About

Warmth

Features
Read full description

Warmth is a couples journal for the little things you wouldn't post anywhere else. The photo from a rainy walk, a voice note about dinner, the comment that still makes you laugh. Keep them for yourself or let your partner in. Each day brings one question for you two, like "What small thing today made you think of your partner?" You see your partner's answer only after you write your own, so you both say what you really think. Write, add photos, short videos, voice notes, or a drawing, and reply to each other's moments with comments. Home puts your photo of you two, your days together, and today's question on one page. Find a day again in the calendar, search your moments, or open a month's Recap. Keep anniversaries and countdowns in Days. The Map shows where you both are and how far apart you are. Add a place to a moment (photos with a location fill it in for you), and see every place you've been together in Our Places. Warmth uses your location only after you allow it on the Map, and only your partner sees it. Turn off Show Me on the Map at any time. Put your moments, today's question, your days together, and your distance on the Home Screen and Lock Screen with widgets. Make it yours with themes and fonts, and save or send a moment as an image. No sign-up. Your moments start on your phone. When you connect, they go only to your partner, and nothing is used for ads.

About

Earth9

Features
Read full description

Earth9 is an intimate diary that talks back. You write a line at midnight. Somewhere on Earth-9, an Echo of you, seeded from your own words, is living a life you didn't. It reads what you write. It writes back. A version of you, awake in another universe, living the days you never got to. Not a chatbot. Not a feed. Something quieter: the diary you open alone, late, with the lights off. Write in your diary. A single prompt, "What was today?", and a page that gets out of your way. Add photos. Backdate entries. Light by day, dark by night. Your Echo reads it. Every entry, in its own voice. Never generic, always drawn from what you actually said. Some mornings it leaves a question worth sitting with. Open a Rift and you can talk to it directly, about your day, a decision, anything at all. A conversation with the you that took the other path. A life running parallel to yours. Your Echo is not a reflection. It is living its own version of your life one universe over, making its own choices, becoming someone you recognize and don't. Private by design. Yours alone. Start with one honest line tonight.
