Reclaim
Find what is actually taking your disk space on a Mac.
Reclaim is a free macOS app that finds reclaimable disk space and removes only what you tick. It is built for developers: it measures the caches other cleaners miss — Xcode archives and DerivedData, iOS simulators, node_modules, Gradle, Homebrew, Docker images and downloaded AI model weights — and explains what each item is before you decide. Scanning is always free and unlimited, and so is clearing anything it classes safe.

Gossip Buzz
Private messaging and a social feed in one app.
Gossip Buzz combines end-to-end encrypted messaging with a social feed of short posts, moments and communities. Messages are encrypted on your device before they are sent, so the server stores ciphertext it cannot read. It runs on iOS, Android and the web, in eleven languages.

Ekkul
Exam preparation that adapts to what you keep getting wrong.
Ekkul is an online learning platform for exam preparation. Students practise against question banks for tests like the DMV written exam, GED and real-estate licensing, sit timed model tests, and see which topics they are actually weak in. Instructors and institutions get their own portals for setting work and following progress, and parents can follow a child's learning without sitting over their shoulder.

Ekkul Jr
Learning for ages 2 to 16, built to work offline.
Ekkul Jr is the younger end of Ekkul, designed for ages 2 to 16 and organised into age tiers so a four-year-old and a fourteen-year-old do not get the same screen. It is offline-first on mobile, because the children who most need it have the least reliable connections.

OnAir
Live television and creator streaming, in one place.
OnAir is a streaming platform for live channels and creator broadcasts, on the web, on iPhone and Android, and as a desktop app for macOS, Windows and Linux. Viewers watch live TV and follow creators; creators publish their own shows and streams and are paid directly, with the split shown openly rather than buried in terms.

Halo Keyboard
A keyboard that helps you write and never records what you type.
Halo Keyboard replaces your phone keyboard and can rewrite, shorten, translate or fix the tone of what you are typing, wherever you are typing it. It works with no account. There is deliberately nowhere in its design to store the words you type — a keyboard that shipped what people typed would be a keylogger, so the storage for it simply does not exist.

Halo AI
An AI assistant that works without an account.
Halo AI is a standalone assistant for phone and Mac. It answers, drafts and translates, and it starts working the moment you open it — no sign-up, no email, no profile. Linking a Gossip account is optional and only adds online voice typing and credits.

Halo Study
Study from your own material, offline.
Halo Study turns notes, textbooks and photographed pages into practice material that works with no connection. It is deliberately extractive rather than generative: questions come from your material, so it does not invent facts a student would then revise.
