AIDA64 is described as 'System information and diagnostics utility, 64-bit CPU and memory benchmarking, real-time hardware monitoring, advanced system stability testing, and export options in multiple formats' and is a very popular Benchmark tool in the os & utilities category. There are more than 50 alternatives to AIDA64 for a variety of platforms, including Windows, Linux, Android, Mac and Android Tablet apps. The best AIDA64 alternative is HWiNFO (32/64). It's not free, so if you're looking for a free alternative, you could try HWiNFO (32/64) or CPU-Z. Other great apps like AIDA64 are Open Hardware Monitor, GPU-Z, Mission Center and HWMonitor.
For viewing data realtime while testing hardware it is great. The graphs a good as well. But this tool does not provide a customizable sensor screen view like AIDA64.
