A private journal

Your taste, decoded

It learns what you love.

Most food apps ask the crowd. Smackerel asks you. As you jot a line about each meal, an on-device model reads your words and sketches your palate over time — three dials for Spice, Salt and Richness, the flavors you gravitate to, the ones you steer clear of, and a running feed of small discoveries like “you go for smoky and charred edges.” No star average. No crowd score. Just a taste fingerprint that’s unmistakably yours, and gets sharper every time you log.


How it works

Three taps and a little patience.

01

Snap it

At the table, tap the camera and take a photo of your meal. Give the dish a name. Save. The whole thing takes a second.

02

Rate it later

A couple of hours later, a gentle reminder asks “how was it?” Tap Love, Good, Mid, Meh or No — right from your lock screen — and add a note if you like.

03

Discover your palate

Behind the scenes, Smackerel reads your notes and grows your taste profile. Open the Palate tab to see who you are at the table.


Private by design

Yours alone. No feed. No ads.

Smackerel collects nothing. There’s no account to make and no server behind it — your meals, notes and photos live on your iPhone and in your own Apple Photos library.

Why I built this

A note from the maker

Smackerel is a personal food journal built for one person: you.

In the early days of the social era — just before Instagram and during the heyday of Foursquare — I built a startup called dish‑on‑it. The idea was simple: take a picture of your food, rate what you ate, and when enough people did that, you’d get a map of what was good, where, and on which day. You could finally find the dish you wanted at the place that made it best, with real photos from real people. Seattle was well represented, and we discovered many new restaurants that made our favorite dishes even better than our tried‑and‑true spots. We had big ideas for where it could go.

Then Instagram arrived, and, well… those ideas went the way of the dodo. We shut it down and moved on.

I loved that app! People used it for two things:

  1. a personal journal of what they ate, how it was, and where — with a photo worth remembering and sharing; and
  2. contributing to a shared pool of knowledge among friends and peers.

I missed that.

Recently, I traveled the world with a backpack and no agenda — made new friends, enjoyed amazing food, boats, buses, trains, hikes, dorms, capsules, nature, history, wine, and, of course, pictures of food. Someone eventually asked me: “Do you have a list of restaurants you like in Vancouver? Specifically Japanese (sushi), Indian, Greek, or Persian?”

It was a reasonable question. We’d cooked for each other. They knew my taste.

I missed that old app — so I built it again.

Smackerel is a re‑imagining of that idea for today’s world: a completely private, no‑accounts, no‑social, no‑ads, no‑noise food journal that gets smarter as it gets to know you. It grows with you. And the best part is: you already have the data. Your photos. Your meals. Your memories.

Upload your food photos, add your rating and tasting notes, and moments later discover your palate — a profile that evolves as you do.

Today, Smackerel is a smart journal. Tomorrow, it may become more. I’m exploring ideas, and I welcome yours. This is a fun project I built for my friends and family, and you’re welcome to use it. If you like it, help me improve it. If you don’t… well, delete it then.

Hello, Smackerel.

Available on iPhone (iOS 26 or later). Yes, it uses on‑device Apple Intelligence with optional escalation to frontier models (Anthropic). Some mackerel were sustainably harmed and enjoyed as sushi in the making of this app.

Good to know

Questions, answered.

What is Smackerel?
A private food journal for iPhone. You photograph a meal, name it, and rate it later. As you add tasting notes, Smackerel builds a personal taste profile — your “taste fingerprint” — showing the flavors you gravitate to and steer clear of. It gets sharper the more you log.
Is it really private?
Yes. No accounts, no Smackerel servers, no analytics, no tracking. Everything stays on your device and your photos stay in your own Apple Photos library. The taste profile is built on-device with Apple Intelligence. Nothing leaves your phone unless you opt in to the optional Claude feature using your own Anthropic API key.
How much does it cost?
Smackerel is free — no ads, no in-app purchases. If you choose to use the optional Claude feature, that runs on your own Anthropic API key, billed to you by Anthropic.
Which iPhones can run it?
iPhone 15 Pro or newer, on iOS 26 or later. The on-device taste engine relies on Apple Intelligence, which needs that hardware.
Will deleting an entry delete my photo?
No. Your photos live in your Apple Photos library; Smackerel only references them and never deletes them. Removing an entry — or the whole app — leaves your photos untouched.
