The pantry tracker that roasts you before things expire. Four tones, four characters, all on-device. Stop forgetting what you bought.
How many of the things you bought have you actually finished?
Buy-Bye is an inventory app for everything you've bought and forgotten. It's not just an expiration reminder — it'll roast you, comfort you, or coolly report the numbers, depending on which of four voices you choose to live with.
## Why we made this
The skincare in the corner of your shelf. The pantry stuff you'll "definitely use this week." The half-finished bottle of olive oil from last winter. You buy with optimism; you forget just as fast.
We didn't build Buy-Bye to be another reminder. We built it so you can have a conversation with your own buying habits. Every item ages, gets a nudge, and eventually says its goodbye.
## What you can do
• Snap a package photo — auto-fills name and expiration date
• Scan a barcode — pulls product info from OpenFoodFacts
• Morning / evening routines with streak tracking
• Waste log — see how much you've actually thrown away in cash
• Per-item view: days left, days since opened, expected uses
• Custom categories and per-item replacement cycles
• Local notifications before things expire (timing customisable)
## Four voices, four characters
Pick one, and it sets the voice for everything:
• Sharp: "babe, no. you literally just bought one."
• Gentle: "don't worry, we'll get through them one by one."
• Calm: "12 items. 3 expiring within 7 days."
• Cute: "the little ones are waiting for you."
Each character has its own art, expressions, and idle / walk / sleep / celebrate animations. Your cupboard now has residents.
## Fully on-device
Buy-Bye **collects no data**. No account, no cloud, no tracking, no ads, no analytics SDK.
Everything you enter lives only on your phone. Package photos are processed by your device's built-in ML Kit / Vision — they're never uploaded.
See in-app Settings or our Privacy Policy for full details.
## Three languages
Traditional Chinese / English / Japanese — switch live in Settings.
Buy-Bye is the first product from Sumine Town (隅眠町), an IP line by Nookori Works (小隅作室).
