Overview

Socials:

LearnClash is a competitive learning app where you master any topic by challenging others to 1v1 quiz duels. Pick any subject, from Quantum Physics to Pop Culture, and LearnClash AI generates fresh questions on demand, served at a difficulty matched to your skill. Built-in spaced repetition makes sure you actually keep what you learn instead of playing and forgetting.

How LearnClash works:

- Pick any topic or request a brand new one, with no fixed question bank
- Play asynchronous 1v1 duels: 6 rounds of 3 questions (18 total), 45 seconds each, up to 72 hours per turn
- Questions adapt to your level as your rating changes
- An ELO rating system ranks players and matches you with opponents of similar skill
- Climb 8 competitive tiers from Iron all the way to Phoenix

What makes LearnClash different:

- Spaced repetition in both modes: every question is scheduled for review (Learning, Known, Mastered) so knowledge sticks long term
- In-duel power-ups: turn the tide with 50:50, Peek, Ask the Crowd, and Double Down for double points
- Solo mode: train at your own pace with 9-question sessions, full XP and streak credit, no rating at stake
- Per-topic Mastery: watch your knowledge grow with a Mastery score for every topic you play
- Cross-language duels: each player sees questions in their own language (English, German, French, Spanish)
- Clash Chat: an AI tutor that explains why an answer was wrong and takes your follow-up questions
- iOS Live Activities, friends with head-to-head records, daily quests, and streaks

Pricing:

- Free forever with no ads in any tier: unlimited daily duels and all 8 ELO tiers
- Premium ($7.99/month, or $59.99/year at $5.00/month with a 7-day free trial) adds a 100-topic library, unlimited Solo sessions, unlimited Clash Chat, advanced statistics, topic rerolls, and more

Who it is for:

Love it! So far it looks like a hybrid of educative.io (path, text format, practice with mistakes correction after) duolingo (on the practice part) based on the user experience and I personally like both

LearnClash is a 1v1 quiz duel app for iOS and Android. You pick any topic, the AI generates questions at three difficulty levels, and you compete against friends or matched opponents in 18-question duels. An 8-tier ELO system ranks you from Iron (100) to Phoenix (2400+), and every question you answer feeds into spaced repetition so knowledge sticks. Free with zero ads.

How does LearnClash generate questions using AI?

David Moosmann

🛠️ 1 tool 🙏 1 karma

wrote:

You type a topic (anything from "Cold War espionage" to "Taylor Swift discography") and the AI creates fresh multiple-choice questions at easy, medium, or hard difficulty. Questions are calibrated to your skill level. No two sessions repeat the same set, so you always face new material.

Can I challenge my friends directly on LearnClash?

David Moosmann

🛠️ 1 tool 🙏 1 karma

wrote:

Yes. Send a challenge link, your friend taps it, picks a topic, and you're matched for a turn-based 1v1 duel. Each duel has 6 rounds with 3 questions per round (18 total), 45 seconds per question. You have 48 hours per turn, so you play on your own schedule.

What is the Spaced Repetition System (SRS) used in LearnClash?

David Moosmann

🛠️ 1 tool 🙏 1 karma

wrote:

Every question you answer in any game mode (duels, practice, or topic-locked matches) enters a 3-stage review cycle: Learning, Known, Mastered. Get a question wrong and it drops one stage. Answer correctly twice across 90 days and it's permanently retained. You build lasting knowledge without needing a separate flashcard app.

How does ELO matchmaking work in LearnClash?

David Moosmann

🛠️ 1 tool 🙏 1 karma

wrote:

LearnClash uses an ELO rating system adapted from competitive chess. New players start at ELO 800 (Bronze I) with a K-factor of 40, so early matches shift your rating quickly. After 10 duels the K-factor drops to 20. The system pairs you with opponents within a similar rating range across 8 tiers: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, and Phoenix.
