FORTUNE CITY → FUTARI

Your Fortune City data can come with you

Fortune City turns budgeting into a game; to move those records to Futari and log together, a screenshot + ChatGPT turns them into a CSV.

Why Futari

  • Build it together, not each alone

    Fortune City is one person’s city; Futari is one ledger two people share, where every shared expense is logged once and seen by both.

  • Splitting and settling built in

    Half, by ratio, each their own, or one covers it — once you choose, who owes whom is settled automatically.

  • Take your records with you

    Export to CSV whenever you want to leave; the data is yours, not locked inside one city.

Three steps

  1. Screenshot the transactions you want to move in Fortune City (full how-to below).
  2. Turn the screenshots into a CSV with ChatGPT — a copy-ready prompt is below.
  3. Upload the CSV here, preview it, and create an account to finish the import.

No CSV export? Use screenshots

If your old app has no CSV export, you can screenshot your records and have ChatGPT turn them into a CSV to upload. The free ChatGPT plan works.

  1. In your old app, scroll your transaction list and take phone screenshots (5–10 is a good range to cover the period you want to move).
  2. Open ChatGPT, upload all the screenshots at once, and paste the prompt below.
  3. Copy the whole ```csv code block ChatGPT returns and save it as xxx.csv in any plain-text editor.
  4. Come back here, upload that csv, preview it, and create an account to finish the import.
Prompt to paste into ChatGPT
You are my bookkeeping data assistant. I will upload screenshots from a budgeting app. Please turn every transaction shown into CSV format.

Requirements:
- The first CSV row is the header: date,category,amount,description,currency,kind
- Use YYYY-MM-DD for date; if a screenshot only shows month/day (e.g. 5/30), assume the current year
- Use a positive integer for amount (no minus sign, no decimals); if it was shown as an expense or in red / with a minus sign, set kind to "expense"; if it was income or in green, set kind to "income"
- Keep the original category text from the screenshot (Chinese or English, as-is)
- Keep the merchant name or note text in description; leave it blank if there is none
- Use an ISO 4217 three-letter code for currency (TWD / USD / JPY / CNY…); default to TWD if the screenshot does not show one
- If the same transaction (same date + amount + description) appears across multiple screenshots, keep only one
- Output the CSV inside a single ```csv code block only, with no explanatory text before or after

I will upload the screenshots once you confirm.
The CSV will look like this
date,category,amount,description,currency,kind
2026-05-30,Food,150,Starbucks,TWD,expense
2026-05-30,Salary,50000,May,TWD,income

Non-TWD rows import at their raw number first; you can adjust the conversion per row after import. Duplicates of the same entry (same date + amount + description) are dropped automatically.

Frequently asked

Fortune City has no export — can my data really move?
Yes. Screenshot the transaction view and have ChatGPT turn it into a CSV, then upload — full steps and a copy-ready prompt are below, and the free ChatGPT plan works.
How many screenshots?
5–10 is a good range; scroll to cover the period you want to move. Duplicates of the same entry are dropped automatically.
Does importing cost anything?
Futari is completely free, with no hidden charges.
Does my game progress come over too?
No — what moves is your bookkeeping data (date, amount, category); the game stays in the original app. Futari focuses on the shared ledger itself.
