This app is very useful may Allah make it heavy on your mizaan and a means for you to enter janna allahumma Ameen.
My suggestion to improve the app would be to allow a section that lets you link the stay before and the ayah after if that makes sense.
Eg if a person is memorising Surah Nas and he has memorised the first ayah and he has moved onto ayah 2, before moving onto the third, he must link ayah 1 and 2.
By linking the ayahs the persons hifdh is much stronger. بارك الله فيكم
