Heat It is a pocket-sized insect-bite treatment made by Heat It, presented as a smartphone-powered dongle designed to deliver controlled heat to bites, featuring a companion app and phone-mounted connectors. The gadget plugs into USB-C (or Lightning for older iPhones), warms to a maximum of 124°F/51°C and times each application via the app, with modes for adults, children and sensitive skin.

The device’s metal tip is pressed against the bite for the selected duration to reduce swelling and itch through targeted heat therapy. The dongle is small enough for a keychain, needs no charging and claims minimal battery draw from the phone. For outdoor enthusiasts, it offers quick, repeatable relief that beat topical creams in hands-on tests and reduces scratching-related irritation, making it a practical add-on to first-aid kits and trend-aligned wearable health tools.
