ChubbyPuppy — The fitness app that's secretly a puppy

How it works

Three tiny habits. One very happy puppy.

Welcome to fitness that doesn't feel like fitness.

🐶 Step 1

Pick your buddy

Nine breeds, all included. Give them a name. They're a little chubby right now — you're going to fix that together.

📸 Step 2

Snap. Judge. Feed.

Point your camera at a meal. AI reads the macros in seconds, Judge Paws hands down a verdict, and your puppy chows down. Protein wins. Sugar gets convicted.

🚶 Step 3

Move a little, morph a lot

Steps, workouts and weight flow in from Apple Health. Every walk earns XP, and every kilo you lose makes your puppy leaner — live, in 3D.

⚖️ The Snack Court

Every meal goes on trial.

Meet Judge Paws. Scan a meal and the court stamps a verdict based on the macros: protein-packed plates get crowned, sugar bombs get convicted. The court judges the food — never you.

👑 PROTEIN ROYALTY+25 Treat XP. The court bows.
🛡️ RESPECTABLE+10 XP. Solid. Dependable.
🤨 SUSThe court has questions.
🚨 TREAT CRIMEThe court will remember this.

Try it → pick a dish, then summon the judge.

🏠 The Den

Not a dashboard. A room.

Everything in your puppy's Den is a real stat you can poke. Everything squishes. Everything bursts. Go on, try the cards.

🪟

A window with weather

The sky in the Den goes dawn, day, dusk and night with you. The puppy never hides its face — it's always happy to see you.

🐕

A 3D puppy that morphs

Your real weight drives their body shape. Lose a kilo and watch them slim down. Scrub the chart and their body rewinds with it.

📜

Daily quests + a chest

Walk 8,000 steps. Bank 100g protein. Log 2 meals. Finish all three and a chest pops open with rarity-rolled gear.

🎒

Backpack & auras

Hats, collars, capes, boots and glowing particle auras. Yes, your corgi can wear a Galaxy Aura. Yes, it's magnificent.

🏆

A trophy case

17 badges to earn: First Kilo Down, Weekly Warrior, Protein Pro, Puppy Love… Pin your favourites to the shelf.

📈

Path of Paws

One clean line of your weight, plus a day-by-day ledger of burned vs eaten. No spreadsheets. No shame.

💬

A coach with personality

Chat with Napawleon, Cleocatra or Sigmund Flead. They know your real stats and run on-device with Apple Intelligence.

⌚

Watch, widgets & Live Activity

Your puppy cheers you on from your wrist, your Home Screen and the Dynamic Island mid-workout.

💌

Gentle nudges

Forget to log for a while and your puppy says hi — in character. Never spammy. Never shamey.

The Den with Biscuit awakened as a Wolf Cub

🏛️ Legendary Forms

Every kilo wakes something ancient.

Hit a weight-loss milestone and your puppy can awaken as a legend. Not a costume: a whole new creature living in your Den, until you decide to come back to your best friend. Every legend comes with Premium, but you still have to earn it: paying never skips a milestone.

“I have a calorie corgi now.”

Every win comes with a share card. Down a kilo? “We are UNRECOGNIZABLE.” Logged a treat? “Biscuit saw the snack and will testify.” Send it. They'll text back asking what app this is.

❓ FAQ

Questions, sniffed out.

Is this actually good for me, or just cute?›

Both. ChubbyPuppy is built around one idea: more protein, fewer sugar and carbs, a little more movement. Meals log straight to Apple Health, XP scales logarithmically so you can't overtrain your way to more points, and the puppy's body tracks your real weight.

Do I need an Apple Watch?›

Nope. Any iPhone with Apple Health does the job. The Watch app, complications and Smart Stack widget are a bonus for people who have one.

What does the AI actually see?›

With your consent, a meal photo is sent securely to Google's AI through Firebase for nutrition estimates. Camera/GPS metadata is removed, and Health history is not attached. Technical service information is still processed; you can turn future uploads off. The coach and Judge Paws run on-device with Apple Intelligence on supported iPhones. Details are in our privacy policy.

What happens if I miss a day?›

Your puppy gets a bit hungry and might say hi. Streaks have a grace day, nobody gets shamed, and the Den is exactly as happy to see you tomorrow.

Is there a free version?›

No. You can walk through onboarding and pick your buddy for free, but the Den opens with Premium. Annual starts with a 3-day free trial for eligible customers, and every plan can be cancelled any time in your App Store settings.

When and where does it launch?›

September 2026 on the App Store, for iPhone running iOS 26. Android isn't on the leash yet. Join the pack and we'll bark when it's live.

Time for both of you to come home.

Your activity makes them lean. Their journey makes yours easier. Be first in line when the Den opens.

One email when we launch. Zero spam. Pinky paw promise.
