QuantFloor: Quant Math Game

Train the mental math you need when the clock is running.

QuantFloor turns quant interview practice into focused 90-second rounds. Work through arithmetic, percentages, fractions, estimation, probability, and expected value, then review your accuracy, speed, and weakest topic at the closing bell.

Built for focused practice:

- Adaptive difficulty that responds to your answers
- Score and streak feedback during every run
- Bull and Bear coaches with different personalities
- A concise debrief after each round
- A reduced-motion setting

Private by design:

Your questions, answers, scores, and coaching stay on your Android device. QuantFloor does not require an account, advertising ID, subscription, or API key.

Before your first run, QuantFloor downloads a public Qwen3 0.6B model and verifies it on your device. Coaching then runs locally through Google LiteRT-LM without cloud inference. You can delete the model at any time from Settings.

QuantFloor is practice software, not financial advice or a trading platform.
