Don't spend. Mint gold. SpendZero turns every no-spend day into a gold coin: watch them pile up in your Coin Vault, fill your year on the Mint Calendar and see what a year of not spending could be worth. Streaks, XP, quests, badges and a living wealth tree make it a game you actually want to win. Doing a no-buy month, a low-buy year or No-Spend January, or just trying to stop impulse buying? SpendZero makes every day you don't spend feel like a win. NEW IN 2.0 • Coin Vault: each sealed day drops a gold coin into a glass jar you can tilt and shake • Mint Calendar: your whole year in gold coins, brighter on the days you kept more • Savings forecast, all-new charts, and what your savings could buy • Monthly Recap: a story of your month, ready to share • Seal today from your Lock Screen, Dynamic Island, Control Center or Siri • A living wealth tree: day and night, the seasons, lights in December • Unlock Gold, Emerald and Midnight app icons as you level up A GAME YOU WIN BY NOT SPENDING Mark a no-spend day and it's sealed with a gold coin. Your streak ticks up, rewards pop in, and you see how close your next milestone is. • Streaks, with streak freezes that cover you on a rough day • Daily and weekly quests that progress from what you actually do • 25 levels, from Frugal Novice to Wealth King • Badges for 7-, 30-, 100- and 365-day streaks and savings milestones • Challenges like the 30-Day No-Spend Challenge, Coffee Detox Week and seasonal ones like No-Spend January, or make your own GROW YOUR WEALTH TREE Your tree is one of a kind. It grows with every level, hangs gold coins as your savings add up and follows your real day, from sunrise to moonlit nights. Let your streak lapse and it starts to wilt; one no-spend day brings it back. CRUSH IMPULSE BUYS Something sitting in your cart? Log it. Walk away and the money counts as saved, with XP to prove it. Caved? No shame: log it and keep going. Essentials like groceries and transportation don't break your no-spend day.
