IamThermowatt allows you to find out if the thermostats and the heating elements are original, just holding your smartphone on the NFC logo printed on the carton box. NFC is a microchip device and the most innovative technological solution that replaces other easily reproducible solutions such as QR-codes or holograms. The unique βembeddedβ NFC tags are applied directly on the boxes, equipped with a serial number (which cannot be reproduced and cannot be falsified) and can be easily read by wholesalers and by their retailers through smartphone where IamThermowatt is installed. Fight the counterfeiting with Thermowatt!

Verdict
The clearest difference is in-app purchases: IamThermowatt at none against OKTap's 1. IamThermowatt also leads on iOS requirement (15.0 vs 17.0). OKTap's advantage is update cadence (every 5 months vs every 15 months). On price, ads and device support there is nothing between them.
