Lie or Legend — a full-stack trivia game ecosystem.

Mobile App

Fast rounds, smart game modes and sticky replay loops.

The mobile app is designed around short, addictive judgment moments: read a claim, decide whether it is a lie or a legend, then see exactly where the truth turns.

Multiple game modes

Daily Classic, Extra Classic, Myth Mix, Double Bluff, Revenge rounds and shared challenges operate from one unified game engine.

Challenge a friend

Players can create shareable challenge links and designed result cards built for social sharing and re-entry.

Retention systems

XP, levels, streaks, perfect games, rewards and game balances turn short rounds into a long-term loop.

Premium monetization

Classic Pass, RevenueCat purchases, rewarded ads and ad removal are wired into the gameplay economy.

App Screens

Dashboard + Admin Cockpit

Content operations without chaos.

The dashboard is the control room behind the app. It handles daily packs, extra quest inventory, Double Bluff pairs, statement pools, player operations and emergency content controls.

Daily operations Plan, review and publish Daily Quest Packs, Extra Packs and Double Bluff content from a dedicated cockpit.
Human-in-the-loop review AI helps generate and verify content, while final approval stays controlled by an admin review queue.
Player management User plans, extra plays, support actions and emergency controls are managed from admin workflows.
Content safety controls Verification status, quality scores, duplicate decisions and emergency disable options reduce content risk.

AI-Powered Generation System

AI generation with human taste and verification control.

Lie or Legend does not rely on random content dumping. The system is built around AI-assisted creation, duplicate detection, verification guards and human approval before publication.

Lie or Legend AI powered duplicate checker system
01

Generate

Age-group aware prompts produce candidate statements, explanations and answer logic.

02

Guard

Duplicate checks, semantic scans and quality rules catch weak or repeated content before it ships.

03

Verify

AI verification guards check answer polarity, issue type, confidence and correction potential.

04

Review

Drafts move through a dashboard where content can be approved, rejected, corrected or disabled.

05

Publish

Approved packs are scheduled into daily, extra, Myth Mix and Double Bluff game flows.

Backend + Server Stack

The app runs on a real product backend — not a fragile prototype.

Sessions, user profiles, purchases, shared challenges, daily packs, support requests, admin tooling and autopilot jobs are handled by a structured API and database layer.

Website + Launch Layer

The app also has a polished public-facing ecosystem.

The product website supports store downloads, invite links, support, privacy pages and brand storytelling. Challenge links can send friends to the right platform while keeping the app experience clean.
