I like that it helps me keep track of my schedule, makes sure everything goes smoothly for meetings or events while also keeping in touch via email if there are any issues arising from being out late at night (which happens quite often).
It's easy enough anyone can use without having too much experience but you do need some basic knowledge about how scheduling works before using this service as well! If your looking into an app where all aspects will be taken care off by someone else then maybe look elsewhere? This isn't really meant just purely used when traveling alone though so not everyone has access/needs something such as these services which help organize things better than paper planners ever could have done otherwise. Being able utilize online resources instead allows more people who would rather plan their own schedules easier because they don’t necessarily know what kind tools exist yet since most apps still require users needing assistance.
