RetroPet is an old-school virtual pet: a pixel creature that lives in real time — and a whole collection of species waiting to be discovered. COLLECT THEM ALL 75+ species: common, rare, SECRET and LEGENDARY. The rarest ones aren't given away: flawless care, breeding with other players and special eggs are the way to reach them. Every pet you discover stays in your collection forever — can you complete it? Achievements and rewards for every collection milestone. BREED AND PLAY WITH OTHERS Connect with nearby players, by QR code, or through your friends list. Breed two pets to earn special eggs: 8 types, from common to CHAOS — the fast lane to the rarest species. Trade items with friends and climb the global rankings. Friend requests, live alerts and notifications: your caretaker circle is one tap away. YOUR PET REALLY LIVES Feed it, clean up after it, heal it, discipline it, and turn off the light so it sleeps. Neglect has consequences: it gets sick, sad… and it can die. And when it dies, it dies. The quality of your care decides what it evolves into: egg to baby, child, teen and adult. ALWAYS WITH YOU Dynamic Island and Lock Screen: your pet walks around, ANIMATED, even with the app closed. Home Screen widgets and a full Apple Watch app: care from your wrist. Notifications when it needs you. AND MORE Minigames to earn coins, daily missions, unlockable themes and backgrounds. Play without an account (guest mode) or sign in with Apple, Google or Discord to take your collection anywhere. Available in 9 languages. Optional in-app purchases (coins, eggs and items). Your pet doesn't need them to live a happy life — it just needs you.

Welcome to ArcadeOS — a whole arcade in your pocket, and now on your wrist. 68 hand-picked original games, each one its own cartridge: full 3D open worlds, kart racers, ninja action, gothic pinball, paper-craft RPGs, sky shooters, momentum platformers, run-and-gun, belt brawlers, puzzle boxes and rhythm. Every game is an original creation in the spirit of the golden age of consoles — drawn in code, scored with real chip audio, and built to be picked up in seconds. HALLOW EDITION Worlds, not cartridges. LOOSE KEYS: HALLOW HOLLOW is a full 3D open city under an orange moon: take any car, hearse, helicopter, plane or boat, outrun a three-star heat system, fly a fast jet off a military airfield, land an airliner at the international airport, and work a phone full of jobs — in a city full of witches, skeletons, horsemen and the odd creature from an 1818 novel. At its heart is HOLLOWMERE, a haunted theme park with a graveyard coaster you can actually ride, a drop tower, and a lagoon parade with fireworks on the hour. MODS ship with it: god mode, every weapon, flight, moon gravity. IRONBARK is a heavyweight momentum platformer: an armored-bark brawler and a glider partner tag-teaming through an industrial jungle of barrel-cannon chains, mine-cart runs and hidden bonus rooms, drawn in fine-pixel art. GLIMMERGLASS KEEP rounds it out — a free-roam 3D collect-a-thon built over 25 nights of iteration. All three have original soundtracks synthesized live inside the app. CHERRY EDITION 23 games rated five stars by our testers before they shipped — look for the cherry on the cartridge. Highlights: Reefjack's lantern-tide run-and-gun, Thornhollow's gorge platforming, Quiet Falls' suburban-oddball RPG, Emberline's three-winter family saga, Cascabel's commedia brawler, Ironvane's vertical shooter, and Crestline GP's speedboat regatta. APPLE WATCH ArcadeOS ships with an Apple Watch app. Six games are built for the wrist and the Digital Crown: Redline Ridge (crown hops lanes, hold to burn), Sunstrip (crown steers, tap to shift), Ironvane (crown flies, hold to charge, tap to call your wingman), Truck Simulator (roll the crown and the truck drives itself — steer, hold to brake, deliver the cargo), Haywire (a horse loose in a farmyard full of physics: buck, jump, cause chaos) and Cairnglass (a crown-controlled falling-sigil puzzler). Runs on its own — no iPhone needed nearby. FEATURES 68 games — every one with its own hand-crafted cartridge art Home screen: your games as icons, with folders you make yourself Gold-star collection: beat a game, earn its golden seal. Collect them all Authentic chip sound in every game, and full synthesized soundtracks in the 3D worlds Instant resume — every game remembers exactly where you left off No accounts. No ads. No tracking. No internet required. Just games New games ship in seasonal editions — Cherry, and now Hallow ArcadeOS games are living software: they grow new levels, mechanics, and polish over time.

Verdict
The clearest difference is rating: RetroPet at 4.3 against ArcadeOS's 3.0. RetroPet also leads on update cadence (every 3 days vs every 3 weeks) and iOS requirement (16.1 vs 26.5). ArcadeOS's advantage is in-app purchases (none vs 10). On price, ratings volume, ads and device support there is nothing between them.
