Comparison
TG Pro vs MacBookBatteryMonitor
TG Pro is a thermal and fan-control app. It reads battery temperature among dozens of other sensors. Here is how it compares with a dedicated battery tool.
What TG Pro does
TG Pro, by Tunabelly Software, is a thermal-management and fan-control utility. Its strength is breadth: it reads CPU temperatures per core on Apple Silicon, GPU and eGPU temperatures, SMART drive temperatures, logic board, trackpad, power, battery, WiFi chip, airflow, Thunderbolt ports, case, and memory sensors, and it logs the max temperature per sensor. Its fan control is full manual, max, and rule-based Auto Boost with custom curves keyed to any sensor. For battery it shows a Good, Fair, or Poor condition label, cycle count, and temperature, plus diagnostics for power supply and irregular shutdowns, with local and email alerts. It has the broadest platform reach in this list, running from macOS 10.13 High Sierra through macOS 26 Tahoe, on Intel Macs back to 2008, Apple Silicon, and even Hackintosh. Version 2.103 is current, and one $10 to $20 license covers three Macs. What it does not have is any power-draw monitoring or battery control. No per-app watts, no charge limiting, no Sailing Mode, and no process management. It is a thermal tool that happens to see the battery.
What MacBookBatteryMonitor does
MacBookBatteryMonitor is the inverse focus. It does not read system sensors or control fans. What it does is show real per-app power draw in watts, a component breakdown (CPU, GPU, RAM, display, USB), hidden drain from Docker, cloudflared, and launchd, a precise battery health percentage rather than a three-level label, and cycle count against the design limit. It adds the controls TG Pro lacks: a 50% to 100% charge limit over SMC, Sailing Mode, automated Low Power Mode, and per-app actions including a CPU throttle, an E-core offload toggle, and a one-click kill. It is Apple-Silicon-only on macOS 14.6 and up.

Which one should you pick?
TG Pro is the correct choice if your problem is heat or fan noise. It is the category leader for sensors and cooling, it covers far more hardware, and it is cheap. MacBookBatteryMonitor is the correct choice if your problem is battery life and longevity, and you need real per-app watts and charge control. Many power users will reasonably own both, because thermal and battery are different problems.
Frequently asked questions
Does TG Pro show per-app power draw?
No. TG Pro reads temperatures and controls fans. It has no process-level power attribution, no wattage readouts, and no battery control. For per-app watts you need a battery-focused tool.
Can TG Pro limit charging?
No. TG Pro has no charge limiting, no Sailing Mode, and no Low Power Mode automation. It is read-only on the battery, and only shows a coarse health label rather than a precise percentage.
Should I run TG Pro and MacBookBatteryMonitor together?
If you care about both thermal management and battery, yes. They cover non-overlapping ground. TG Pro for sensors and fans, MacBookBatteryMonitor for battery and power draw.
