I use Real Dash with an IPad mini and it even picks up what gear I am in with my TKO and LS3. I don't know how it does it but it does. Plenty of skins to pick from and it will even display what music you are playing. Price is right too.

You can also use Dash Command. It looks almost identical to Autometer's app.
