First guess is Idared, based on the pink overtones, but the sample is ripening a bit too early for this variety unless it is a stressed tree.
Other information that would help with identification is tasting. Idared would have soft flesh and taste somewhat like a Jonathan.
It could be a unique apple tree arising from a seed, and thus would have no name.
It has soft flesh, I can push my finger down with some slight pressure and put a dent in it.
This is consistent with Idared, but I won't be able to be more definite without tasting and handling a fruit.
