Air call has been great. So far we have experienced a few shutdowns of the app over the past 2 months. But they were taken care as our manager coordinated the fixes with an aircall rep. So that was good, but i think it's better that it doesn't crash in the future. The notes section is amazing on aircall so far. What I would love to have is a dark theme for Aircall. Dark screen is something that always makes things look great.
