I’d prefer to just pay whatever price that’s asked if I see value in the app. So if you normally charge 6.99/mo just charge me a year’s worth and if you want more money from me, release a paid update that’s worth paying for.

I know this probably is less profitable for devs since most people are cheap but that’s how I’d like to use things.

If the app requires continued maintainence (databases or heavy backend operations) it's going to be a continuing cost. I'm not sure if a one time payment can sustain it, but Im hopeful about a microtransactions model. Which is what I'm thinking about for formstr.
