Deputy vs Sling: Which is best for you?

I've used Deputy in multiple organisations in restaurants, events and education settings over many years and it has always been pretty reliable, though I don't think it developed as quickly as other similar software packages and started to lag behind a bit.

When employee enters a punch that overlaps with a time off request, the kiosk doesn't log the punch or notify the employee that there is an issue.

I'm using the trial of the business premium & love the geofencing/clock-in feature, however, I found that if you accidently clock out, you cannot edit the clock out or clock back in until your next shift.

Some automation features are lacking in the free version, and I sometimes have to spend additional time manually adjusting schedules for last-minute changes.
