Eve changing cycle length

Will <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> automatically change my cycle length and period length? I changed birth control methods and I'm just wondering, if the days of my cycle change, will <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> automatically fix that or do I have to do it myself? (e.g., changing 28 days to 30 days or something like that)
