Shift Calendar & Work Schedule

I like the app, however I see some things that just aren’t right.. for example to select 3 days at once you have to pay 4.99 a month.. why not let people have the option to select 3 days at once and have other things like adding notes to certain days or more colour options as the option for monthly payment.. in all honesty it’s like robbery if I honest, especially when there is other apps that let you do this for free.
