超コーヒー · Emergency caffeine mode

There once was a builder named Saar,
a midnight-to-dawn coding star!
When Shablam goes BLAM!
and Milat shouts “ciao, fam!”—
one coffee sends him SUPER far!

Shablam!

Shazam for Drag Race

Ever listened to a song and wasn't sure if it was on Drag Race? Shablam! identifies any song used in a Drag Race lip sync using ShazamKit, reveals who won, lost, and sashayed away, provides season, episode, and franchise details, and offers links to stream the songs on Apple Music.

tMinus

Star the stops you use, and tMinus tells you when to leave

An open-source MBTA companion for Android. Star the stops you use and they become live departure boards on Home, home-screen widgets, and notifications that tell you when to leave for a commute, when the last train goes, and when an elevator at your station is out. No account, no onboarding, and it works without an API key. Built with Jetpack Compose and Glance against the public MBTA V3 API; the source is on GitHub for anyone who wants to build on or learn from it.

Milat

One word a day — Hebrew and Italian

Milat (מילת היום — “word of the day”) shows a single curated word each day in Hebrew and Italian. Hebrew entries include nikud. The app stays intentionally minimal: one screen for the daily pair, no quizzes or flashcards. Home screen widgets are available in several sizes so the word is visible without opening the app. Hebrew words are hand-curated toward practical, conversational vocabulary you might not see in a typical classroom or ulpan track; Italian words are AI-assisted.

Eurovizam

Whence

Where that song was on screen

A Flutter app that identifies any song with ShazamKit, normalizes metadata with MusicBrainz, enriches results with TMDb (and OMDb as fallback), and caches matches locally for fast repeat lookups — so you can discover where a track appeared in TV and film. Available on iOS, iPadOS, macOS, and Android (Android 12+).

Obi

Follow along with your records, on your TV

Put a record on and Obi tells you what's playing. Drop the needle, press OK, and it listens to the room, works out which record is on the turntable, and follows along for the rest of the side — lyrics in time with the music, the tracklist, and how long you have before you need to get up. No account, no library to build, nothing to import. Obi doesn't play the music; your turntable does that.

Lexeme

Tap. Guess. Read your books. — lexeme.uk

In progress

Most people learning a language own a book in it they never finished — usually abandoned in the first thirty pages, because looking up the fourth unknown word on a page costs more than the sentence is worth. Lexeme is my attempt to make that cost close to nothing and then get out of the way, because the book was always the point. It's a calm EPUB and PDF reader for people who learn by reading real books: tap any word for an offline meaning with the conjugation resolved, and it quizzes you before it answers. The lookup is the whole product, so it runs in four steps and three of them work in airplane mode: direct hit in the installed dictionary, then lemmatisation, then form-of resolution through the inflection table — andiamo walks back to andare, accents folded so vado and dissi resolve too — and only if all three miss does it ask the network. The Italian hero pack is 651,002 headwords in 147 MB, built from Wiktionary via kaikki.org plus FreeDict, downloaded on request and verified against a SHA-512 in the catalogue. Twenty-odd other languages get basic offline glosses from FreeDict. Turn on Learn mode and a tap opens a question instead of an answer: four options, one right, three drawn from genuine dictionary meanings that share the tapped word's part of speech — so "to consume" and "to feed" sit next to "to eat" and you actually have to think. Words you save keep the sentence you met them in and the lemma behind them, and export to Anki or CSV. Books come from your own files or from a Project Gutenberg search inside the app; attach an audiobook and the text follows the narration. No account, no analytics, no server holding your library. It's a personal project, built for one reader to finish Italian novels with, and it has never been released — lexeme.uk is a description of what it does, written against the code.
