Web App Tools

A calm, local-first writing app with deep focus, ambient sounds, optional cloud sync, and PDF export.

Make a room, share a code, and everyone plays on their own phone. Secret votes, live results, no app and no sign-up to play. The Party Starter deck is free; extra packs are a one-time unlock. Plus Omi, the classic Sri Lankan card game.

Poddle is Wii Sports-style pickleball for your browser, played only with the devices you already own. Open poddleball.com on any computer, scan the QR code, and your phone becomes the paddle. On a Mac, one AirPod can be the paddle instead; a small open-source helper app streams its motion sensors to the game, and the other AirPod stays in the case. Play a friend online, take on Matt the bot at four difficulty levels, or run a tournament, and earn trophies as you go. 100% fun and free to play!

Dictoterix is the first online learning service built end-to-end around the bilingual-dichotic method: your native language in one ear, the language you're learning in the other, at the same moment. Most apps teach “words”. The question that matters is which words — so every level in Dictoterix is measured against a reference inventory of what an A1–C1 learner actually needs. No card. No trial clock. It's just free.

Simha is an SEO workspace that tells you what to fix, not just what's wrong. Connect Search Console and Analytics, run a crawl — and get one health score, a plan ordered by traffic at stake, and an AI summary of what changed and why. Then the part no other tool has: we ask AI search engines your key queries and show whether ChatGPT-style answers cite your site, and who gets cited instead. Growth points, Core Web Vitals, an assistant that knows your data. 7 days free.

StillTalk turns one generated photo into a character that talks. Your device draws every frame live in the browser; the server sends only speech and compact movement data. Five characters, six languages, or type your own sentence. No signup. Engine built with GPT-6 Astra.

I built Folio because I kept getting distracted by notifications when trying to read on my phone. Folio takes your open tabs, RSS feeds, and newsletters, and turns them into a cleanly typeset digest. You get a private email address for newsletters, and it strips out the ads and menus. Then it automatically delivers a custom PDF or EPUB directly to your reMarkable, Kindle, or Google Drive. The idea is to move your reading to an e-ink device, so you can actually focus.

nOS4 brings the iPhone you remember back to your browser. Play around, open some apps, play games and enjoy the nostalgia :)

RIP MY BUILD is a side project cemetery for honest public postmortems. Publish a permanent obituary with the original link, cause of death, lesson learned, and whatever you’re building next. Every memorial gets a shareable page, visitor roses, permanent plot adornments, and a weekly honors leaderboard. It turns the useful truth at the end of a project into closure, a launch asset, and a path to the founder’s next chapter. $12 per obituary; no account needed to browse.

Look beyond the vendor name. Understand MAC addresses with IEEE block data, device-category clues, privacy-randomization signals and plain-English reasoning. Use it through the free lookup, JSON API, bulk databases, log extractor, MCP or self-hosted deployment.

Turn your images into seamlessly looping case study and portfolio videos, right in the browser. Pick a template, tune the motion live, export up to 4K. Every export loops perfectly, no keyframes, no After Effects. Free plan exports real files, no trial wall

An animated pixel-art map of the solar system with every body at its real current position, computed from published orbital elements rather than copied from a list. Zoom from the Sun to the Kuiper belt, browse 171 catalogued objects with sourced facts, and see what the sky is doing for the next six months. Every rock is also for sale: claim an asteroid for $5, keep it forever, name it whatever you like. A name here is shown on AstraPixels only, and is not an IAU designation.

The Garden of Mind is a visualisation of your subconscious mind. Whatever you hold in your attention gets planted in you — so plant one thing on purpose. Write an intention and it becomes a seed in a living 3D garden. Water it two minutes a day: read it, breathe with it, picture it as already true. The plant grows across real calendar days, so what you see is what you kept choosing. Free to start, no account, nothing to install. Founders Pro is €29 once — nothing renews, ever.

Yamanote 3D is a free browser experience inspired by Tokyo’s Yamanote Line. Walk through an E235 carriage, sit down, watch the city, listen to announcements, and get off at stations.
