Building https://check.supply : the easiest way to mail a real paper check from your iPhone. Link your bank, type the amount, and we print + mail it for you — with optional certified or express USPS tracking

Major US banking apps I've used in the past 7 or so years already support mailing physical checks directly from their mobile apps via their bill pay service. Just add someone's physical address as a "payee", create a payment, and it sends them a check in the mail, for free. Perhaps your app is slightly more convenient and has more advanced features which make it worth the fee, but it seems like a problem already mostly solved and widely available.

Defect detectives - The giga yield case files. My PTG spots 99.9% of giga flaws - Solve a case, win $25k or a live NFT dashboard pass. Each week, a "crime scene" dataset is dropped from a simulated Tesla Giga factory line, Data is 95% sparse, mimicking real-world sensor noise and incomplete logs. Players must detect "defects" ( e.g., micro-anode cracks,electrode delamination, thermal hotspot anomalies) Gameplay loop is simple 1. Players join via X threads or 'n "case assigned. 2. Download Giga dataset fragment ( Structural CSV/API feed) 3. Runs analysis with PTG ( Probablistic Tesla Graph) or custom script 4. Submit predicted flaw coordinates.

I got tired of trying to find a good MP3 player that just worked so I created a website to function as an online MP3 player. I started adding sources for content and ended up supporting YouTube, Spotify, Twitch, Instagram, Vimeo, SoundCloud, Rumble, WSHH, Facebook and X. So now you can create playlists from all of those sources with features you would find on any decent MP3 player such as loop, repeat, etc. I also dr…

Just scratching the surface, but this looks really cool! Thank you for sharing this. Sort of thing that should exist. Digging the development methodology too.

AI assisted boardgame design process. I enjoy exploring AI-assisted process development. Things I've learned are: * Building nôn pipelines for generating placeholder art. GPT-5 excels at writing code nodes. * LLM for LaTeX generation (note: GPT-5 generally fails at even moderately complex LaTeX and often adds complexity while endlessly orbiting the problem without solving it. On of the other hand, it's failed solutio…

Never heard of "nôn pipelines" - is that like a new thing?

Working on my website that can heatmap cities based on your lifestyle preferences. https://theretowhere.com It currently supports complex heatmaps based on travel time (e.g. close to work + close to friends + far from police precincts), and has a browser extension to display your heatmap over popular listing sites like Zillow. I'm thinking of making it into an API to allow websites to integrate with it directly.

Absolutely stellar! I've been looking for something like this for ages. Any chance you'll have some pre- defined options like grocery stores, libraries, airport, etc?

Yup! Definitely something I've been thinking about

I’m working on a free and open-source invoice generator: https://easyinvoicepdf.com/?template=stripe - No sign-up, works entirely in-browser - Live PDF preview + instant download - VAT EU support - Shareable invoice links - Multi-language (10+) & multi-currency - Multiple templates (incl. Stripe-style) - Mobile-friendly GitHub: https://github.com/VladSez/easy-invoice-pdf Would love feedback, contributions, or ideas f…

Something worth considering: the e-Rechnung directive enforcing b2b invoices with standardised metadata. They're becoming mandatory in Germany and I think they already are in some other EU countries.

I'm a dev and also a private pilot. Currently I'm working on Pilot Kit: https://air.club/ , a mobile app born from my own frustration with the amount of tedious paperwork in aviation. It's an all-in-one toolkit designed to automate the boring stuff so you can focus on flying. Core features include: automatic flight tracking that turns into a digital logbook entry, a full suite of E6B/conversion calculators, customiza…

Very cool, thanks for sharing!

thanks!

Yep, thanks for the heads-up. It’s already planned: https://github.com/VladSez/easy-invoice-pdf/issues/121

Month 48 of my one-man project Zigpoll: https://www.zigpoll.com/ On-site surveys for eCommerce and SaaS. It's been an amazing ride leveling up back and forth between product, design, and marketing. Marketing is way more involved than most people on this site realize...

48 months solo is impressive. That marketing line is 100% true.

I'm building a tool that auto-generates ad creatives from a url (img-pt.com). Happy to run it on zigpoll.com and show you what it comes up with, if you think it can help you out.

Thanks for sharing these tips — especially the mention of PlasticScore and independent lab testing. I’m working on a project that helps people make smarter financial and lifestyle decisions, and I’ve noticed how small choices (like packaging or product sourcing) can have long-term health and cost impacts.

Curious: have you come across any tools that combine environmental impact with financial planning? I’m exploring ways to make calculators more holistic — factoring in not just money, but sustainability too.
