I tried both and would recommend this one (thanks Pete W), it worked first try. Just like @Mael said, bring it up during the lights or during previous session (I tested at race lights only), set up your options and later on just drive into the pits where the fuelling and tyre change etc will commence automatically.
Aside from working on all resolutions, this one also seems to correctly reflect the vehicle tyre selection, where the other one doesn't.
I couldn't get the other one to work at all. I set it up at the lights, drove into pits, and was just confronted with the regular pit menu with no pit activity initiated automatically. The potential pro for this one is the hotkey to bring the menu up mid-race for last minute set up or changes. However this didn't work for me either, so would have to bring up from the in car apps menu RHS of UI with the mouse as for the other app.
