thanks for clarifying, Sam. I also don’t sell apps on any web site (for now). I know I will use AppWrapper if I begin to sell on the web.

Even non-sold apps can benefit of AppWrapper. Just giving your app, even freely, to others (by downloads) requires one of those:
• have the app signed¬arized
• if not, the user must manually force the OS to open the app, using hidden options (either a button in “System Preferences”→“Security&Privacy”→“Open (app anyway)” or holding the option key while choosing open in the contextual menu in the Finder (which often leads to closing the window, as it’s the same shortcut)).
You can see by the number of words that option 1 is the simplest
Of course, if you don’t give your apps to anyone at all, why doing all that and spending money for a developer account?
actually I sell apps to a very limited number of customers.
it’s not the appwrapper price that restrains me, it’s that I don’t want to pay apple $100 a year only for delivering apps to this small amount of customers …
IMO - it saves way more than $100 a year just in time savings. Even if it’s just for occasional app building.

Well, even if you don’t renew your Apple account, your certificates should still be good for several years.
The certificates are, but as far as I know, you can only Notarize apps if you have a valid and active developer license, i.e. you’ve paid your $100 a year. So for distributing outside of your team, you still need to pay it.
Apple’s CEO desperately needs that money, he took a 40% pay cut recently because things are getting tough.
