DopamineOS

DopamineOS is a tiny fake phone, living inside your real one. Open it and you get a whole home screen of glossy, useless apps — a feed that never ends, a stock market for coins that aren't real, a food app that never actually delivers, even a music player full of songs that don't exist. Every tap pays out in Sparks, a pretend currency you can hoard, spend on cosmetics, and absolutely never cash out. It's all the satisfying little dopamine loops of modern apps — the pulls, the wins, the streaks — with the manipulation surgically removed. ALL THE DOPAMINE • LikeLoop — post nothing, get adored anyway • DoomScroll — an infinite feed of harmless nonsense • HypeTrader — get rich in a market that isn't real • CraveCart — order food that never comes (you keep the calories and the cash) • Dopify — a music app playing endless lo-fi loops by artists who don't exist • …and a dozen more: SnackGame, SwipeHeart, MoodWeather, StreakForge, and friends NONE OF THE DAMAGE • No ads. No accounts. No logins. No tracking. • Nothing is ever uploaded — everything lives on your device. • And the headline feature: no real notifications, ever. The fake notifications are pure in-app theatre. The moment you put the phone down, it goes completely silent. MAKE IT YOURS • Earn Sparks everywhere and spend them on wallpapers, icon packs, frames, and sound packs in the Vault. • Keep only the dopamine you want — remove any mini-app from your home and add it back anytime from Settings. • Two looks: a calm, low-stimulation "Quiet Premium" theme (default) and a vivid neon mode. ONE HONEST TRANSACTION There's a single optional one-time "Pro" unlock for cosmetics, the full app lineup, and a Spark bonus — no subscriptions, no per-app upsells, no luck-based nonsense. The whole joke would fall apart otherwise. Put down the apps that take. Pick up the one that just gives.

Verdict
The clearest difference is in-app purchases: ReplyRoom AI at none against DopamineOS's 1. ReplyRoom AI also leads on update cadence (every 9 days vs every 2 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
