Available on iOS and Android. Hold your phone against any Tempest or Yotta sensor — the reading is in your hand in under a second.
In the meantime, any NFC-capable phone can read your sensor data right now — just tap your phone to the sensor.
No account. No subscription. No cloud. All data stays on your device.
Touch your phone to any Tempest or Yotta sensor and read temperature, humidity, irradiance, and exposure totals in under a second — offline, no pairing.
Organise readings into named groups — a shipment, a grow room, a site — with all history stored locally on your device.
Export any reading or group as a CSV or a formatted PDF for audits, compliance records, and handovers.
Add a location label or floor-plan overlay to map multiple sensors across a facility, cold chain, or field site.
Send a group or reading straight to a colleague's phone over a local peer-to-peer transfer — no internet required.
No account, no data collection, nothing sent off your device. See our privacy policy for details.
