One clear action. Right when it matters.

HomeKit sensors and local weather become a simple answer: open, close, ventilate, run your equipment, or wait.

One clear action for the whole home, with room actions when they matter.

Coming SoonDesigned for iPhone and iPad, with Home Screen widgets and an Apple Watch companion.

Why it is different

Useful clarity, made simple.

The Klarhet idea

Raw signals in. Structured clarity out.

Klarhet Studio builds tools that reveal what matters and stay within what the source can support. Home Air combines real readings with transparent rules, so the same conditions always produce the same recommendation.

Deterministic decisions, built from transparent rules.

Private by design

Your home stays yours.

Sensor readings and decisions stay on your devices, with optional configuration sync through your private iCloud database.

Credentials stay in Keychain. Widgets receive a prepared snapshot.

How it works

Connect your home

Choose your HomeKit home, review its rooms and match the sensors and windows you already own.

Add outside context

Save your home's location and choose a weather source so opening a window is judged against conditions outside.

Act with confidence

See one house action and the room actions that matter most, with honest freshness and clear reasons.
