UPDATE:

Locale 1.4 includes significant improvements to the location detection system, reducing time to detect location changes by 20% while also improving battery usage by up to 50%.

The original goal of this request—reducing the delay of detecting location changes—has been met as Locale 1.4 detects location changes within an average of 4 minutes. We are therefore marking this request as completed.

Although this request is being marked as completed, we have ongoing research and development to keep improving the speed and efficiency of the location detection system further :).

(Original response)

By design, Locale has no user-configurable options. The goal is that Locale should “just work” without requiring users to fiddle with various options that could negatively impact the operation of the app. For example, asking Locale to check location every minute could cause the battery to drain within 2 hours at which point you might miss the train stop anyway.

Although a user-configurable option won’t be implemented, I see the underlying goal as improving how quickly Locale detects that location has changed. For Locale 1.3 and earlier, it can take up to 10 minutes for location changes to be detected.

I’m therefore repurposing this request for implementing improvements to the speed of the location detection system. Once these improvements are completed, a user-configurable update frequency will no longer be necessary.
