Stern & Signal Labs is a small studio with one stubborn standard: build apps good enough that you'd never delete them. We make them for iPhone, Android, Mac — and even your TV.
Built in-house for iPhone, Android, Mac, and your TV — one's already out, the rest are landing soon.
Pregnancy brings a new question every day. BumpAI is the calm, always-there companion that answers them — week-by-week guidance, gentle reminders, and answers you can trust, minus the 2 a.m. internet spiral. Its AI runs privately, so your health data never leaves your control.
Most food logging dies by day three. NutriloggerAI keeps it alive: snap a photo or just describe your meal, and AI does the calorie-and-macro math — so you get the insight without the data entry.
Never be late to a meeting again. MeetingIntro lives in your Mac's menu bar, watches your calendar, and fires the right nudge before every call — a floating countdown, a voice reminder, one-click join. It can even auto-record your meetings and write the notes for you.
Reach anyone watching TV when you can't reach their phone. TV Messenger takes over the screen with a full-screen message — "dinner's ready" — reads it aloud through your TVs and speakers, and can even flip the TV to the right app right at kick-off.
No client work. No feature bloat. Just a handful of apps we obsess over until they feel obvious — the kind we'd want on our own home screens.
We'd rather ship two apps you love than ten you tolerate. Every screen, every word, every tap has to earn its place.
We use AI to remove work, not add novelty. If it doesn't make the app feel effortless, it doesn't ship.
Your data stays yours. No ads, no dark patterns, no selling your attention — just software that respects you.
We hit a problem we wish an app already solved — and get annoyed enough to fix it.
We shape the experience until it feels obvious, then cut everything that isn't.
We engineer the app and its AI in tight, hands-on loops.
We ship to both stores — then keep sharpening it for years.
New apps are landing across iPhone, Android, and TV. Drop your email and you'll know the moment each one ships — before anyone else.
