I have been using Youlars app as a parent and Edulars as a teacher. Youlars provides transparency in communication, ease of use, and loads of exciting features which keep me engaged as a parent and my children love it for day-to-day activities. Features like Hall of Fame, Youlars Shield, and quiz make it unique and engaging.
Edulars on the other hand is the first app designed for us as teachers and school administration, that I know of. Edulars allows us to track day-to-day activities, manage work staff load and also manage day-to-day operations like student communication, attendance, and leave management. Overall extremely satisfied with these 2 most used apps on my phone.
