In TestFlight · iPhone & Apple Watch

A pet that lives and dies by your habits.

Your steps, workouts and sleep from Apple Health become a creature that thrives when you move — and in Mortal Mode can genuinely die.

You're not taking care of the pet. You're taking care of yourself. The pet is living proof.

$19.99 once, after a 21-day trial. No subscription — your health data never leaves your phone.

This is Flamy. One of four companions.

How it works

Your day is its food.

Apple Health syncs automatically. Your real activity drops up to three meals a day — drag one onto your pet and it eats from your hand.

  1. An apple

    for hitting your steps

  2. A banana

    for a real workout

  3. A pear

    for a good night's sleep

Food doesn't stockpile. Tomorrow has to be earned again — your consistency puts food on its table.

Watch it evolve — for about a year

Ten stages, unlocked only through real activity. Progress is the pet, not a chart.

Three promises, your call

Add up to three small quests — a walk, a stretch, a glass of water. Skip one and nothing is lost. A nudge, never a punishment.

What it reads

Four signals. One creature.

Computed on your device. The numbers are the input — the pet is the output.

  • HRV, resting heart rate, sleep and BMI — one living score.

  • Steps, distance and workouts, straight from Apple Health.

  • A good night earns a pear. Rest is food here.

  • A quiet day is rest, not failure. Nothing turns red.

The stake

It can actually die. That is the point.

We all abandon streak counters and swipe away badges, because there is no emotional cost to quitting.

Mortal Mode gives it one. Miss too many days and your pet is gone, with a memorial in your timeline.

Death is part of the story — sadness, not shame. Prefer not to carry it? Immortal Mode removes permanent loss. You choose at setup, in a minute.

  • 1 hungry day — a warning. Your pet is quiet, and it misses you.
  • 2 in a row — it costs a life.
  • 3 perfect days — you win one back. You can always come back.

The companion

It has moods. It reacts. It remembers. It never judges.

Every morning, a letter

Add the optional on-device brain and your pet writes you a short letter about yesterday, in its own voice.

“I missed seeing you today.”

A companion, never “you walked only 4,123 steps”.

Every word is generated on your phone. Skip it and the pet still reacts and celebrates — the app is complete without it.

Your journey, visible

A winding path of every day with your pet — glowing active days, level-up milestones, streak badges at 7, 30 and 100. Tap any day to replay it.

Four companions

Flamy, Splosh, Mossy and Blobby — each hand-crafted and animated. More arrive later as optional cosmetic packs.

Platforms

Where your pet actually lives.

Honestly — no badge that goes nowhere.

  • iPhone

    Ships now

    The first-class surface — HealthKit, widgets, Live Activity, Dynamic Island.

    • Apple Health: steps, distance, workouts, sleep
    • Lock Screen widget — portrait, level, hearts, streak
    • Live Activity & Dynamic Island
  • Apple Watch

    Ships now

    A real watch app, not a mirror. Your pet lives on your wrist — and you feed it from there.

    • The pet, animated, on the watch
    • Complications on your watch face
    • Feed your pet from your wrist
  • Android

    In development

    The Health Connect plumbing is real, but it isn't shipped — and we won't promise a date we don't have.

    • Health Connect integration exists in code
    • Not available yet — no release date
  • Web

    Not planned

    No web app, and none planned. Your pet lives on the device that knows your day. This page is the only web surface.

The app ships in English, Czech, German, Spanish and French. This website is English-only for now.

Privacy

Private by architecture, not by promise.

Most apps promise privacy in a policy. We enforce it in the architecture: no server ever sees your health data. Steps, sleep, coaching, even the pet's letter — all computed on your device. No account, nothing to leak.

The AI runs on your phone
A compact open model (Gemma, via llama.cpp), downloaded once and run locally. No cloud, no per-message cost.
No account, ever
Nothing to sign up for. Game state backs up through iCloud — yours, not ours.
The honest exception
One small server handles push and redacted crash reports. It never sees a health value — and you can turn it off.

Pricing

Pay once. Own it forever.

Like games used to work.

21 days free. No credit card.

$19.99 once

One purchase unlocks everything, forever: all four pets, every mechanic, the coaching, the optional AI brain.

  • No subscription
  • No ads
  • No account
  • No feature held hostage

Optional cosmetic packs ($2.99–4.99) arrive later and fund development. The base app is complete without them — always.

Questions, answered straight.

Is this really not a subscription?

Really. $19.99 once, after a 21-day trial. Cosmetic packs are one-time too. If we ever changed it, everyone who paid keeps what they bought — but we don't intend to.

Does my health data leave my device?

No — by architecture, not policy. No cloud AI, no account, no server that processes your health data. Our small server only ever gets a push token and redacted crash reports, which you can turn off.

How does the AI work without a cloud?

You optionally download a compact open model (~3 GB, Wi-Fi) that runs on your phone. Older phones skip it — the pet's built-in personality still reacts and celebrates. Complete either way.

Can my pet really die?

In Mortal Mode, yes — miss too many days and it's gone, with a memorial in your timeline. Immortal Mode removes permanent loss; the pet still grows. You choose at setup.

Do I need an Apple Watch?

No. The iPhone app is complete on its own. The watch app is a genuine companion if you have one: your pet on your wrist, complications, feeding from there.

When is Android coming?

We don't know yet, and we'd rather say so. The Health Connect integration exists in code, but Android isn't shipped and whether it's a launch requirement is still open. When there's a date, this page will carry it.

What if I don't use Apple Health?

You can log activity manually. Garmin, Oura and Fitbit are on the roadmap, but not built yet.

Your pet is waiting.

In TestFlight, not launched publicly yet. Leave a line and we'll tell you the moment it is — that's the whole list.

Opens your own email app. No form, no tracker, no mailing-list company — just lukas.chylik@gmail.com.

Not here to raise a pet?

The problem, the wedge, the unit economics, the moat, and an honest status report — written for angels and investors, not for marketing.
