Has change my life and for real; it's "awesome note" even though the inbuilt calendar has appointment settings and even though there a lot of apps out there which make todo, awesome note is the one i use to do every personal things, when i say every personal thing i mean everything. Appointments, todo, notes, dairy, quick notes, time tables, grosseries, wallet, safe box for passwords, that app manage all my personal stuff by making it follow a diet, a schedule and a lot of things, so that's what i can say has change my life.
