CoffeeStamp Cup Number Album

Snap the cup sticker and collect your daily coffee pickup numbers into a 000-999 album.

Problem: People who buy Luckin or Starbucks daily glance at the pickup number on the cup sticker. It is a free daily number lottery, but once the cup is thrown away the number is gone, and no app helps users keep them. Coffee apps only handle ordering, not collecting.
Solution: Use the phone camera to photograph the cup sticker, OCR the brand and pickup number, automatically cut the number sticker out of the photo, straighten it and add a white border, then light up the matching cell in a 000-999 album. Every cell must be unlocked by a real photo, never typed in; support multiple brand sticker templates and album sharing.
Users: Young users who drink chain coffee such as Luckin or Starbucks daily and enjoy collecting and sharing small wins.
MVP: Cup sticker capture with brand + pickup number OCR; sticker cutout and straightening; 000-999 album UI; local storage and share cards; start with 2-3 brands like Luckin and Starbucks.
Revenue: Free base album with in-app purchase for unlimited brand templates, HD export and cloud sync; or co-branded campaigns with coffee brands.
Why now: Coffee purchase frequency is high in China and the cup numbers are inherently random, while mobile OCR and cutout are mature enough for an indie dev to ship a shareable little app in a few weeks.
