When your head is full, it can be hard to know what belongs in front of you and what can wait. KUU is a quiet voice-first app for brain dumps, overthinking, scattered ideas, and the small worries you do not want to keep carrying. You can speak what is on your mind. It does not need to be organized. KUU turns what you said into text and gently separates it four ways: Now / Later / Park / Let go. The point is not to do more. It is to make a little room in your head. ■ When to use it - Before bed, when your mind starts running. - When the same thought keeps looping. - When task managers have started to feel heavy. - When you want to be heard, but do not want to send it to anyone. - When talking out loud helps you understand what you mean. - When an idea appears before it has a shape. - When you do not want to forget something, but it is not ready to act on. - When voice feels easier than typing. - When your hands are busy: driving, cooking, getting ready, or moving through the day. ■ The 4 ways Now — Something that may feel lighter if you look at it soon. Later — Something to return to at another time. Park — An idea, feeling, or question that does not need an answer yet. Let go — A worry or thought you may not need to keep holding. These are not priorities or scores. They are quiet ways to hold what you said. ■ How KUU is different - Unlike a notes app, KUU starts with speaking, not writing. - Unlike a task manager, KUU does not turn every thought into something to do. - Unlike an AI chat, KUU does not give long advice or add more things to think about. KUU receives what you said and separates it into smaller, easier pieces. ■ What you can do - Speak naturally, even when your thoughts are all mixed up. - See your words as text. - See only what needs your attention now. - Keep later thoughts, parked ideas, and things to let go in their own places. - Revisit what you have said when you want to. ■ Voice and data - Raw audio is not kept. - What you said is saved as text so you can look back later. - Sorting uses AI. Only your words as text are sent, and nothing is kept. - Your saved text syncs only to your private iCloud. - Other people, and the app developer, cannot read it. ■ On your Mac KUU waits quietly in the menu bar. You can speak without opening a window, and it carries all the way through to Now / Later / Park / Let go. What you said before is always a glance away. KUU is not here to add more thoughts. It is here for the space between: “I do not need to solve this right away” and “I do not want to keep holding it in my head.” — Speaking makes room in your mind.

Everything that is yours, in one place. Krivo is a shared space for two: plans, the things that matter, and more of what you enjoy doing together. Plans, tasks, lists, wishes, memories, documents and important dates — without digging through chats, notes and screenshots. DRAWING TOGETHER One canvas for the two of you, shaped like a home screen. You draw with your finger and the line turns up on their phone as it happens. Save the picture and set it as the wallpaper: the drawing ends up where you both look every day. Leave it on their screen and it shows up on the widget, without opening the app. SHARED CALENDAR Events, trips, birthdays and anniversaries in one calendar you both see, with reminders and repeating events. TASKS AND LISTS Split what needs doing and tick it off together: groceries, films to watch, what to pack. What one of you adds shows up on the other's phone. QUESTION OF THE DAY One question a day for the two of you. You answer first, and only then see what your partner wrote. A hundred questions and a streak that grows while you keep it. DO TOGETHER One plan a week to break the routine: a walk after dinner, a new recipe, an evening without screens. Not for you? Ask for another, or write your own. DECIDE TOGETHER What's for dinner? What are we watching? Each of you votes without seeing the other's vote, and the result opens once you both answered. WISHES AND GIFT RADAR Keep what you want, with a price and a link if needed. The radar warns you when a date that calls for a gift is coming. GOOD TO KNOW Sizes, favourite food, what they can't stand. The things you forget exactly when you need them. NOTES AND TIME CAPSULES Shared notes for what doesn't fit in a task, and capsules that open on the date you choose. VAULT Documents and details that must not get lost: passports, policies, contracts. They are encrypted end to end on the phone — we cannot read them either. CYCLE A menstrual cycle log that belongs to the person keeping it. It is stored encrypted, and your partner sees only the summary she chooses to share, or nothing at all. SAVINGS, CARDS AND OUR YEAR Savings goals with what you have put aside, loyalty cards at hand, and a look back at the year you spent together. WIDGETS The days you have been together and the note they left you, right on the home screen. No need to open the app. A SPACE FOR TWO Connect your accounts and share only what you want to share. Every section can be switched off. PREMIUM Premium can be bought monthly, for 6 months or yearly, or as a one-off payment for good. The price is shown in the app before you buy. One subscription turns Premium on for both of you. The subscription renews automatically unless you cancel at least 24 hours before the period ends. You can manage and cancel it in your Apple account settings. The app is in Spanish, English, Portuguese and Russian. For ages 18 and up.
