Nudii — a private, on-device AI virtual pet: raise a little sea creature you actually talk to (iOS)

Hey Solo dev here, sharing my first public beta.

**What it is:** Nudii is a virtual pet — a little sea creature (a nudibranch) you hatch, care for, and grow Tamagotchi-style. The twist: it has a real personality you can chat with, and it remembers you over time. The AI brain runs 100% on-device (Powered by Gemma4), so it works offline and nothing leaves your phone — no account, no servers, no tracking.

**Features:**

- Hatch and raise your creature through life stages — feed, clean, play, sleep.

- Chat with it: on-device AI, persistent memory, its own personality.

- Decorate your own reef and collect different sea species.

- Rewards you for moving (HealthKit steps/workouts).

- Fully private: on-device model, no sign-up, no data collection.

**What I'd love you to test:**

- Onboarding / hatch flow — is it smooth?

- The chat — quality, latency, and whether the memory feels real.

- Performance — battery and thermals on longer chats (it's a real LLM running locally).

- Anything that crashes or feels off.

**Requirements:** iPhone with A17 Pro or newer (8 GB RAM floor for the model), iOS 26+. Free to download; a few optional in-app purchases exist but are free to try in the TestFlight sandbox.

I'm the developer and I'm watching feedback closely — shake to send it in TestFlight, or just drop it here. Thanks for trying it! 🐙

I grew up on Tamagotchis, so I built one you can actually talk to — a tiny sea creature that hatches, evolves, and remembers you 🐚

It's in free beta right now (TestFlight). Needs a fairly recent iPhone (A17 Pro or newer, iOS 26+).

I fine-tuned Gemma 4 (E2B, Q4_K_M) and got it running 100% on-device in an iOS app — a little sea-creature companion you actually talk to. Offline, no servers, beta's open.

Requirements: iPhone with A17 Pro or newer (8 GB RAM floor for the model), iOS 26+. TestFlight beta is open to anyone with a compatible device.
