Uber Taxi VS grabTaxi on available taxi around

Depending how you look at this

This is from customer passenger prospective

1. uber

  

to be fair ten minutes there are four taxi

while taking to you

2. grabtaxi

btw there is promotion for grabcar

3. ComfortDelgro citycab

ps can not compare comfort as it app dun

have taxi that moving around real time map

but i am sure there are equal amount of comfort/citycab taxi

in my area at this moment

also once you book comfort taxi

pax told me she can see my taxi coming to her

so Apple can not compare to Orange !

PS: I dun see Uber real time maps

on passenger ask for taxi

unless I have to get the ubertaxi app

4. LTA taxi taxi@SG app

Conclusion, none of the above passenger app

is useful FOR drivers to find passengers
