Question: Can you suggest a face recognition API that works with both desktop and mobile apps?

If you need a general-purpose face recognition API that works on both desktop and mobile apps, Luxand is a good option. Its SDKs and APIs have powerful face detection and recognition abilities, and they work on Windows, Linux, macOS, iOS and Android.
