- Hello, rider
Your commute, but rewarding.
RailRobin rides the metro with you. A live next-station board, Robin the AI that answers with official sources, and quick games that turn your ride into coins for real rewards.
Coming soon to Google Play. Android first, iPhone next.
How it works
Three stops to a better commute
No new card, no new ticket. Ride the way you already do, and let RailRobin make the minutes count.
Check in at the station
Start Metro Mode and pick your stop. We check your location once, at the station, then switch it off.
Ride and play
The next-station board keeps you on track. Quick games pay coins during your ride's 90-minute window.
Spend at partners
Swap coins for rewards from cafés and shops at or near stations. Show the voucher at the counter.
Metro Mode
Never miss your stop again.
A next-station board in your pocket that works even in tunnels, because it runs on the timetable and the clock, not on GPS.
- Live next-station boardYour line, your direction, the next stop and minutes to go. Tap “I'm at” to correct it any time.
- “Your stop is next” alertsA buzz one stop before your destination, even mid-game.
- Saved stations and interchangesHome, office, the usual. Plus a heads-up where you change lines.
- Crowd reportsQuiet, moderate, busy or packed: riders tell riders, and reports vanish after a day.
- Share my tripSend family a live link with your stations and arrival time. Never your location.

Location is checked once when you start Metro Mode, then switched off. During the ride, location is used only if you turn it on, and it never leaves your phone.
Robin AI
Ask anything about your metro. In your language.
Robin answers questions about fares, exits, rules, parking and lost property, and shows the official source under every answer.
- Cited, not guessedAnswers come from reviewed operator pages and RailRobin's own map, with the date each was last checked.
- English, ಕನ್ನಡ, தமிழ், हिन्दीAsk the way you speak. Robin replies in the same language.
- Private by defaultPhone numbers and emails are removed before a question reaches the AI model. Your name and number are never sent.
- Underground? The guide still worksRobin needs signal. The Metro guide is on your phone and works offline.

Data in India where we can
Our servers and database run in Bengaluru. Bug reports and error logs stay in Central India.
No selling, no profiling
We don't sell personal data. Sponsored items are chosen by city and date, and always labelled.
Fair rewards
One account per phone, verified check-ins and daily caps keep coins honest for everyone.
Two-person review
Every story, fact, theme and sponsored item is approved by two people before riders see it.
