One app · One wallet · Every road

The toll tag is already in their pocket.

It's a mobility wallet too, qualifying drivers for incentives and paying for transportation services.

Every program an agency runs. One phone. One wallet.

02Then it does what a tag can't
01

Tolls.

99.97% accuracy on SR 520. When the camera misses, the phone still creates the toll.

02

HOV.

110,000+ DFW drivers verified. Violations cut from 30% to under 2%.

03

Mode.

Drive-alone, carpool, walk, bike, transit, telework commutes — classified automatically.

04

Mileage.

2,000 vehicles verified weekly by odometer photo or telematics integration, with fraud detection built in. The engine behind LA Metro's One Car Challenge.

05

Support.

AI resolved 90% of Seattle driver issues with no staff time. Hey Tolly brings the same support to every toll in America.

06

Wallet.

Verified incentives, spent tap-to-pay. Restricted to transportation when the program says so.

03Proven at 99.97%

05One wallet

One wallet in. One wallet out.

Fare and toll platforms move money. None of them prove a carpool happened or a mile was driven. GoCarma does both — credits from any program land in one wallet, spent through Apple Wallet and Google Wallet.
