It's easy to use from the admin side as well it has very good support team who are always available if needed at any point of time.
I would say that there maybe minor lags with some older devices but other then this everything works fine! Nothing much dislike about sign flow so far just wish more companies could implement them into their organization. Its really helpful when you want to manage your schedule easily without worrying too much about getting stuck up or forgetting things. Also its helps me keep track of my leave balance and also help control how many times i can go out per day etc.
