bluTag is the iPhone app for Blulog NFC temperature and humidity data loggers. Hold the phone against a logger to read it, program a recording, and send the measurements to BluConsole.

What you can do • Read a logger over NFC • Start, restart and stop a recording • Program one logger or a series of loggers with the same settings • Review temperature, humidity and probe channels, including threshold breaches and charts • See where the logger was read, on a map • Save programming profiles: measurement period, end date and temperature limits • Download a PDF measurement report and the logger calibration certificate • Share results as PDF, CSV or XLSX, and open them from the Files app • Upload measurements to BluConsole, and retry automatically if the network drops • Keep a local audit trail of scans and writes, then send pending logs to BluConsole • Run a technical NFC reading that sends the full memory to BluConsole for analysis • Use the app in English, French or Polish • Set the temperature unit and your BluConsole account
