This feature would streamline the booking process and help users plan their trips more efficiently. ### 3/5 — Pre booking premium bus issue *2026-07-14* Premium busses booking always it shows the bus gonna starts from koyambedu if I am at velachery I could see bus coming near velachery may be it wil 2 bus stop before the velachery I can’t book that bus even I choosing that bus from live track it show book ticket for the bus while booking it shows the slots which starts from Cmbt only it will coming after another half and hour I understand it’s earcly booking but regular based on the time we need on time bus booking as well ### 5/5 — The best app for local transportation *2026-06-18* Makes travel across modalities seem less, informative , the interface is easy and navigation is seamless. All the best and continue the good work with regular updates and improvements ### 5/5 — Enhancement Request: Boarding Point ETA and Booking Availability *2026-06-09* The Chennai One app is extremely useful and has made commuting much more convenient. I appreciate the effort put into building and maintaining the platform. I would like to request a couple of enhancements that would further improve the user experience: 1. Display estimated arrival time at the selected boarding point I frequently book the P570S bus from Guindy to Velachery and vice versa. Currently, the app displays the departure time from the bus’s starting location, which is usually Koyambedu or Siruseri. Because of this, it is difficult to estimate when the bus will reach my actual boarding point (Guindy or Velachery). It would be very helpful if the app could display the approximate arrival time at the user’s selected boarding point. This would make journey planning much easier and more accurate. 2. Allow booking until the bus reaches the selected boarding point Recently, I have been unable to book tickets once the bus departs from its starting location. For example, if a bus leaves Koyambedu at 6:15 PM and reaches Guindy around 7:00 PM, I was previously able to book a ticket for boarding at Guindy until the bus actually reached Guindy. However, starting this week, booking appears to close as soon as the bus departs from its origin (6:15 PM), even though my boarding point is Guindy and the bus has not yet reached there. As a result, I am unable to book tickets after 6:15 PM for that service. It would be great if bookings could remain open until the bus reaches the selected boarding point, as was previously the case. ### 5/5 — Chennai’s all in one Transport App *2026-05-17* When you’re hustling through the city and you happen to use the Public transport, payments might be a problem; trying to find the right denomination of money is a huge task. This App solves it all, indeed a solution I was long waiting for. Payments feel seamless through the Bhim App and other Payment Gateways. Using Bhim you get 10% Cashback. ### 2/5 — App Force close (Black Screen) *2026-03-14* I updated to the latest version of the app, but it is not opening. When I try to open it, a blank screen appears and the app suddenly closes. Before updating to the latest version, the app was working fine. I also tried reinstalling it, but the issues still persists. Kindly fix this issue.. iPhone 7 iOS version 15.8.7 ### 1/5 — Prime bus booking *2026-03-13* Absolutely the worst experience with Prime Bus booking. I booked a bus from Siruseri and the ticket clearly showed the timing and confirmed schedule. But the bus never arrived. After waiting for a long time, I found out that the bus itself was not even available, yet the ticket was still showing as scheduled and active in the system. This is completely unacceptable and extremely unprofessional. On top of that, I lost my money. They even mention in their policy that even if the issue is on their side, they will not return the money. This makes it look like they are running the Prime Bus booking option just for money extortion rather than providing a real service. I also raised a concern with their support team, but there has been no reply from them at all. No response, no accountability, nothing. This is a terrible service and a complete waste of customers’ time and money. I strongly warn others not to trust this Prime Bus booking option. ### 3/5 — About the premium bus service *2026-03-13* I would like to bring to your notice an issue regarding the premium bus service operated by Metropolitan Transport Corporation (Chennai) from Thiruvanmiyur to Kalaignar Centenary Bus Terminus. Even after the bus departs from the origin point, the reservation slot for the bus continues to remain open for booking. This creates confusion for passengers and may lead to inconvenience. I kindly request the concerned authorities to look into this issue and ensure that the reservation slot closes once the bus departs, so that passengers are not misled. ### 5/5 — All in one *2026-03-04* I generally don’t write comments. But this application made me to … It is an all in one application its tracking system works seamlessly fine even though it is beta and it’s very easy for the passenger to book tickets under pressure…. This application is UX first application Like it priorities Users 💯🔥 ### 1/5 — Please Allow Email Login – Not Everyone Has an Indian Phone Number *2026-02-27* I recently tried using the Chennai One app and noticed that it mandates login using only an Indian phone number. This is quite inconvenient for foreigners and NRIs who may not have an active Indian mobile number. How are they supposed to access the services? In today’s time, with increasing privacy concerns and AI-based spam calls/messages, many users are not comfortable sharing their phone numbers unnecessarily. The app should definitely provide an option to sign up or log in using an email address instead of making phone number mandatory. Chennai One is meant to be a public-facing app, and it should be inclusive and accessible to everyone, including NRIs and international users. Request the developers to kindly consider adding email-based authentication for better flexibility and privacy. ## Frequently asked questions about Chennai One ### What public transport options does Chennai One cover?
