Best Bluetooth Multimeters for iPhone (2026)
As an Amazon Associate we earn from qualifying purchases.
Quick answer: A Bluetooth multimeter streams voltage, current, and resistance readings to your iPhone — easier to read in tight spots and lets you log measurements for diagnosing intermittent problems. Get a true-RMS pro meter for serious work, a clamp meter for current without breaking the circuit, or a compact pocket meter for everyday use. True-RMS, CAT safety rating, and the app's logging quality are what matter.

Pro tip — check the CAT safety rating, and use the logging mode to catch intermittent faults.
CAT (category) ratings indicate where a meter is safe to use (CAT III for fixed installation, CAT IV for utility-side measurements). Choose one rated for the highest-voltage location you'll measure. The killer feature of Bluetooth meters is data logging — set a long measurement and let it run to catch sporadic spikes or dropouts that a glance at the display would miss.
