A day‑by‑day farming simulation tool for Harvest Moon DS that helps you plan your crops, fruit trees and mushrooms to maximise profits.
Inspired by the classic “Profit Planner” for Harvest Moon: Friends of Mineral Town (GBA), this web app brings the same planning power to the DS version.
- Crops (Spring / Summer / Autumn) – 30‑day tables, soil type modifiers, replant toggle, regrowth support.
- Waterfall Field – Super growth (-2 days), crops can be grown all year (120‑day timeline).
- Basements – Normal growth, all‑year farming (120‑day timeline).
- Fruit Trees – Plant once, harvest every few days during their production season (Summer or Fall). Option to mark trees as “already mature” to skip the first year’s growth.
- Mushrooms – Grow in the Mushroom House (no soil effect). Choose harvest size (Small / Medium / Large) which affects initial growth, profit and regrowth cycle. “Already planted” checkbox bypasses the long initial growth.
- Level system – Crops, trees and mushrooms can be levelled up (1‑100). Profit = base price × level² × quantity.
- Day‑by‑day timeline – Each table shows every single day. Icons indicate 🌱 sowing, 🍅 harvest and 🔄 regrowth. If harvest and sowing happen on the same day (replant option), the cell is split with both icons and colours.
- Seasonal colour coding – 30‑day tables have a uniform seasonal background. 120‑day tables are divided into four 30‑day blocks (Spring = green, Summer = yellow, Autumn = orange, Winter = light blue).
- Profit summaries – Per table and a global total that adds all sections.
- Local storage – All your entries are saved automatically in your browser.
- Clear buttons – Clear individual tables or erase all data with one click.
- Add an entry – Select the crop / tree / mushroom, enter quantity, level, sowing day, and any specific options (soil type, replant, harvest size, mature flag).
- View the table – Each row shows a timeline of the whole season/year. Hover over the day numbers to see them clearly (the tables are horizontally scrollable).
- Edit / Delete – Use the ✏️ and 🗑️ buttons next to each entry.
- Check profits – The total profit for the section appears below the table, and the global summary at the bottom updates automatically.
- Clear data – Use the yellow “Clear table” buttons or the red “Clear All Data” button in the global summary.
Note: For crops that naturally regrow (e.g., Cucumber, Tomato, Pineapple), the “Replant after harvest” checkbox is disabled – regrowth is always more efficient.
The tool respects all game data from the excellent Ushi No Tane Harvest Moon DS guide:
- Main Guide
- Seasonal Crops
- Mushroom House
- Fruit Trees
- Field Types (Slow / Normal / Fast / Super)
- Crop Leveling
- Basement System
