Both are 4-probe WiFi leave-in thermometers. Both let you watch a brisket from your couch. One costs $70, the other $229. After running them side by side on the same cooks for half a year, here's what the extra $160 actually buys you — and who should pay it.
Quick Verdict
Buy the Inkbird IBBQ-4T ($70) for 90% of home cooks — it's accurate within 1-2°F, the app is reliable, and four probes is plenty. Buy the ThermoWorks Signals ($229) if you compete, run a side hustle, or simply want the most accurate and durable wireless probe system money can buy.

Accuracy
Winner: SignalsSignals is ±1.8°F across the range; Inkbird is ±2°F. In real cooks both track within 2°F of a Thermapen ONE reference. For brisket and pork shoulder the difference is invisible. For competition turn-in boxes where 5°F matters on a slice, Signals' calibration consistency over time pulls ahead.
Probe Quality & Durability
Winner: SignalsSignals' probes are Pro-Series — thicker cable, better strain relief, replaceable individually for $20. Inkbird's probes work great out of the box but the cables fail at the connector after 12-18 months of regular use. Replacement Inkbird probes are cheap ($25 for four) but you'll buy them more often.
App & WiFi Reliability
Winner: SignalsSignals connects to ThermoWorks Cloud which is rock-solid — never drops, alerts always fire. Inkbird's app is functional but occasionally loses connection in cold weather or when the phone backgrounds it for hours. Both have local WiFi (not Bluetooth-dependent), which beats Bluetooth-only competitors like FireBoard's cheaper models.
Display & Standalone Use
Winner: SignalsSignals has a bright, readable display you can use without a phone — set high/low alarms with physical buttons. Inkbird has a smaller display and clunkier button navigation. If you cook without your phone nearby, Signals is the obvious choice. If you're glued to the app anyway, neither display matters.
Value
Winner: InkbirdInkbird wins on pure dollars. $70 for accurate 4-probe WiFi monitoring is incredible. Signals at $229 is 3.3x the price for marginally better accuracy and meaningfully better build quality. For most backyard cooks the Inkbird math wins; for someone who'll use it 200 cooks a year, Signals' durability earns it back.
Final Verdict
Inkbird IBBQ-4T wins for nearly every home cook. Signals wins for the small minority who cook constantly, compete, or want pro-grade gear they'll keep for a decade. Both are excellent at what they do.
Buying Advice
Start with the [Inkbird IBBQ-4T](/review/inkbird-ibbq-4t) — at $70 you're not over-committing, and if you outgrow it in three years the Signals will still be there. Pair either with a [Thermapen ONE](/review/thermapen-one) for spot-checking — the combo of leave-in probes and instant-read covers every cooking scenario.
