Show HN: OffChess – Offline chess puzzles app
Hi HN!<p>I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet.<p>Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess.<p>OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1/2/3/4/5, tactics like pins/forks/skewers, or openings like Sicilian/French, etc). You gain or lose points based on how you perform, so there's a light rating system to keep things engaging.<p>No accounts, no tracking, no monthly subscriptions, no internet required. Just pure, old-school tactical chess training, wherever you are.<p>You can check out the iPhone/iPad app at <a href="https://apps.apple.com/us/app/chess-puzzles-offchess/id6744736661?platform=iphone">https://apps.apple.com/us/app/chess-puzzles-offchess/id67447...</a> or the Android app at <a href="https://play.google.com/store/apps/details?id=com.offchess">https://play.google.com/store/apps/details?id=com.offchess</a><p>Would love feedback, bug reports, or suggestions.<p>Thanks!

Show HN: From Photos to Positions: Prototyping VLM-Based Indoor Maps
Just a fun hack I did while bored over the weekend. My wife was busy shopping, it got me thinking that can VLMs solve the indoor location problem in a mall? Can I just show a VLM a map and an image and have it doa good enough job locating me? I hacked this P.O.C and it seems to work.

Show HN: I Got Tired of Calculator Sites, So I Built My Own
I’ve always found that online calculators tend to have bad UIs, especially on mobile. Most of the calculator websites I’ve come across use outdated and inconvenient ways of inputting data, or they format the results in confusing ways.<p>I’ve noticed that fraction calculators (especially mixed fractions) are terrible to use, even on desktop. I haven’t built one of those yet, but it’s something I’m planning to tackle soon.<p>This is a project I’ve always wanted to work on, but I’m relatively new to this space. So far, I’ve created a collection of simple calculators focused on math and finance.<p>I’d really appreciate any feedback on the UI/UX or anything else you think could be improved.<p>You can try it here: <a href="https://CalculateHow.com" rel="nofollow">https://CalculateHow.com</a>

Show HN: NYC Subway Simulator and Route Designer
Hello HN!<p>As a long term NYC resident, I have read countless articles on ideas tweaking subway services, but always found them hard to follow without visual aid. So over the long weekend I decided to build one. It has all the basic features: trains would spawn at their origin, stop at stations, and slow down if it gets too close to another. You can also design custom routes by piecing tracks together.<p>Have fun, and let me know what you think!

Show HN: Pixel Art Generator Using Genetic Algorithm
This project is a simple but fun demonstration of a genetic algorithm applied to image generation. It starts with a population of random images and evolves them over generations to resemble a target image. The output is an animated GIF that shows the entire evolution process.
Show HN: a community for collaborating on sideprojects
TLDR: I made a community where you can find builders or product owners to collab on sideprojects together with <3<p>A year ago i completed my first sideproject, a digital course on how to "cold email a chief information security officer". I thought and think its a great course, but of course I fell into all the traps (didnt verify a need, i thought id make it and everyone would buy automatically), i tested google ads but hated nerding on that, so i decided to find a marketing person to partner up with! But i knew no one! That got me thinking how many people with relevant knowledge that isnt connected to others who need it, so i started gathering these people in an excel doc with what they know and then we created a slack channel for this etc! (fenomener.framer.website). Suddenly now we are 400 people sharing about our projects and collaborating! But if there is one thing ive been missing its "profile pages", that doesnt work well in slack. Id love to see an awesome project but then lurk a bit on who this person is before engaging in anything. so thats when we made the common decision of: what the heck, lets just build the thing we want.<p>So I partnered up with a fullstack (from the community!!!!!) and built relentlessly.no. we have like 50 users now and 17 projects and just finished our Minimum Lovable Product. Its not good enough yet and we are working on adding notifications and at least optimizing for first the product leader flow, then the builder flow. (we often get product leaders with a demo joining that are HUNGRY for devs, or we get builders hungry for anyone with an idea! its a god damn marketplace maybe!)<p>I actually think this might become 1000x more important than YC, because its place and time independant, and no one or no org has taken a place in the important space of sideprojects, where actually "everything begins". SIdeprojects sound so naive and not important, but after nerding on this a year i kinda see them as the most powerful thing we have. And this feels exactly as counter intuitive as a great idea should feel. So if we can let relentlessly resourceful people around the globe bump into each other, then the next gen of startups will be born here. Thats freaking meaningful stuff. And the hidden gem in all of this is something that didnt strike me before i had been working on it for a year: The point isnt to find someone to collab on your current sideproject. The whole value is the relationships that get formed. Because now after a year in this space then sideprojects have come and gone, but i have like 8 new "cofounder ready" relationships formed, where i actually trust them and "know" them and can build in the future with them. So i guess we are sortof solving "cofounder matching" without the akward "cofounder meetup night", or the slow "you HAVE to go to school with them for four years.<p>business wise this is my passion project for life I feel, and the ethical founder friendly direction im pursuing is just adding this on the site: "if you met your cofounder here, like the product and youre raising money with another confirmed investor: please invite me to your round <3"<p>I dont have money but maybe that will sort itself out, so this just makes me the worlds poorest investor with the most original investment product ever :D
