It's easy for me, as I'm an Egyptian living outside of Cairo (and therefore not able to use buses), to schedule my trips by myself using this app! The service itself isn't great though, sometimes it doesn’t work at all or shows incorrect prices when you try booking more than one trip per day/week etc..
Also they don't have some services that are available through other apps like Uber but they do offer bus passes too which makes up for it somewhat. Try out their discounts if there are any - its cheaper than normal busses otherwise :) Great option for those who live far from cities and want something cheap & convenient instead of taking taxis every time they need transport around town.
