Your time is not running out somewhere far away. It is running out today. Sharkspan counts down the years you have left, then takes out the hours your day already costs - sleep, the commute, the feed. What remains is clean time: the part that is actually yours to spend. YOU SET THE NUMBER No quiz, no AI, no health data, no prediction. You enter your age and the age you expect to reach, and you change either one whenever you want. TODAY IS THE UNIT A lifetime is a statistic. The hours left before midnight are a decision. Sharkspan shows both, and only today's number ticks - because today is the only one you can still spend. WHAT YOU GET • Clean time - your remaining years, minus everything you spend every day • Spendings you own - your own list, to the minute, edited any time • Today - the hours, minutes and seconds left before midnight, live • Home Screen widget - the clean days left in this year, at a glance • A line a day - a real sentence by a real author, never a lecture • Twelve languages, plurals and all NOTHING LEAVES YOUR PHONE No account. No sign-up. No tracking. No analytics. No network. Your age and your list stay on the device, and the privacy manifest says exactly that. FREE The app and the widget cost nothing. No subscription, no unlock, no ads. A shark that stops swimming dies. Move - you are on a clock.
