, I've been mostly lurking, semi-active on HN for over 4 years. For most of that time, I've been working on my startup, Learndot. I have always wanted to do a "Show HN" post, but I never thought it was ready. We've now finally launched web signup and using a freemium business model. I feel I can now post and offer something to the community (a new app to try out) and hopefully get good quality feedback. Here's the site: http://www.learndot.com Would appreciate any or all thoughts: From pricing/positioning, to design/performance. The app is written in Sproutcore and backed by an API written…
- SLsoft-launching one of my pet projects2011 · ▲27
So a while ago I was thinking it would be neat to build a site that had the most absolute utility. The idea I came up with was a site to store those little protips that are super useful, if you know them ahead of time. I hired a guy to work on it with me, and ClueDB was born: http://cluedb.com/ Please give it a whirl (it uses Twitter auth as login but doesn't tweet anything) and tell me what you think! (Various trivia: My first try at a project coded by someone else and "product managed" by me. Runs on Flask + MongoDB. Also, this is totally unrelated to my startup.)
- IMI'm a non-hacker "idea guy" and my weekend project took 1,670 + days2012 · ▲21
I am a non-hacker "idea guy" with zero discernible talent. Like most, the story starts with me doing things the hard way. I dreamt of a tool that would save me countless hours. Like most of my ideas, it was supposed to die in a couple of hours, but this one had some legs.... "If I needed this, surely others did too" kept looping in my head. Could I get this built? Could I build it myself? Nah...too lazy to learn how, but before I did anything, I had to promise myself one thing: No more ideas! If ideas were sit-ups, I would have a six pack instead of this tire. It was a constant mental…
- ACA Cryptic Hunt Website2021 · ▲17
Hi HN!, We're a group of High Schooler's who have made a website for an international cryptic hunt we have been organizing. Everything has been built from the ground up and has been open sourced. We'd love feedback on our work. And if it interests you, feel free to register and try a level or two! URL: https://halocrypt.com/ Source: https://github.com/halocrypt We're particularly proud of our frontend, since we have used a framework we built ourselves!
