I have created a macOS (desktop) app that has been gaining some reasonable traction over the last year. My current (and the only) pricing strategy is a fixed $16 one-time fee for the full app (can be installed on 2 Macs) and a free-to-use tier for the limited app. No recurring payments, no subscriptions. People are using the app and buying the license - so that's good.

I know that for SaaS-type products, the most optimal pricing strategy is almost always subscriptions, but what about desktop apps? What are your experiences (as a creator and as a user of such apps)? Should I change it to something like: - free tier (limited app) - one-year license fee (lower than the current price) - lifetime license fee (as it is now)

Or should I keep it as it is and stop thinking about it for now?

Thanks for any suggestions.
