common app v school app

ive seen some ppl on these forums say that some schools prefer the school app to the common app. does anyone know if using the common app puts you at a disadvantage? should i do all my schools on their own apps? thank you

<p>Schools are required by law to treat the common app exactly the same as their own. There is no difference or preference.</p>

<p>i was accepted to my 1st choice school, using the common app. i really think that the "which app?" issue is a non-issue... it really does not matter.</p>
