SinalFlag helps you understand the health of your relationship — with more clarity, privately. Assess nine dimensions (communication, trust, respect, reciprocity, emotional safety, conflict, boundaries, autonomy, and connection). Talk with a specialist, unpack an episode, journal what happened, and track trends and patterns over time. The app does not tell you whether to stay or leave. It is not therapy, not a diagnosis, and not a “toxic relationship” detector. Safety alerts stay separate from your average score. Your records stay in your account. We use what’s needed for the app to work, including chat and situation analysis. We don’t sell your texts. Optional subscription, with a 7-day free trial. Billing through Apple.

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.
