What is the difference between 2 Photoshop subscriptions?

Question

Adobe Photoshop

I want to buy a subscription to Photoshop, but I don’t know which one to choose.
There is a plan "Working with photos" for 644 rubles / month. and "One application" for 1288 rubles / month.
If you think logically, then it is more profitable to purchase a subscription for 644 rubles, because there is a Photoshop there and there, but the price difference is confusing. Maybe there are some pitfalls? What subscription are you using?
ps Photoshop is needed for web design.

Answer 1

Maybe there are some pitfalls?

No, I've been using it for three years already - no pitfalls. This is just a promotional offer, theoretically, it could end at any time.
