Wrong. I would definitely pay for this and was interested in it precisely because I just bought n iPhone. I spend $500-1000/year on software.

But if there's a free tier I want to try out normal use patterns over the course of a week or a month, and I prefer one-time payments or token purchases to subscriptions. I do the latter only for my IDEs, and still don't like it that much.

My objection was to the free tier only allowing one to export 3 images a month. That seems bizarre to me, since in course of trying something for the first time you might make 5, 10, or 20 images in an hour. If I'm running into a monthly limit in the first few minutes of using a tool, my immediate reaction is that it's something I can live without.
