You're busy because the cup was already full. ZoneOut is not a productivity app — it's the opposite. It helps you practice doing nothing. Here, you "go public" and get your own ticker code. Each day you stop and rest for a while, it's logged as a candlestick. The more regular you are, the steadier your "price." This is not real investing — no real money, no trading. The stock market is just a metaphor that makes resting visible, like tending a little stock that's yours. Five ways to rest — pick the one that fits right now: · Zone Out — do nothing, let your thoughts settle · Relax — let the tension go · Let Go — write down what weighs on you, then release it · Meditate & Flow — unlock as you go, at your own pace · Candles & Score: see the rhythm of your daily rest · Market value: turn your rest hours into a purely referential "market value," and toggle between index and value · A milestone ladder: morning outlook cards, Meditate, Flow… unlocked step by step · You can graduate: when you've learned, you can delist — leaving isn't losing Our promises: · We won't tether you or guilt you back with notifications · We won't punish a healthy exit · We won't push overuse · We won't lock features behind a paywall Free, supported by ads. Nothing is something.
