RCM/ABRSM Lv1-4 relevant apps/software?

[happypennygames]

Are the many piano learning apps practically beneficial for seriously advancing through a formal conservatory program?

Any music educators/players/ self-taught folks recommend particular ones?

a) Programs for musicianship: ear training, sight reading?

b) Programs for repertoire development?

I am both a beginning adult piano learner and also an app developer myself, but very "structured curriculum focused" hence my interest in the rcm/abrsm programs.
