## What is Futari Umi?

Futari Umi is a gentle aquarium app where you and your partner or someone special can care for one little sea together.

Feed your fish, collect shells, and welcome new companions. Small moments of daily care bring your shared aquarium to life. Answer the same question each day to discover new sides of each other and make space for meaningful conversations.

Your answers are saved in the calendar, alongside memories of your fish growing and new arrivals. Send a message in a bottle to share the words that can be hard to say out loud. Whether you live far apart or simply have busy days, your little sea gives you a place to reconnect.

Enjoy a calmer everyday life with your fish. You can start on your own, then connect with your partner whenever you are ready. Grow a little sea, and a little closer, at your own pace.
