MeetingIntro

macOS 14+ · Menu bar

Available now

Never miss a meeting's start — right from your Mac's menu bar.

A macOS menu-bar app that watches your calendar and fires the right nudge before every meeting — a floating countdown, a notification, or a spoken reminder — then quietly handles the rest: auto-join, recording, and AI notes. For professionals who live in back-to-back calls and want to stop tabbing to their calendar.

What it does

›

Countdown reminders — floating overlay, notification, and/or voice, per threshold.

›

Start-at-Time auto-join — opens the conference link the moment a meeting begins.

›

Context-aware — stays silent when you're on a call, in Focus, sharing, or fullscreen.

›

RSVP-aware — declined or unanswered invites never interrupt you.

›

Auto-record + AI notes — dual-track audio → transcript → AI meeting notes.

›

Quick Add — "lunch with Sam tomorrow 1pm" becomes a calendar event.

›

Calendar mirror — one-way sync into a shareable availability calendar.

›

Dual backends — local calendars via EventKit + Microsoft 365 via Graph.

Why it's different

Not just a reminder — a context-aware meeting concierge that knows when to stay quiet (real mic-in-call detection, not "is Zoom open"), auto-joins on time, and hands you a transcribed, AI-noted record — all from a lightweight menu-bar app.

NutriloggerAI

iOS 17+ · iPhone

In App Store review

Stop counting. Start chatting — AI nutrition tracking with personality.

A native iOS nutrition tracker that swaps tedious food-database searches for natural-language chat and photo logging. It pairs calorie and macro tracking with a "Nutrition Squad" of AI coaches and condition-aware health scoring — for everyday people managing weight, fitness, or a chronic condition who find calorie counters a chore.

What it does

›

Food Snap — photograph a meal; AI identifies it and estimates nutrition.

›

Chat logging — "I had 2 eggs and toast" logged instantly, no database digging.

›

Barcode & search — 500k+ barcodes, backed by the USDA food database.

›

Nutrition Squad — 8 AI coaches with distinct personalities and memory of your goals.

›

Daily Health Score — a 0–100 score tuned to your conditions, not a generic number.

›

Full macro & micro — calories, protein, carbs, fat, fiber, sodium, sugar, and more.

›

Monthly AI reports — insights on what's working and what isn't.

›

HealthKit — pulls energy and steps from Apple Health / Apple Watch.

Why it's different

The only tracker combining conversational + photo AI logging with condition-specific health scoring and a squad of memory-equipped personality coaches — turning calorie counting into a chat with someone who remembers your journey.

BumpAI

Android · iOS planned

In development

Your private, AI-powered companion for every week of pregnancy.

A pregnancy companion that pairs week-by-week guidance with real health tracking and an AI chat assistant that actually knows your data — daily briefings, symptom and nutrition logging, appointments, and proactive health alerts. Built for expectant parents who want personalised, proactive care.

What it does

›

Week-by-week dashboard — gestational tracking, daily briefings, fetal-development guides.

›

AI chat companion — pregnancy Q&A that draws on your own logged health data.

›

Smart nutrition logging — free-text meals parsed by AI, with ACOG-based targets.

›

Health tracking — BP, glucose, heart rate, symptoms with 7/14/30-day trends.

›

Wearable sync — steps, weight, and heart rate via Health Connect / Oura.

›

Proactive alerts — rule-based checks and a daily tip, with quiet hours.

›

Appointments — scheduling, AI visit summaries, and ultrasound uploads.

›

Partner linking — share the journey and store key medical info.

Why it's different

Unlike cloud pregnancy apps, BumpAI runs its entire AI stack on a self-hosted local model — ultrasound images, food logs, and health metrics are processed on-network and never sent to a third-party AI provider. Private by architecture, not just by policy.

Platform: Android (Kotlin + Compose) Status: in active development (v1.3.0) Privacy: self-hosted local AI · health data stays on your network

TV Messenger

Android TV · Google TV · self-hosted

Shipping · self-hosted

Message any TV in your home — it takes over the screen.

A self-hosted home messaging and event system for Android TV households. From a phone app or a zero-install web page, push a message that interrupts whatever's playing and shows a full-screen takeover on any TV — then auto-dismisses. It's grown into a family intercom and event assistant for TVs and smart speakers.

What it does

›

Full-screen takeover — a message interrupts Netflix, live TV, anything — unmissably.

›

Text-to-speech — read aloud on the TV and spoken on Google/Nest speakers.

›

Photos & voice notes — send a picture or a recorded clip, not just text.

›

Any room or all — target one TV, one speaker, or blast the whole house.

›

Scheduled sends & countdowns — queue for later, or a ticking "Leaving in 10:00".

›

Event reminders + tune-in — auto-launch the right app at kick-off for a game.

›

ICS calendar import — pull fixtures from a feed and turn them into reminders.

›

Two senders — a native phone app plus a zero-install web app from your hub.

Why it's different

It uses a full-screen takeover rather than a floating overlay — because premium video renders on a secure surface that blanks overlays. The takeover reliably pauses the app behind it on stock, unrooted hardware. Everything runs on your own local network through a self-hosted hub — no cloud.
