This app is aimed at interested users and testers who want to test the performance of the integrated CPUs. For this purpose, it offers a mixed test for single-core and multi-core CPUs, as they also occur in real life. In the single core test, the app calculates ten million random numbers from a total of six different data types (Int, Float, etc.). Such calculations are crucial for game apps. APSI Bench then calculates one million FFT transformations that are common in audio applications, for example. In addition to this, the app also runs a ray tracing algorithm that uses several CPU cores at the same time. You can set how many cores should be used here. The results of these tests are based on a reference system (currently a Macbook Pro 16 inch with an eight-core Intel i9 CPU). That reaches about 100 points. Every user of the app can test the ratio of their Apple product to the MacBook Pro. A decisive extension is the newly built in long-term measurement. Here the app carries out the ray tracing tests with all available CPUs over a long period of time that can be set by the user (up to 30 minutes). The result is then displayed in graphic form. If problems arise with overheating of the CPU cores, this will be visible in the graphic. Finally, the app is also a technology demonstration. The entire interface was designed in SwiftUI 2, with gorgeous animations being used. The app will also be offered as a universal app for macOS.

Evaluate your device's stability under sustained workloads, monitor thermal regulation safely, and see how you rank on the global leaderboard with ThermoHammer. Designed as a diagnostic tool for power users, developers, and hardware enthusiasts, ThermoHammer safely analyzes how your device manages processing efficiency under standard, continuous multi-threaded tasks. It helps you understand your hardware's capabilities, thermal dissipation, and peak vs. sustained performance over time. Do you experience frame drops during intensive tasks or long productivity sessions? ThermoHammer visualizes exactly how your device’s operating system manages efficiency to maintain optimal hardware health. ### KEY FEATURES: - **Real-Time Efficiency Graph:** Watch your device's performance curve in real-time. See clearly how the system dynamically regulates its processing power to manage heat. - **Global Comparison Leaderboard:** Submit your benchmarking scores and compare your device’s sustained performance (GIPS) against other users worldwide. Check how your specific model ranks in the global database. - **Accurate GIPS Tracking:** Track performance in GIPS (Giga Instructions Per Second) to capture objective, high-precision performance metrics. - **Three Standard Test Intervals:** Run structured, highly controlled tests of 5, 15, or 30 minutes to observe performance behavior over short, medium, and long durations. - **Thermal Design Evaluation:** See how different environmental temperatures or protective cases impact your device's natural heat dissipation. - **Clean, Data-Focused UI:** Minimalist and non-intrusive. Get straight to the diagnostics with clear, readable data visualization. ### SAFE & SYSTEM-COMPLIANT BENCHMARKING: ThermoHammer is engineered with hardware safety as our top priority. The app acts as a standard diagnostic utility, running standard arithmetic calculations completely within the operating system's built-in thermal and power-management safeguards. ThermoHammer does not bypass system limits, modify hardware settings, or override core safety parameters. It simply measures how the device's native thermal throttling protects the hardware during normal, sustained computational tasks. A stable, flat graph indicates highly efficient thermal design, while a gradual curve shows the system’s protective features working exactly as designed.

Verdict
The clearest difference is price: ThermoHammer at Free against APSI Bench's $0.99. ThermoHammer also leads on update cadence (every 3 days vs every 21 months) and iOS requirement (16.0 vs 18.0). APSI Bench's advantage is device support (4 vs 2). On ads and in-app purchases there is nothing between them.
