When people ask "What is the most used betting app?" the answer depends on what they mean by "most used." This short guide clarifies the common metrics-revenue share, downloads, and monthly active users-and offers a simple framework to judge which app matters for different goals. The article focuses on how to interpret public evidence, why state-level reports matter for U.S. comparisons, and how seasonality and promotions can create temporary shifts in install rankings. It presents practical checklists and examples so you can pull credible conclusions from the right data.

"Most used" depends on the metric: revenue, downloads, or monthly active users, and each tells a different story.

State regulator revenue tables are a practical way to verify which apps lead in your local market.

Downloads spike around major sports seasons, but revenue share tends to be more stable.

What "most used" means for top betting apps

When readers ask about the "most used" top betting apps, they usually mean one of three things: where most money is placed, which apps install most often, or which apps have the largest active user base. Start by defining those metrics so you can judge claims against the right question.

Revenue share measures where customers put real money and is often the best measure of industry power because it reflects product depth and liquidity. Industry trackers and operator disclosures indicate that one company led U.S. online sportsbook revenue through 2024 and into 2025, which frames revenue-based answers; see the Legal Sports Report market tracker for that pattern Legal Sports Report tracker. Other market summaries are available from independent trackers US Sportsbook Market Share.

Downloads count installs over a period and show short-term popularity, for example around a major season or promotion. Monthly active users, or MAU, track returning engagement and are the closest available proxy for regular use but are often proprietary and not disclosed publicly.

Using the words precisely matters: when someone asks "what is the most used betting app," ask whether they mean revenue, downloads, or MAU before drawing conclusions.

A snapshot of U.S. leaders: revenue, downloads and active users

Industry trackers and operator filings consistently placed one operator ahead of competitors in national online sportsbook revenue into 2025, with another major operator typically in second place; those market-tracker findings summarize operator disclosures and aggregate state data Legal Sports Report tracker.

The American Gaming Association places the broader commercial gaming industry in a growth context, noting that U.S. commercial gaming revenue remained substantial in 2024, which frames continued demand for sportsbook services AGA State of the States report.

Downloads and installs often spike around the NFL season and other major sports windows, so short-term leaderboards based on downloads can show a different set of top apps than annual revenue rankings. Promotional intensity, bonus offers, and seasonal demand explain much of the install volatility.

What state regulator reports reveal about local leaders

Several state regulator tables list operator mobile sportsbook revenue by month, and those reports frequently show the same operators leading in key months, which strengthens the national picture when both sources align. For recent state-level operator revenue tables, see the New York State Gaming Commission data New York State Gaming Commission reports.

New Jersey regulator tables perform a similar function for that market, showing operator revenue by month and helping explain why market shares can differ from state to state New Jersey Division of Gaming Enforcement reports.

Reading monthly operator revenue tables lets you confirm whether a national tracker’s leader is also the leader in a local market or whether state-level factors create a different ranking. Find monthly summaries on the Funded Plays blog Funded Plays blog.

Revenue share is a stable indicator of where money flows, but it can be influenced by tax rates, fee structures and product mix; industry trackers aggregate this view across states to create a national snapshot Legal Sports Report tracker.

Downloads capture short-term attention and marketing success. They are easy to measure via app-store data but include one-time installs, re-installs and churn, so they can overstate sustained use.

Monthly active users are the most direct measure of regular engagement but are often private to operators. When available, MAU helps answer whether an app is truly used week after week instead of briefly during a promotion.

How regional and market conditions change which app is 'most used'

State-level tax regimes, promotional rules and differences in product mix (for example, parlay options, live-betting features or odds displays) cause material state-by-state share changes. Those local differences explain why a national leader may not be the leader everywhere.

Mature international markets, such as the UK, have different dominant apps and a larger share of activity conducted online, so U.S. rankings do not translate directly to those markets; the UK Gambling Commission’s statistics illustrate market structure differences abroad UK Gambling Commission industry statistics.

How should I interpret claims that an app is the "most used" among top betting apps?

Ask which metric is meant-revenue, downloads, or monthly active users-then verify with a national tracker and local regulator reports for the relevant date range and jurisdiction.

