Nukoket - Doujin Event Helper

Nukoket is a free helper app for doujin events, comic markets and fan conventions — whether you are selling at your own booth or going around buying from circles. It works fully offline, so it keeps going even when the hall's mobile signal doesn't.

FOR EXHIBITORS — SELL AT YOUR BOOTH

■ Products and sets
Register each item with a picture, price and how many you brought. Make sets ("new book + postcard") at their own price; selling a set takes each item out of stock.

■ Tap to record sales
Tap item tiles to build an order and record it. Remaining stock updates instantly, and a sale can be undone.

■ Customer-facing register screen
Big pictures and prices your customers can read. Tap the bills you received and the change is calculated for you. Stock counts stay hidden — the item only shows how many are left when fewer than 10 remain, and sold-out items can't be added.

■ Sample copies and gifts
Record copies given to the organizers or friends separately: they leave stock but don't count as sales.

■ Change float and cash check
Count the cash you start with bill by bill, then compare the cash at the end with recorded sales to see any difference.

■ Packing checklist
Standard items (change, price tags, table cloth…) in one tap, plus your products with the quantities to bring.

■ Summary and CSV
Revenue, items sold and sell-through per product. Export sales lines or product totals as CSV.

■ Copy from last time
Start the next event with the same products, sets, checklist and change float.

FOR BUYERS — SHOP WITHOUT MISSING ANYTHING

■ Circles and wish list
Add the circles you want to visit with space number, SNS link and menu picture, and the items you want with price and priority (must / want / if budget allows).

■ Event day checklist
Circles in space-number order with a route of the ones left. Tick off what you bought, or mark items sold out or skipped.

■ Venue map with pins
Import up to 5 pages of the venue map and pin your circles on it. Pins are colored by what is still to buy there.

■ Budget
See your planned total, must-buy total and what you have spent against your budget.

■ Errands for friends
Items friends asked you to buy are kept apart from your own budget, with totals per friend.

■ Add from X (Twitter) or Pixiv
Share a post, link or picture to Nukoket and it becomes a circle or a wish-list item. The space number and author are filled in when they can be read from the post.

FOR EVERYONE

• Currency per event — great for events abroad
• 9 languages, switchable inside the app (handy when talking with customers abroad)
• Back up everything (events, pictures, settings) to one file and restore it on a new phone

PRIVACY AND PRICE
All features are free. Your data stays on your device and is never uploaded. A small ad banner (Google AdMob) is shown on some screens, but never on the selling, register or event-day screens. If Nukoket helps you, you can support development with an optional tip.
