As someone who spends a lot of time outdoors (and someone who got hit with Lyme disease), it's astonishing how often I forget to apply insect repellent. Just the other night, I spent the last half of a five mile walk in a thick, annoying cloud of houseflies. Irritating, but at least they don't bite.
Not like horseflies... Now those things know how to bite! I've watch them land on my sleeve and start gnawing through the fabric. These things are vicious, the bites are super itchy, and scratching them increase the risk of them getting infected.

So, anything that can help heal insect bites is something I'm interested in testing. So, when I came across a product called Heat It, a smartphone-powered insect bite healer, my curiosity was piqued. It's not something I had ever heard of before, so imagine how interested I was when I discovered it's a tiny dongle that fits onto your keychain.
Here's how it works. First, you download the app to your phone (both iOS and Android versions are available), plug the dongle into your smartphone (there's a USB-C for Android and newer iPhones and a Lightning version for older iPhones), use the app to heat up the end of the dongle to a maximum of 124°F/51°C, then press the end onto the bite, and wait for the timer to say the treatment has completed.
