Malus domestica 'Triumph'
Triumph is a new cold-hardy disease-resistant apple, released in 2021 by the University of Minnesota.
The apples ripen towards the end of September, and have a tart flavor. They can be stored in a fridge for 3 months or more.
Triumph is a cross between Honeycrisp and Liberty, and can perhaps be regarded as an improved Honeycrisp.

Triumph appears to have resistance to fire blight and scab, but some susceptibility to cedar apple rust. It is a good choice for organic growers.
As you would expect from a variety from Minnesota, it is reliably cold-hardy to zone 4.
