I’m a weekender - building a desktop app (OS X & Win) for individuals and small businesses. I hope it turns into a real business some day, but as experience would show, it probably won’t.
On the low end, $24/month is way too much for me. I would find it offensive to pay $24/month for a licensing solution, when I pay $0 for python, flask, electron, NPM, Vue, and the myriad other technologies I rely on heavily. (Note, I don’t think it is offensive - but I feel it.)
My gut feel on pricing - don’t try to squeeze money from a stone. Give away the low end. You won’t make much money there anyway and you will almost certainly turn off many potential users and proponents. Get them hooked. Let them promote for you. Don’t let them find an alternative. Then, when they start making money, you start making money.
If I have a viable business going I will have a totally different feel on how I would see this expenditure.
2 cents for you.
