If you’re looking for one to display on your screen overlay in real time (ie. not just post-landing like Volanta or STKP), you can check this one out which allows you to customize various overlays onto your screen and displays live VS information (among other things) and will freeze/capture your landing rate as soon as you’re wheels down. It’s simple, but does the job if that’s what you’re looking for (and free, with no account required):
