Pixfin for iPhone, iPad and Apple Watch

Meet the fish that grows up when you take care of yourself.

Pixfin is a cozy cartoon aquarium built around one simple idea: walk, and your creature explores its world; drink water, and it grows from a tiny hatchling into a fully-grown fish. No streaks to lose. No guilt. No "your pet died" - just a little companion that thrives when you do.

Free to download. iPhone and iPad, with an Apple Watch app included. Requires iOS 26 or later.

  • No streaks to lose
  • Nothing ever dies
  • No ads, no tracking
  • Widget, Watch and iCloud free forever
  • 32 real species

Every tank stars one creature you name and raise. Log a glass of water and it advances through real biological growth stages. Take a walk and it swims somewhere new, the whole scene shifting around it. When both are complete, your creature matures - and fills its slot in a gallery of all 32 species, where the fish, octopus, jellyfish, seahorse and more you haven't raised yet are already waiting.

Grow a creature, not a number

  • Walk and drink water to grow a real aquatic creature through its natural life stages
  • Name every creature and watch it develop - coloration, fins, detail
  • Every species grows on its own real timeline - three stages for an octopus, seven for a moray eel

Collect all 32 species

  • Every species has a slot from day one, across five habitats - you always know what's left to raise
  • Raise the same species more than once and each creature keeps its own name, journey and history
  • Scrub back through any creature's growth stages, and see which days you walked and drank the most

Free forever - no catch

  • Home-screen widget, so your tank lives on your Home Screen
  • Apple Watch app + complications to log and glance from your wrist
  • iCloud sync across all your devices
  • No ads. No tracking. Ever.

Learn as you go

Questions about Pixfin

Is there a habit tracker without streaks?

Yes. Pixfin is built without them - no streak counter, no chain to keep alive, nothing that resets. What replaces it is a creature you are raising: every walk and every glass of water you log moves it toward its next growth stage, and progress you have already made is never taken back.

Which habit apps don't punish you for missing a day?

Pixfin is one, by design. Miss a day, a week or a month and nothing is lost: no counter resets, nothing dies, and your creature is exactly where you left it. Notifications are milestone-only, so the app never nags you or tells you that you have broken something.

What is a gentle habit tracker?

Usually it means an app that records what you did without scoring you on what you did not. Pixfin works that way: no streak, no daily target you can fail, and no pet that suffers when you are busy. The only thing that ever changes is how far your creature has grown.

Is there a habit tracker without streaks for ADHD?

People often go looking for one because a broken streak turns a missed day into a reason to quit. Pixfin has no streak to break: progress only ever accumulates, and nothing is taken away. It is not a medical or therapeutic tool and makes no claims about ADHD or any other condition - it is simply built so that missing days cost you nothing.

Does Pixfin use streaks?

No. Pixfin has no streak to lose and nothing that can break. Miss a day and nothing bad happens: your progress is always kept.

Can my creature die if I stop playing?

No. Nothing ever dies in Pixfin. There is no “your pet died”, just a little companion that thrives when you do and waits when you cannot.

What makes a creature grow?

Two things: walking and logging water. Pixfin reads your step count from Apple Health, and you tap Log water each time you drink. Pixfin counts the act of logging, not the amount, and each milestone grows your creature to its next life stage.

Is the home-screen widget free?

Yes. The home-screen widget, the Apple Watch app and complications, and iCloud sync across your devices are all free forever, with no subscription.

Is there an Apple Watch app?

Yes, and it is free. The Apple Watch app and complications let you log water and glance at your tank from your wrist. Your iPhone is the source of truth and the watch mirrors it.

Does Pixfin sync between my iPhone and iPad?

Yes. iCloud sync across all your devices is included at no cost. Your progress is permanent and syncs privately through your own account, so reinstalling Pixfin or setting up a new device restores your tank, water history and creature gallery.

Does Pixfin show ads or track me?

No ads. No tracking. Ever. Pixfin has no accounts, and health data stays on your device and in your own iCloud. It is never sent to us.

How many species can you collect in Pixfin?

32, across five habitats. Every species has a slot from day one, so you always know what is left to raise: fish, octopus, jellyfish, seahorse, moray eel, giant squid, koi, firefly, piranha, electric eel, pink river dolphin and more.

Is Pixfin free?

Yes. Pixfin is free to download and free to keep using. Pixfin Premium is optional, as a subscription or a one-time Lifetime purchase.

Pixfin reads your step count from Apple Health, with Steps turned on under Profile > Apps > Pixfin. You can review or turn off Health access at any time in the Health app.

Is Pixfin available on Android?
