Second Screen Sports Apps: What to Use While Watching Live Sport
If you've watched a Premier League match, an NBA playoff game, or a cricket test recently, your phone was probably in your hand for most of it. You're not alone. The second screen isn't a trend anymore — it's the default behaviour for modern sports fans.
But here's the question nobody seems to be asking: what should you actually be doing on that second screen?
Most fans end up cycling between Twitter/X, their group chat, a stats app, and occasionally a betting app. None of these are purpose-built for the experience of watching live sport. They're general tools being bent to a specific use case. The result is an experience that feels fragmented — you're constantly switching apps, losing context, and missing moments on the main screen.
What Fans Actually Do on Their Phones During Games
Before looking at specific apps, it's worth mapping the actual behaviours. During a typical live match, fans are doing some combination of:
- Reacting — tweeting, posting, texting the group chat after big moments
- Checking — live stats, other scores, fantasy point updates
- Predicting — making mental calls about what happens next ("they're going to concede before halftime")
- Competing — wanting to prove they know more than their mates
- Wagering — in-play betting on live markets
- Researching — looking up player histories, head-to-head records, rule clarifications
The interesting thing is that predicting and competing — the most emotionally engaging behaviours — have the fewest dedicated tools. Social media handles reacting. Stats apps handle checking. Betting apps handle wagering. But "I think I know what's going to happen next and I want to prove it" has been largely unserved.
The Current Second Screen Options
Twitter/X
Still the dominant second screen for sports. The real-time feed during a big match is electric. But the experience is chaotic — spoilers, toxic hot takes, algorithmic noise, and no structure. You're not really doing anything; you're consuming other people's reactions.
Best for: Real-time reaction, breaking news, feeling the collective pulse.
Worst for: Any kind of structured engagement or competition.
Good for reaction, poor for engagementBetting Apps (Bet365, Sportsbet, DraftKings Sportsbook)
In-play betting markets move fast and there's genuine engagement in live wagering. But the experience is transactional — it's about money, not sport. The anxiety of real-money stakes can actually diminish the enjoyment of watching the game. And for many fans, betting just isn't something they want to do.
Best for: Fans who want financial stakes on outcomes.
Worst for: Anyone who wants engagement without financial risk.
Engaging but comes with real financial riskFantasy Sports Apps (FPL, SuperCoach, FanDuel)
Fantasy apps are enormously popular, but they're not really second-screen tools. The core activity — selecting teams, making transfers, analysing matchups — happens before the game. During the live match, you're just checking how your players are performing. There's nothing to do.
Best for: Season-long strategic competition.
Worst for: In-game engagement. The match itself is passive.
Great product, wrong time windowOfficial League and Stats Apps (ESPN, Cricbuzz, AFL Live)
These deliver excellent live data — scores, stats, play-by-play. But they're information tools, not engagement tools. You look up a stat, get the answer, and put the phone down. There's no reason to keep the app open.
Best for: Quick stat lookups and score checks.
Worst for: Sustained engagement during a match.
Useful but not engagingLive Prediction Games (KLASHR)
The newest entrant in the second-screen space. KLASHR is built specifically to be used alongside live sport — AI-powered prediction questions that react to game momentum, fan-submitted predictions (Fan Calls), head-to-head challenges with friends, and Tribes for team-based competition. The game runs in sync with the match, so there's always something to respond to.
Best for: Active, structured engagement during live sport. Proving your sporting instincts.
Worst for: Passive viewing — it demands attention and quick decisions.
Purpose-built for live sportWhy the Second Screen Matters for Sport
The second screen isn't going away. If anything, it's becoming more central to the viewing experience, not less. Younger fans in particular don't distinguish between "watching the game" and "being on their phone during the game" — it's one unified experience.
The question isn't whether fans will use their phones during live sport. It's whether they'll use something designed for that moment — or keep cobbling together an experience from apps that weren't built for it.
Broadcasters are starting to understand this. Interactive overlays, live polls during broadcasts, and companion apps are becoming more common. But most of these efforts feel bolted on — a poll question during halftime, a stat graphic in the corner of the screen.
The opportunity is for a standalone second-screen app that runs alongside any broadcast, on any platform, for any sport. Something that doesn't need a broadcast partnership to work — it just needs the game to be live.
What the Ideal Second Screen App Looks Like
Based on how fans actually behave during live sport, the ideal second-screen app would:
- Sync with the live game — questions and prompts that respond to what's happening right now, not pre-generated content
- Be free to play — removing the financial barrier (and anxiety) of betting
- Enable competition — head-to-head with friends, group competitions, leaderboards
- Allow user-generated content — fans should be able to create predictions, not just consume them
- Work across sports — fans don't watch just one sport, so the app shouldn't cover just one league
- Be quick-fire, not time-consuming — predictions should take seconds, not minutes. You're watching a game, not filling out a form
- Build a profile over time — tracking your prediction accuracy, style, and strengths across sports and matches
This is essentially the blueprint KLASHR is building against. The app covers 15+ leagues — Premier League, NBA, Cricket, F1, UFC, NFL, NRL, AFL, and more — with AI-powered questions that adapt in real time, Fan Calls for user-submitted predictions, head-to-head challenges, Tribes, Gauntlets, and Prediction DNA profiles that map your prediction style over time.
The Bottom Line
The second screen is already a fixture of live sport. Fans are going to have their phones in their hands for the entire match regardless. The question is whether they have something genuinely built for that moment — something that makes watching sport more engaging, more social, and more competitive — or whether they keep scrolling Twitter and checking fantasy scores.
The apps that win the second screen won't be the ones that distract from the game. They'll be the ones that deepen the connection to it.
Your second screen, sorted.
KLASHR is a free live prediction game built for the moments between the moments. Coming soon to 15+ leagues.
