Mk Fuel to aplikacja do współpracy ze sterownikiem Mk Fuel montowanym w motocyklu. Po połączeniu z modułem BLE aplikacja pokazuje chwilowe spalanie, średnie spalanie, dystans tras A/B, spalone paliwo oraz szacowany zasięg na baku. Sterownik odczytuje impulsy wtryskiwacza, dzięki czemu może działać także w motocyklach, które fabrycznie nie pokazują chwilowego spalania ani zasięgu. W aplikacji można ustawić pojemność silnika, liczbę cylindrów, liczbę wtryskiwaczy, przepływ wtrysku oraz pojemność baku. Dostępna jest też kalibracja po tankowaniu, która pozwala dopasować wskazania do realnego zużycia paliwa z dystrybutora. Aplikacja korzysta z Bluetooth do komunikacji ze sterownikiem oraz z lokalizacji GPS do obliczania prędkości i dystansu trasy. Do działania aplikacji wymagany jest sterownik Mk Fuel.
