The world’s first paper-based datalogger

Each Tapp label passively logs temperature and/or humidity at your chosen interval, with the alert rules you set. When your shipment arrives, the receiver taps the label with their smartphone to access the data report and instantly sees if action is needed, thanks to a clear green, yellow or red smiley. The data is then uploaded to the cloud, giving both sender and receiver full insight into what happened during transit.

Tapp is used by growers, exporters, transport companies, distribution centers and quality managers in floriculture, fresh produce, seafood, meat, pharmaceuticals and other temperature-sensitive goods. Anyone who wants reliable cold chain data with less waste and hassle.

Temperature labels measure temperature – Perfect for cold-chain shipments between -12°C and 50°C (10.4 °F to 122 °F)
Humidity labels measure temperature and humidity – For every cold-chain shipment between -12°C and 50°C (10.4 °F to 122 °F) that also relies on humidity data
Freeze labels measure temperature – Tailored for cold-chain shipments between -30°C and 35°C (–22 °F to 95 °F)

You need the app to set up your label with custom intervals and settings. To read the label, the receiver can use QuickTap with any modern smartphone: no app needed.

Each Tapp label shows clear smileys when tapped: green for good, yellow for moderate alert, red for critical alert. This way the receiver knows immediately if everything went well during transit — or if any action is needed.

Yes. Once the receiver taps the label, the data is uploaded to the cloud and instantly available to both sender and receiver in the dashboard. From both the app and dashboard, you can download and share label reports as pdf and share them with your team.

Yes! It’s a passive logger by design. Each label continuously measures temperature and/or hudity during the entire shipment, without needing a GPS connection or active data link while in transit. The data is safely stored in the label and instantly uploaded to the cloud when the receiver taps and reads it. So your shipment data is always captured, wherever it goes.

Tapp is designed leave less behind. Our label is made from sustainable virgin paper sourced from agricultural waste and contain no lithium, no heavy metals, and no plastic casing. 

Because our label is paper-based and ultra-light, it creates up to 90% less e-waste compared to conventional loggers. It’s optimized for minimal environmental impact, from production to disposal.

Looking ahead, we’re investing in next-generation manufacturing techniques to make shipment monitoring even cleaner in the future. Choosing Tapp means choosing a smarter, simpler and more sustainable way to track your shipments.
