How it works

From sale to profit in three steps

No sign-up, no setup wizard. Record your first sale the moment the app opens.

1

Record the sale

Item name and price — that's it. Shipping, packaging and fees are pre-filled from your previous sales, or read straight off a screenshot with on-device OCR.

2

Profit appears instantly

The platform's fee rate is applied and snapshotted, costs are deducted, and your real profit shows in green — or a loss in red. No spreadsheet, no mental math.

3

Watch the month add up

The dashboard shows this month's earnings at a glance, with profit-trend charts and a per-marketplace breakdown in the monthly report.

Profit engine

The profit you see is the profit you keep

Most sellers overestimate what they earn because fees and costs hide in the fine print. Urilog deducts every cost the moment you record a sale, using the fee rate of the marketplace you sold on.

  • Built-in fee rates for Mercari, Rakuma, Yahoo! Auctions and Yahoo! Flea Market — fully editable
  • Rate snapshots — editing a fee rate later never rewrites your history
  • Profit in green, loss in red — always, everywhere in the app
Screenshot OCR

Screenshot in, transaction out

Take a screenshot of the marketplace's transaction screen and Urilog reads the item name and price for you. Text recognition runs entirely on your device — the image never goes anywhere.

  • On-device recognition — no upload, works offline
  • Name and price auto-filled into the quick-entry form
  • Attach photos of items and receipts, stored locally
Tax season

確定申告-ready, all year round

When tax season comes, a year of flea-market activity is one export away. Sales, expenses and profit go out as CSV — in a generic layout or accounting-software-friendly formats.

  • Tax-ready CSV export of sales, expenses and profit
  • Expense & inventory tracking — sourcing, packaging materials, shipping
  • Full backup & restore — switch phones without losing a single sale

FAQ

Questions, answered

Is my sales data uploaded anywhere?
No. Urilog is offline by design — it performs no network communication at all. Every transaction, item, expense and setting is stored only in a local database on your device. There is no account, no server and no cloud. The full details are in the privacy policy.
Which marketplaces does Urilog support?
Fee rates for Mercari, Rakuma, Yahoo! Auctions and Yahoo! Flea Market (PayPay Flea Market) are built in, and every rate is editable — you can also add your own platforms. The rate in effect is snapshotted on each sale, so editing a rate later never changes your history.
Is Urilog free? Is there a subscription?
The current release is free with every feature unlocked. There is no subscription and no ads — if a premium unlock is ever introduced, it will be a one-time purchase.
Can it help with my tax return (確定申告)?
Yes. Urilog exports your sales, expenses and profit as CSV in a generic format and in accounting-software-friendly layouts, so a year of flea-market activity is ready for tax season. The figures are based on the data and fee rates you enter, so verify them against official marketplace statements before filing.
What happens to my data when I switch phones?
Urilog can export a full backup file that you transfer yourself (AirDrop, cloud drive, cable) and restore on the new device. Because all data lives on the device, uninstalling the app without a backup deletes it.

Stop guessing what you actually earned.

Urilog is coming soon to the App Store and Google Play. Until then, say hello — we'd love to hear from fellow sellers.
