Pricing

Buy the hardware once.

Optional subscription

OptiBreath Signal

The analysis layer. Twelve months are included with every Core and Pro, and the Founding Edition includes it for life.

€12per month, or €120 a year

Our commitment

The instrument is complete without it. Every sensor, the display, local history, alerts and the local API keep working forever whether or not you subscribe. Signal is the analysis layer, not a licence to use hardware you own.

Your CO₂ and cognitive-load timeline aligned against your calendar, so you can see which rooms cost you
Ventilation guidance tuned to your specific room's decay curve, not a generic threshold
Multi-year trends, seasonal comparison, and full-resolution CSV and Parquet export
Multi-device and multi-room roll-up for the home-and-office case
Anonymous benchmarking against comparable spaces

Still deciding between Core and Pro?

We wrote an honest answer to that on the FAQ. The short version: Core, unless you need the reading to stand up to a third party, want formaldehyde or radon specifically, or intend to pull raw data into your own stack.
