Note that all PowerApps that you buy are usually coming with 1 year of updates. So, buying individually works well if you only need a few of apps. Otherwise Pro plan is more cost effective, plus you get direct support via email.
I am sort of confused too because the power apps usually are listed as subscription, not one time buying. I see them listed anywhere from $50-100 per year not as a one time buying option. Does the option to buy one time instead of subscription appear in a link somewhere?
If there is no one-time purchases, I will gladly be going back to Dolphin... UNA is far too costly to get the same features that Dolphin had for FREE.
Such as banner ads, user classifieds, maps, etc.
I wanted to use UNA and I wanted to love it but its still too new I guess, for that matter. I don't have $50 a month and I certainly dont have hundreds for yearly subscriptions for a website that may or may not even have an active userbase.
Brianna Coyle , note that the subscription is not compulsory — it is only for getting updates and support. If you buy once and decide to never pay again all the apps would still work and you’re not expected to pay. Paying will allow you to access automatic updates and request direct support via email.
