Halide is 2.99 a month, or 12.49 a year, and has been a subscription model since 2020. Sure, you have a one-time purchase option, but it is $70. I believe people who bought before the subscription got one year free, but things like widgets aren't supported. So unfortunately, that is likely the same fate for Kino.
