Programmer Luigi F. Cruz has recently released a new SDR app called "CyberRadio". CyberRadio is a minimal SDR app, which allows you to listen to FM and AM radio. It does not have any spectrum analyzer or waterfall display. As it is based on SoapySDR, it supports almost every SDR including the RTL-SDR, and runs on Linux, maxOS Sierra, Windows 10 and ARM SoCs.
Luigi also notes that he has made use of cuSignal and Numba functions which enable GPU acceleration on CUDA compatible graphics cards.
The app is still in pre-release status, so no binaries are available. However, Luigi has provided installation instructions for Linux on the GitHub.