If you care about the most used app where you live, start by checking the regulator reports or local industry trackers before relying on national headlines.

Typical mistakes when people ask 'what is the most used betting app?'

Mixing metrics: treating downloads as synonymous with active use. A high install count does not guarantee sustained engagement, so confirm whether counts are installs or active users.

Assuming national rankings apply uniformly across all states. State taxes, market entry timing and promotional strategies often change local standings, so a national leader may not dominate in every state.

Overlooking dates: installs and revenue can swing around major seasons, so check the reporting period and whether a ranking reflects a single month or a full year.

Practical examples: which top betting apps are most used for different user needs

For a bettor who prioritizes liquidity and deep markets, revenue leadership matters because it usually indicates larger pools and tighter markets; industry trackers that compile national revenue data can help identify those operators Legal Sports Report tracker. Additional operator statistics are compiled by Business of Apps DraftKings statistics.

Casual or seasonal users may care most about promotions and install offers timed to major events, so download spikes during the NFL season can make a different set of apps feel most used for short periods.

International users should consult local regulators or market reports because dominant apps in the UK and Europe differ from the U.S. leaders, and the UK’s official statistics provide a clear view of local market structure UK Gambling Commission industry statistics.

Seasonality, promotions and short-term shifts in the top betting apps

Major sports seasons, most notably the NFL, create predictable spikes in downloads and short-term installs because fans re-engage or new users try apps for a specific season. Trackers that publish monthly install rankings often show those spikes around season openers and playoff windows.

Revenue share tends to be more stable across the year but is still affected by major promotions, market expansion and structural changes in taxation or market rules. The AGA’s overview of commercial gaming revenue provides context for overall growth that supports sustained sportsbook activity AGA State of the States report.

When a major promotion or aggressive welcome offer appears, installs can surge and temporarily change the download-based leaderboard. These shifts often reverse once the promotion ends, so short-term install leadership is not the same as sustained market leadership.

Practical month-to-month checklist when you watch leaderboards during a season:

Confirm the metric: is the list ranked by installs, active users, or revenue?
Check the date range: single month, rolling 30 days, or year-to-date?
Note concurrent promotions or product launches that could cause temporary spikes.
Cross-check with state regulator revenue tables if the question concerns local market leadership.

Using this checklist helps you avoid misreading a promotion-driven install surge as a permanent shift in usage patterns, and it makes monthly comparisons consistent.

Bottom line: deciding which of the top betting apps matters for you

Pick the metric that matches your goal: choose revenue share to identify market-leading liquidity and product depth, downloads to find where short-term popularity is highest, or monthly active users to see where regular use is strongest. Industry trackers and state regulator tables are the most reliable public sources to verify those metrics Legal Sports Report tracker.

For U.S.-focused questions, start with national trackers and then confirm with state regulator reports to account for local tax or promotional differences; state tables help you see whether a national leader also leads in your state New York State Gaming Commission reports.

Remember, one operator led U.S. online sportsbook revenue through 2024 and continued as the largest brand into 2025 according to industry tracking and operator disclosures, but "most used" depends on metric and region Flutter Entertainment annual report. See reporting at CBS Sports FanDuel vs. DraftKings.

Next steps: decide which metric matters, pick two credible sources (an industry tracker and a state regulator table), and rerun the simple checklist you used earlier when new monthly data or seasonal promotions appear. For a quick site overview, visit the Funded Plays homepage Funded Plays.

How do downloads differ from active users?

Downloads count installs over a period and include one-time installs and re-installs, while active users measure returning engagement and better reflect regular use.

Which public sources show app revenue in the U.S.?

National industry trackers and state regulator monthly operator revenue tables are the main public sources for operator revenue comparisons.

Does the most used app in the U.S. match the leader in the UK?

No. Mature markets like the UK have different dominant operators and a larger share of online activity, so leaders differ by region.

Deciding which app is most used starts with a clear question and a consistent metric. Use industry trackers and state regulator tables to verify claims, and recheck during major seasons to avoid mistaking short-term spikes for durable leadership. If you want to apply this approach, pick your metric, gather the two data sources suggested in the article, and run the short checklist each month or after major promotions to keep your comparison accurate.
