To add a little bit to this and why I am so principled against this. I will subscribe to a service, because a service means ongoing work. If you spent months or years building software, and have finished it, charge people what you believe is fair for the work you did up to now. Charge $50, charge $500, your call, sell to 1M people, your call. You have no running costs, you're just selling an app.

If you were running this on some cloud, maybe had some other extras built in that cost you time and money, then there could be a subscription.

If you want to keep your software updated, and are pushing updates daily, weekly, monthly, etc, I could squint at a subscription, but I would rather you just do critical fixes (bc if your product is broken you do owe paying customers a fix without a charge), and put new features in a new version that you will also sell.

People are selling git clients, calculators, db clients on subscription. it's crazy what the world has come to. We don't work to pay you guys rent.

The second I saw this app I was about to click buy (looking for a table plus alternative), went to pricing, saw subscription and immediately dropped it without even trying the free version.
