Hope you enjoy Kino! To clear up a few things about Halide…
The only time Halide communicates with a server is when we do a controlled rollout of a feature, and anonymized reporting when a capture fails. I’d prefer we didn’t need either but 1) the App Store model doesn’t accommodate safe rollouts and 2) iPhone capture and photo library frameworks regularly break, and sometimes the only way to get a fix escalated is to have numbers in hand.
If you don’t want to subscribe to Halide, though, there is a one time purchase option in app.
