A virtual pet that lives on your phone screen. Adopt a tiny buddy, name it, feed it, clean it, play with it, and watch it grow from baby to teen to adult while it answers every tap, swipe and shake with a face of its own. Screen Pet is a real care simulator, not a static cartoon. Four needs — mood, energy, hunger and cleanliness — drift with the hours you are away, so your buddy genuinely notices when you show up. Fifteen care, play, item and emotion actions each move those bars differently, run on their own cooldowns, and shape the 12 expressions your pet pulls back at you. Everything runs offline on your device: no account, no ads, no internet required. WHAT YOU GET - A buddy that answers back — tap, swipe or shake and get an instant animated reaction with sound and haptics - Needs you can actually read — mood, energy, hunger and cleanliness bars that drain over time and recover from the right action - Real growth to work toward — Baby to Teen to Adult evolution driven by the days you keep showing up - 15 distinct actions — feed, bathe, brush, heal, massage, fetch, hide and seek, teach tricks, hug, dance, sing and more - A pet that looks like yours — 8 colors, 6 accessories, 6 sky themes and 4 room scenes to settle into - A reason to come back tomorrow — three fresh daily missions, a reward-chest track, streaks, coins, care levels, six achievements and two 30-second mini-games PERFECT FOR - Anyone who wants a pet but cannot keep one at home - Fans of 90s pocket-pet toys and cosy care simulators - Fidgety hands that want a calm 30-second break, not another shooter - Anyone who likes a small daily ritual with a streak worth protecting WHY NOT JUST TAP A FREE IDLE CLICKER? Because a clicker wants your thumbs, not your attention. Screen Pet has no ad breaks between taps, no timers begging for gems and no leaderboard grind. Your buddy's needs move slowly and honestly, the mini-games are short on purpose, and one visit a day is enough to keep it thriving. PRIVACY No account, no sign-up, no ads, no tracking, no analytics. Your pet, its stats, streak and every setting stay in your device's local storage and are never uploaded anywhere. FULL ACCESS Full access unlocks all 15 care, play, item and emotion actions, all 8 pet colors, all 6 accessories, and all 10 backgrounds and room scenes. Choose a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings. Adopt your buddy tonight, give it a name, and feed it its first snack.

About

Qubitchi

Features
Read full description

Qubitchi is a virtual pet that's actually alive — because it's a real qubit on an IBM quantum computer. Most pets are made up. Qubitchi isn't. Adopt one and you're adopting a genuine quantum bit on real superconducting hardware, chilled to fifteen millikelvin — a hair above absolute zero. Its mood is its physics: when the qubit holds a clean quantum state, your pet is thriving. When noise creeps in and the qubit starts to forget — decoherence, the central problem of quantum computing — your pet grows drowsy, unwell, and eventually decoherent. Nothing is faked. Qubitchi is a window onto a real machine. HOW IT WORKS • Every reading comes from live IBM Quantum telemetry — coherence times (T1/T2), calibration, and queue depth. • Health is judged against each qubit's own 30-day baseline, never an absolute scale. Every qubit is different, so a "good" chip at its own normal is just as healthy as a "great" one at its. • Tap your egg to hatch it, then watch your pet grow from hatchling to adult over days. WHAT YOU CAN DO • Adopt any qubit on any available backend — each is its own pet, with its own age. • Follow a 7-day coherence chart, like a paediatric growth chart for a quantum bit. • Explore the neighbourhood — the other qubits sharing your pet's chip in IBM's heavy-hex layout. • Read the diary — a running log of how your pet's mood has shifted. • Earn badges for real milestones: holding a state past 100 microseconds, surviving full decoherence, bouncing back from a rough spell. • Climb the Quantum League — live leaderboards ranking every qubit on the fleet by coherence, health, and stability. • Browse your menagerie — every qubit you've ever adopted, in one place. LEARN BY CARING Decoherence is the hardest idea in quantum computing to feel in your gut. Qubitchi makes it personal: you come to understand what T2 means because your pet's life depends on it. No equations required — just attention. PRIVATE BY DESIGN Qubitchi collects nothing about you. It fetches public hardware data and keeps your adopted pets on your device. No accounts, no tracking, no ads. Qubitchi is an independent project and is not affiliated with, or endorsed by, IBM.
