It’s worth it

Some guy gave it 2 stars because there is no manual…. You should at least know what the knock out strategy is before getting this app. I think it’s well done. You can adjust card speeds and it really forces you to practice basic strategy and keep the count. It’s well worth the price if you want to because an AP I think it’s a great tool.
