PRONTO makes buying fares for MTS and NCTD easier than ever. Add money to your PRONTO app, then scan your phone at the validator each trip you make. Our pay-as-you-go function means you always get the best fare! When using the app, hold your phone 5 to 6 inches below the validator to scan your barcode.

The PRONTO app can also help you plan trips, see real-time arrivals, get service statuses, save favorite stations, and find stops for San Diego County area transit so you can plan your trip around San Diego without any problems.

Always Get The Best Fare
With PRONTO, you can pay-as-you-go* by adding money to your PRONTO account with a credit or debit card. Every time you scan your app, the appropriate one-way fare is deducted from your balance. Look for validators at Trolley, SPRINTER and COASTER stations, and onboard buses.

You will never be charged more than a Day Pass ($6 Adult or $3 Reduced Fare) in a given calendar day, regardless of how many trips you make. Likewise, you will never be charged more than a Month Pass ($72 Adult or $23 Reduced Fare) regardless of the number of trips in a calendar month.

You can track your progress toward a Day or Month Pass in the PRONTO app.

*Pay-as-you go features not available for COASTER (must prepay for Day or Month Pass).

Poorly Programmed

This app feels like it was done as a high school project. The fields in the signup aren’t labeled correctly so they don’t trigger the iPhone’s autofill properly, including the password field doesn’t trigger the phone to suggest a password and save it, so I had to make up my own and then manually go to Settings>Passwords and save it there. This is all automatic in most apps.

Doesn’t support ApplePay so you have to fill in field after field to add your payment card.

What’s with all the security? This isn’t a banking app. If someone broke in, all they would get is a few free bus rides.

And to think this is what Bytemark (the app’s developer) does for a living!

Ultimate Failure

I just changed phone recently and tried to transfer my existing virtual card from my old phone to my new phone. When I clicked on ‘transfer existing card’ it prompted me that transfer failed and blocked my card so I couldn’t use it anymore. I called the Pronto help service, and they helped me went through the same failed transfer, blocked card, unblock card on their end, failed transfer again. It happened 7 times during my call to help service. In the end, I gave up. Now my card is blocked and I can’t unblock it from my end. No more purchases can be made.

Honestly, this app is such an amazing failure that it should be put into a textbook of most classical programming disasters. Have the programmers even looked at people’s complaints? Your app is supposed to be the backbone of public transport, not the one who denies it. I rarely write such a harsh comment, but this is just ridiculous because CompassCloud was so well developed compared to this one. You can do it, but you choose not to.

A help file would help

I think that I have my account on the app setup, the proof will be when I try it on a bus, thank God I also have physical Pronto card.

Now I had to bulldoze my way into setting it up because I couldn’t find any help or FAQ on the app, a link to the Pronto website is not the way to do it even if app help existed there.

For those of you having trouble I think that the best thing to do is set up your account using a web browser on a Mac or at least an iPad. Then you can log into the app with email and password, fire up the bulldozer and shove your way through the settingd get your virtual card set up.

I am disappointed in the programmers in that my profile is not complete on the app. A well designed system should bring over my address and phone number that is included on the website instead of just my name.

Of course this is version #1 and it should improve over time, but a professional designer would test the system by observing non tech people using it.
