One off premium upgrade for short durations

[Crusoe1999]

I live in the UK where we have adequate domestic weather forecasts for my needs. However, when travelling round Europe I find your app useful. It seems a waste subscribing to the premium service to cover just a month, maybe 6 weeks every couple of years. How about an auto expire premium option that a one-off payment for a month (or a number of months, or days or weeks for that matter) could be made?

@Crusoe1999 Hi, thank you for your words about our app. Unfortunately, there are plans to adjust Premium subscription periods, I am sorry about that.
