High Roller Technologies has launched an iPhone app for its ROLR prediction market platform, expanding mobile access to the service less than three weeks after its commercial web debut on Oct. 21.
The iOS launch follows ROLR’s initial rollout to eligible US customers, bringing sports, politics, entertainment, crypto, economics and climate event contracts to a dedicated mobile app. Users can browse markets, trade contracts, track positions and manage their accounts.
“Launching the ROLR mobile app puts our platform directly in customers’ hands, making it easier to discover markets, act on their views and manage their positions wherever they are eligible to trade,” CEO Seth Young said in Monday’s announcement. “We believe a convenient, intuitive mobile experience is an important part of attracting new customers and keeping them engaged.”
The launch marks another step in High Roller’s effort to build a prediction market business alongside its existing online casino operations. Young said the mobile app gives the company’s marketing and distribution partners another way to reach potential customers. High Roller has also previously outlined plans for an Android app, although it has not announced a release date.
Inside the ROLR app
In a hands-on look at the new app, NEXTPredict.io found a clean, intuitive interface that will feel familiar to users of established prediction market platforms such as Kalshi and Polymarket.
Sports dominates the available selection, with the app displaying 1,349 game markets and 183 futures markets during NEXTPredict’s review. A manual count also found more than 150 political markets, approximately 120 culture markets, 32 crypto markets, 18 economics markets and six climate markets.
ROLR markets are organized into categories covering sports, politics, culture, crypto, economics and climate, with a scrolling ticker displaying recent trades across the top of the screen. The homepage also highlights upcoming events, including Monday night’s Buffalo Bills-Minnesota Vikings NFL game and tennis matches scheduled for later in the day.
Individual market pages feature interactive price charts with adjustable time ranges, alongside contract prices and Yes/No trading options. The search function is responsive and makes finding specific markets straightforward, while the app offers both light and dark display modes.
Account management is similarly accessible, with a slide-out menu providing access to portfolio balances, trading activity, funding options, account settings and customer support. Users must complete identity verification before funding their accounts and trading.
Crypto.com partnership powers ROLR trading
ROLR does not operate its own exchange, instead offering event contracts listed on Crypto.com Derivatives North America (CDNA), a Commodity Futures Trading Commission (CFTC)-regulated exchange and clearinghouse.
High Roller’s subsidiary ROLR US LLC operates as a registered introducing broker, connecting customers to Foris DAX FCM LLC, the Crypto.com affiliate responsible for carrying customer accounts. The app uses technology licensed from mrkts.com.
Trading is restricted to eligible US customers, with ROLR’s terms of service identifying eight states where the platform is unavailable: Arizona, Illinois, Maryland, Massachusetts, Michigan, Nevada, New Jersey and Ohio.
Those are the same eight states where Crypto.com has stopped offering sports event contracts. ROLR’s restrictions are broader, however, applying to the entire platform rather than sports markets alone.
The app also features a ROLR Points rewards program offering 500 points for account verification and another 500 for completing $5 in qualifying trades. The 1,000 points can be redeemed for $10 cash, subject to program terms, while a referral rewards program is listed as coming soon.
