**TriviaRacing turns every question into a race.** Four players. One track. The fastest correct answer pulls your car ahead. Get it wrong or take too long, and you'll watch the leaders disappear toward the finish line. No turn-based waiting. No grinding through hundreds of questions alone. Every match is a head-to-head sprint that wraps in two to eight minutes — perfect for a coffee break or the bus ride home. **HOW IT WORKS** - Pick a race length: Quick (6 rounds), Standard (12 rounds), or Grand Prix (24 rounds) - Get matched with three players near your skill level in seconds - Answer each trivia question — speed and accuracy decide how far your car moves - Cross the finish line first to climb the leaderboards and your rating **FEATURES** - **Real-time multiplayer racing** — see opponents' cars move on the same track as everyone answers - **Skill-based matchmaking** — Glicko-2 rating keeps races competitive - **Three race modes** — short Quick races unlock Standard, which unlocks the long-haul Grand Prix - **Three power-ups per race** — Hint removes two wrong answers, Boost doubles your speed bonus, Freeze halves every rival's speed bonus and shields you from theirs - **Customize your racer** — pick a character, kart body, and wheels - **Daily and all-time leaderboards** — track your rank against players worldwide - **Play anonymously** — no signup, no email required. Link an Apple or Google account later to save your progress across devices. - **Curated trivia bank** — questions across general knowledge, science, history, sports, movies, and more **DESIGNED FOR SHORT SESSIONS** Every race resolves the moment all four players have answered — no waiting out timers. A Quick race finishes in about two minutes. You can play one match while the kettle boils. **FAIR PLAY, BUILT IN** All scoring is server-authoritative. The server picks questions, times answers, and computes points — there is no way to cheat by tampering with the app. New players are protected by beginner-only matches until they find their footing. **NO PLAY BLOCKERS** No energy bars, no lives, no timers blocking play. Every power-up can be earned free through racing — daily rewards and post-race loot drops — so you never have to pay to keep playing. Purchases just top up your stockpile faster. And all cosmetics are purely visual: characters, kart bodies, and wheels never change a race. **WHO IT'S FOR** - Trivia fans who want a faster, more competitive format than solo quiz apps - Casual gamers looking for a five-minute mobile match - Anyone who's ever wanted to settle "who's actually smarter" with a friend

Verdict
The clearest difference is ads: TriviaRacing at none against Detective Diary's shown. TriviaRacing also leads on update cadence (every 3 days vs fortnightly). On price, in-app purchases, monetization model and device support there is nothing between them.
