That doesn't answer the question that was asked. The person above didn't ask about the workflow of negotiating recurring vs. singular payments with financial services. Some other 'mysterious' factor pushed this business to monetize their non-recurring service with a recurring payment. The question is if there is even a semblance of reasoning to make this a subscription (especially one with this kind of a pricetag), or if they made a purely local app once and just wanted to rent it out for more money.

I was implying it. Because recurring payments are such low friction today, there is very little to no incentive for creators to offer one-off options. For every 12 potential buyers who would scoff at the recurring payments, there is one who can cover 12 months worth of revenue.
