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 clean hours, minutes and seconds left in this day, 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.

Encrypted notes that only you can read. hYYa Encrypted Notes is a private notepad, diary and journal for iPhone, iPad and Mac. Every note is encrypted on your device before it is saved. There is no hYYa account to create and no hYYa server to hold a copy, so your notes stay yours alone. Your notes. Your iCloud. Your Google Drive. FOR YOUR EYES ONLY • Encrypted on your device, so only you can read your notes. • Titles and folder names stay private too, not just what you write. • Opens with Face ID or Touch ID. • Find anything in seconds, and your notes stay private while you search. SYNC ON ALL YOUR DEVICES • Through your own iCloud Drive, across your iPhone, iPad and Mac. • Through your own Google Drive too, to reach your other devices. Only you can read what's there. • Or keep your notes on this device only. Writing, search and export all work offline. • Edits from two devices are merged back together, and if a note changes in two places at once, both versions are kept. Nothing you typed is ever silently discarded. WRITE THE WAY YOU THINK • Headings, bold, lists and checklists appear as you type. • Folders, pinned notes and colour labels. • Write in any language: Arabic paragraphs read right-to-left and English ones left-to-right, in the same note. • Attach pictures and files. Pictures show inside the note; PDFs and other files open with a tap on iPhone and iPad, or in your usual app on Mac. Every attachment is encrypted exactly like the words around it. YOUR WRITING STAYS PORTABLE • Export every note as plain Markdown, with its pictures and files beside it, whenever you like, for free. • Import from Markdown, plain text, HTML, RTF or an Evernote export. • No ads. No tracking. Nothing watching what you write. MADE FOR IPHONE, IPAD AND MAC • Built for each device, so it feels right at home. • On Mac: a full menu bar, keyboard shortcuts, printing and a proper Settings window. • On iPad: your folders in a sidebar, and drag and drop to file a note. • Dynamic Type, VoiceOver, Reduce Motion, and light and dark themes. FREE, AND HONEST ABOUT IT Keep up to 2 notes free for as long as you like, with sync and every other feature, no time limit and no trial to run out. Encryption, biometric lock, import and export are free for everyone and always will be. One purchase unlocks unlimited notes on iPhone, iPad and Mac together. It is never a subscription, and nothing you have written is ever locked, hidden or taken away.
