Won't work without granting "always" location access – Sunrise Sunset Lite Review

Currently, you have to allow this app to ALWAYS access your location, even when you're not using the app, for it to work. Seems sketchy for an app that I'll only look at every couple months. Why not implement a zip code option? Or, if you MUST use GPS, why not implement a location 'only while using the app' option?
