The app function based on the designer. I as a customer find it clunky and slow to react. Where I find it clunky is the activity zones. App ignores them. I've informed Arlo and I'll give them small credit as they have tried. It actually worked through one upgrade and then taken away by another and has yet to return to proper functionality. It's slow to react to alerts, what I mean. When you receive a notification and call on it. The app either crashes, locks up or loads very slow.
