> The features you unlock are permanently available and any other pro features added the next 12 months after purchase are also permanently available. After one year new pro features introduced will be locked until you purchase a upgrade. Even if you do not purchase a new unlock after 12 months, the app will still be updated with improvements and bug-fixes.
Yes! I was going to comment the same, it's a very reasonable model from a developer who makes great software. I recently within the last year switched from the Blink shell to his app "Shellfish" as it's become a daily part of my workflow when using my iOS devices. I highly recommend it if you like workingcopy.
there's a difference between temporary feature flags which eventually go away and permanent ones. say you build a new feature that has some overlap with an existing feature flagged one, and you unify some of the UI for it. now you have to always check what the UI looks like with one feature flag, with both, with none. as time goes on this gets worse, and maybe 3 or more features start overlapping in some way. If you're just using feature flags for A/B tests, this is manageable, but over time it can get really messy.
