Nice Barometer but does not track without app open – Barometer & Altimeter Pro Review

One of the best ways to use a barometer is to look at the trend of pressure change. This is tracked in this app but only when you open the app can you set a data point that is graphed. Ideally this app should create a data point periodically and consistently all the time. I suppose there is some kind of IOS limitation preventing this from happening. Not as useful without that but otherwise nice interface.
