Animal Crossing Turnip Price Predictor Utility
Overview
A high-performance, single-file browser utility designed to help players forecast turnip prices in the popular life-simulation game. This tool serves as a lightweight, privacy-focused alternative to complex spreadsheets or external web services.
Technical Implementation Rules
- Single File: All HTML, CSS (Tailwind CDN), and Vanilla JS must exist within one
.htmlfile. - Storage Constraint: STRICTLY NO usage of
localStorage,sessionStorage, or Cookies. All data must exist in volatile runtime memory. - Responsiveness: Fluid layout that adjusts from mobile grid to desktop sidebar/main view.
- UI Constraints: Vibrant, clean light-mode only. No dark mode toggles. Soft shadows, rounded borders, and crisp, modern typography (Sans Serif).
Feature List
- Dynamic Input Grid: A clean 2-column list (Monday to Saturday) with AM/PM fields.
- Pattern Calculator: A processing engine that evaluates input against known game patterns (Fluctuating, Small Spike, Large Spike, Decreasing).
- Probability Visualization: A simple, high-contrast table displaying the "Minimum" and "Maximum" price ranges for each upcoming time block.
- Instructional Overlays: Custom modals explaining how to input values (e.g., "Buy Price" and daily entries).
- Instant Calculation: Real-time feedback via JS listeners; results update immediately as digits are typed (debounced by 300ms).
UI Layout Design
- Header: Clean, centered, titled "Animal Crossing Turnip Price Predictor." Sub-heading: "Maximize your island profit potential."
- Main Tool Area:
- Top Section: Input for Sunday 'Buy Price'.
- Mid Section: A responsive grid of 12 input boxes for AM/PM prices.
- Action Area: A 'Clear Data' button that resets the state without reloading the page.
- Results Section:
- A summary card highlighting the "Highest Likely Sell Price."
- A table showing the projected price range for all upcoming slots.
Design Aesthetic
- Color Palette:
- Primary: Soft Sky Blue (#E0F2FE) for headers and backgrounds.
- Accent: Vibrant Leaf Green (#22C55E) for call-to-action buttons.
- Text: Dark Slate (#1E293B) for readability.
- Cards: White (#FFFFFF) with a subtle, soft drop-shadow (
box-shadow: 0 4px 6px -1px rgba(0,0,0,0.1)).
- Transitions: All UI interactions (button hovers, modal visibility) must use CSS
transition: all 0.3s ease-in-outfor a "premium SaaS" feel.
SEO & Performance Strategy
- SEO: Use semantic HTML5 (
<main>,<section>,<h1>,<table>) for accessibility and search engine indexing. - Performance: No external dependencies other than Tailwind CSS and a lightweight charting library (if needed via CDN). The code must execute instantly, ensuring a sub-100ms "Time to Interactive".

Frequently Asked Questions
Everything you need to know about using this application.
How does this Animal Crossing turnip price predictor work?
This tool utilizes established mathematical models based on the game's internal algorithms to project turnip price trends. By inputting your current and past daily prices, the application analyzes the potential pattern—such as fluctuating, decreasing, or spike patterns—to forecast the range of your future prices. The algorithm refines its predictions as you provide more data points throughout the week. While no prediction is 100% guaranteed, the calculator narrows down the probabilities, allowing you to make informed decisions about when to sell your turnips for maximum profit.
Can I save my input data to revisit later?
This application operates entirely in your browser's memory for privacy and security. Consequently, it does not use cookies, local storage, or server-side databases. If you refresh the page or close your browser tab, the data currently entered will be cleared. To manage your tracking effectively without storage, we recommend keeping the browser tab open throughout the week or simply documenting your trends externally if you prefer to come back later. This ensures your session remains fast, lightweight, and completely private.
Why are my predictions changing when I add more prices?
Predictive models for the game are dynamic and probabilistic. When you start the week with very little data, the tool calculates all statistically possible patterns. As you input your morning and afternoon prices, the algorithm effectively 'rules out' unlikely patterns. This continuous refinement is the core function of the tool. Every new price you enter increases the accuracy of the prediction. If the model seems to shift significantly, it simply means your data has provided enough evidence to eliminate previously plausible outcomes.
What if I miss a day of checking my turnip prices?
Missing a few data points does not break the calculation, although it may broaden the range of possible outcomes. The tool is designed to work with partial data; you simply leave the missing fields blank and the algorithm will provide a prediction based on the remaining input. While your accuracy might decrease slightly, the tool remains a highly effective way to estimate your profit margins even with sporadic entries. Simply provide as much data as you have available to get the best possible forecast.
