Automatic backup, no subscription required
When was the last time you backed up your phone? We thought so. (Here are six tricks for getting more out of your smartphone.) Check out MEEM, ($60) a charging cable that contains a back-up drive. Whenever you plug in your phone (iOs and Android) to charge, MEEM automatically backs up your phone. With the companion app, you can easily restore photos, videos, documents, and apps if your phone is lost or stolen—or you drop it in the lake (not again).
Spot the heat
With Flir One, ($199-$399), a thermal-imaging camera attachment for iOS and Android devices, you can find how the hot air is creeping into your house. Also good for DIY projects, camping, cooking, the Flir One is handy around the house, as well: Pinpoint water damage in floors, walls, ceilings, find sink clogs, and detect overloaded circuits. If you are trying to keep on top of home improvement, this can make life so much easier. (Here’s something fun: Cell phones have 40 years of pretty wild history!)
