Pick two to four open bottles, or let the app pick. Someone else pours and sees which glass is which. You taste each one without names, give it a verdict, then guess. The app keeps score, and every glass is saved as a pour.
Infinity bottle New
One bottle for the ends of the others.
Top it up with the last of a good bottle. The app tracks what went in, the proof when every proof is known, and roughly what it tastes like now. Pour from it like any bottle. It counts as one.
Also new: recaps of the quarter and the year, and bottles that remember the day they were opened. All free.
How it works
Built for the shelf you actually have.
No feed, no scores, no social network. A record of what you own and what you thought of it, and a quiet opinion about what to open next.
Scan a bottle
Point the camera at the label.
The label is read on your phone and matched to a shared catalog, with proof, age, style and the flavors reviewers usually find. Not in the catalog? Add it by hand. In a store, Should I buy it? checks a bottle against your own palate and what's already on your shelf.

Your shelf
Every bottle, and how much is left.
Fill levels, when you last poured it, what it cost. Chips for wheated, high rye, barrel proof, bottled-in-bond, single barrel and allocated, drawn from the catalog's facts rather than guessed from the name. Store picks and batch numbers live on the bottle, and finished bottles stay in your history.

Tonight
What should I open?
One screen for the question you have at nine o'clock. It leans on what you've loved, what you haven't touched in a while, and what's already open. It also tells you which bottle is running lowest.
Log a pour
A verdict and the flavors you got.
A few taps: love, like, meh or no, the flavors you actually found, a note, a photo if you like. The bottle's fill and last-poured date update on their own.

Palate read Reserve
What you like, from what you've poured.
Over time the app builds a picture of your palate from your own verdicts, not from anyone's scores: the flavors you keep confirming, and an honest read of the whole shelf. On iPhones with Apple Intelligence it writes that read, and a short note on each bottle, on the phone. Nothing is sent anywhere.
Captions Reserve
When a pour deserves a post.
The app drafts a caption from the facts of that pour. Edit it, share it wherever you like, or don't. The app never posts on its own.
Saturday pour: Weller Special Reserve, 90 proof. Wheated and soft. Verdict: love.
Privacy
Your shelf is yours.
Your bottles, notes and photos are stored on your iPhone and, if you use iCloud, in your own private iCloud. The developer can't see your shelf, and has no wish to.
No account. Open it and start.
No ads, no analytics, no tracking. Nothing sold, because nothing is collected.
On-device. Label reading and the written notes run on the phone.
Follows you. A new iPhone on the same iCloud gets the whole shelf back.
Who made this
One person and a shelf.

I'm Paul Cobb. I drink bourbon, and I wanted an app that remembered what I'd poured and what I thought of it, without asking for an account or selling what it learned. I couldn't find one, so I built it, and kept everything on the phone.

Questions
Asked, answered.
Is it free?
Free to download and genuinely useful free: up to 15 bottles, 5 label scans, manual add, catalog search, logging, Tonight and export. Reserve lifts the cap, makes scanning unlimited, and adds the palate read, the written note on each bottle and drafted captions: $3.99 a month, $24.99 a year with a 7-day free trial, or $59.99 once. Whatever you add is yours on any plan; nothing is ever hidden or deleted. No account, no ads either way.
Do I need an account?
No. The shared catalog downloads anonymously the first time you open the app, and everything you add stays on your phone and in your iCloud.
Does it work without Apple Intelligence?
Yes. The written notes and shelf reads need an iPhone that supports Apple Intelligence (iPhone 15 Pro or newer) with it turned on. On any other iPhone running iOS 26 or later, the app shows the plain facts instead, and scanning, the shelf, Tonight and logging all work the same.
Is there an Android version?
No. It's built on Apple's on-device tools, which is a large part of how it keeps your data on your phone. iPhone only.
What data do you collect?
None. The App Store label says "Data Not Collected". The catalog request carries no account and no identifier, and this website runs no analytics and sets no cookies.
Pour something. Write it down.
Free to start on iPhone. No account, no ads, nothing leaves your phone.
