Just okay. Too slow for iPhone

Ive had this app now for a most two years. After each app upgrade, the app seems to work slower and slower. Sometimes it takes so long to retrieve data, that Ive given up all together and just called the local ASOS number. I have the latest iPhone and it continues to be a slow app. Ive switched to another aviation weather app that is lightening fast, with no b.s. This on has the potential to be great with its easy features, but it just drags. This is unacceptable when in the flight line to get a last minute and up to speed wx check.
