Your pet eats your workouts.
Skip leg day and it gets hungry. Skip a week and it dies — for real, no second chances. A virtual pet that lives or dies by whether you actually move today.
How Pyxie works
Three steps. No spreadsheets.
-
01
Hatch your egg.
The game rolls one of eight elemental lines for you — Ember, Tide, Verdant, Gale, Stone, Umbra, Aurora, or Static. You don't pick. Whatever hatches is yours for that pet's life.
-
02
Train.
Log a workout, your pet eats. Easy walk or hard session — both count, but they grow different creatures. Your reps decide the evolution path, even though your line was decided for you.
-
03
Don't stop.
Miss a day, stats decay. Miss two, your pet starves. Miss enough, it's gone, and you start over with a new egg.
The hook
There are no second chances.
Most fitness apps give you streaks you can lose, badges you can re-earn, and "let's get back on track!" emails when you slip.
Pyxie doesn't.
If your pet dies, it's gone. You release the body, hatch a new egg, and start at stage zero with no record of the pet that was. The streak you built is buried with it.
That sounds harsh. It is. It's also the part that finally makes you go to the gym.
The roster
Sixteen finals per line. Your habits pick which.
Every time your pet hits an XP threshold, Pyxie looks at the workouts you've actually done and forks the path. Easy walks grow one creature. Burpee sprees grow a different one. You don't choose — your training does.
248 named forms across eight elemental lines. You only get one line per egg, rolled at hatch. Most players will only ever meet a handful of forms in a lifetime of pets.
What it isn't
A few things Pyxie won't do.
- No macros, no meal plans, no "fitness journey." If you wanted a coach, you'd already have one.
- No "you got this!" notifications. Your pet sends its own. They're harder to ignore.
- No buying your way back to a dead pet. The dead stay dead. That's the whole deal.
- No ads, no sponsored evolutions, no NFTs. Just one egg, your reps, and what happens next.

Why this exists
A reason to move that isn't a number.
The hardest part of working out isn't the workout. It's getting up to do it.
I built Pyxie for me and my kids. I needed a reason to move that wasn't a number on a scale or a streak in a habit app — something that would actually be sad if I let it down. Something small enough that my children could love it too. A reward to show for the effort, that we could watch grow alongside us.
The evolution mechanic is a love letter to Eevee — the Pokémon with eight different futures depending on how you raised it. The idea that a single starting point could branch into wildly different creatures based on your choices is the design idea Pyxie is built on. Eight elemental lines instead of one, hidden alt-branches at every stage, 248 named forms across the whole roster — but the spirit is Eevee's.
Pyxie isn't a product looking for a market. It's a thing I needed, that I'm sharing in case you need it too.
