Show HN: I built a tool to solve window management
Hello, my name is Andrew. I'm an indie developer and I'm excited to release Smart Switcher for Windows 10/11. I'm looking for feedback on the overall project and the application itself.<p>I built this because I couldn't find a window switching/management solution that worked for me.
I tried all kinds of different solutions, virtual desktop extensions, obscure GUI window managers, you name it.
Overtime I realized I wanted something that prioritizes one window at a time, is keyboard driven with has minimal if no GUI elements.
I figured this part out, but knew something was missing.
I had my eureka moment when I realized I could combine my switching method with a prediction algorithm. This led to the creation of Smart Switcher.<p>Smart Switcher is a data driven window switcher aimed at improving the overall window switching experience.
It logs data on your windows switching, then a prediction algorithm analyzes this data and uses it to predict which window you would want to switch to next.
When you need to switch windows, you press the switch shortcut to switch to the next predicted window.
If this isn't the window you wanted, press the override shortcut to switch to the next most likely window.
You can press the override shortcut as many times as needed until you arrive at your desired window.<p>It’s a paid app with a demo and trial version.
There is a introductory discount and some additional discount tiers for early adopters.<p>Any feedback is appreciated! Thanks!

Show HN: A rain Pomodoro with brown noise, ASMR, and Middle Eastern music
I built this because most Pomodoro timers felt too sterile.<p>I wanted something that actually pulls you in with rain, brown noise, soft ASMR, and a few Middle Eastern tracks. Added animated backgrounds so it’s not just a blank screen.<p>Runs fully in your browser. No accounts, no tracking, just open it and focus.<p>If you give it a try or have ideas to make it better, I’d love to hear.

Hey HN,<p>I built Jukebox because I got frustrated with group music apps and Spotify’s limitations (not everyone has Spotify, and collaborative playlists are still too easily dominated by one person).

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.

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!
