You started by pasting an answer off Stack Overflow. Twelve tiers later you are running an autonomous agent fleet, a server farm and a quantum compiler, and the changelog has started calling the next one The Singularity. Dev Idle is an idle game about being an iOS developer, made by one. Tap to write code, hire the pipeline that writes it for you, then ship a version and do the whole thing again, faster. THE LOOP • BUILD — Twelve generator tiers. Every 10, 25, 50 and 100 you own doubles that tier's output, and there is no last milestone. The tap button starts out as "Write code". It does not stay there. • SHIP — Submit to App Review and bank Reputation, an income multiplier kept until you go public. Your first review takes three minutes, so you ship in your first session; after that it is thirty minutes, like the rest of us. Yes, that is the joke. • LAB — Ships pay Commits for permanent upgrades; milestones mint Pull Requests for a 16-node skill tree. A bad run still pays. • SHOP — Conference Tickets buy time, never gameplay: expedite a review, double an offline haul, or collect eight hours at once. • PASS — Four-week Sprint Pass seasons named Legacy Code, Merge Conflict, Code Freeze… Fifty tiers earned by playing: a badge at 25, a finished mark at 50, the season's accent color at premium tier 50, and a recap of what was collected for you when it ends. • RÉSUMÉ — Twelve career tracks and 59 lines, graded as you play. Most pay Conference Tickets. • IPO — Go public: trade your whole Reputation for Shares and raise the level cap on every Commit upgrade. There is a celebration. Then the horizon moves again. SOMETHING IS ALWAYS ON FIRE • Every so often, prod goes down. Tap the incident to hotfix it for a burst of income. • A daily streak you can see, a Retro voucher worth an hour of production every seventh day, and a welcome-back bonus after three days away. • #general marks your milestones, locked tiers tease what is next, and App Review keeps you posted. AN ORIGINAL SOUNDTRACK Seven loops follow your company as it grows, from lo-fi and jazzy chillhop to synthwave and ambient, and your career unlocks them; one is an 8-bit bonus. Sound effects for every key moment, a jukebox, and separate switches for music, effects and haptics. Silent mode silences the game; your own music keeps playing. THINGS WE CARED ABOUT • No ads. Not between screens, not for a bonus, not ever — there is no ad code at all. • Plays offline, with a proper "while you were away" report. No account, no advertising identifier, no tracking. Your save syncs through your own iCloud. • A Live Activity counts your review down on the Lock Screen and in the Dynamic Island, and says when it is done. • Dark editor themes, because it is that kind of game, and a swag store where Commits and Pull Requests buy original color themes and tap-particle styles. • Release notes you can share as an image. • Twelve languages. • Balanced by simulation, not by vibes. Tier 4 inside two minutes; The Singularity considerably later. FREE TO PLAY, AND MEANT IT Optional purchases shorten the road. Not one of them unlocks gameplay you cannot reach by playing, because a wall you cannot climb is a game you stop opening. Dev Idle Pro — $4.99 a month in the US, with a 7-day free trial for new subscribers: ×2 income, full-rate offline earnings, a bigger daily Ticket bonus, an exclusive editor theme, and every season's premium Sprint Pass track.
