Unreliable updates

Will sometimes be 2 days out of date, has to be force quit and restarted to update.

Used to work

This app worked fine when I first bought it a year ago, but now forecasts often fail to update, and if they do eventually download the individual pollen listings are hard to read because of many duplicates. It is now much faster and easier to get the free pollen report from the Weather Network or other similar apps. I have cancelled my subscription, which makes me sad because I like to support small developers who make useful dedicated apps without ads.

Doesn’t work

App doesn’t work anymore. Even when it did it was very slow. Useful when it worked but it seems support for this app has ceased.
