SparkFun offers the Mooshimeter, a multi-channel multimeter that displays data on smartphone or tablet using Bluetooth® 4.0. The Mooshimeter safely measures voltage, current, resistance, and temperature from up to 50 meters away with 24-bit ADC precision. It can measure any two of its three inputs at once, and log the data to an SD card for up to six months. All you need to do is set up the sample rate on the iOS or Android app. The Mooshimeter also comes with an accessory kit, which includes two AA batteries, three 10 A 600 V CATIII test leads, three slide-on alligator clips, and a protective carrying case.
