AQtime review
A Windows desktop profiler for performance, memory, coverage, and code analysis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AQtime is SmartBear’s Windows desktop profiler for developers investigating performance bottlenecks, memory use, resource leaks, and code coverage in desktop or service applications. Its documented profiling support includes native and .NET code; selected profilers also support Java, VBScript, and JScript. The product is aimed at teams that need to analyze application behavior across those environments rather than a cross-platform profiling workflow.
Its main strength is the breadth of its profiling modes. Sampling estimates time spent in routines by polling running applications, while performance profiling measures execution time, call counts, call hierarchy, and performance counters. The allocation profiler tracks allocations, deallocations, memory use, and potential leaks. Results can be organized by operating-system or .NET runtime threads, and coverage profilers report whether routines or lines ran. Static analysis also reports method dependencies using application debug information. This makes AQtime relevant when a team needs several kinds of diagnostic evidence in one profiling product.
AQtime is a paid product with fixed-license and floating-license plans. That choice suits teams deciding whether a license should be fixed or floating, while teams seeking a free plan or a profiler for another operating system should look elsewhere. The listed deployment model is desktop, and the documentation describes 32-bit and 64-bit application profiling. SmartBear’s documentation consulted applies to AQtime 8.81 and was last modified in 2022, so buyers should weigh that documentation context when assessing fit. AQtime is most suitable for Windows teams working with native or .NET applications that value performance, allocation, thread, and coverage analysis; it is less suitable for teams requiring a cross-platform or free option.
AQtime pros and cons
- Where it wins

- Includes coverage profiling and static method-dependency analysis.
- Where it doesn't
- Windows-only desktop deployment limits platform options.
- Paid product with fixed and floating license plans.
- Documentation applies to AQtime 8.81 and was last modified in 2022.
