should i update my unity to get the latest update for stormcore app?

Like my title states, i am very new to all of this. I have the stormcore beta on my phone, and i would love to use it but my unity esc is too out of date. I need to perform a software update but i am unsure on how to do this. Any warnings/imsight would be amazing because my prior nowlage is essentially 0 on this subject. Thank you all.
