Chijian: A Quiet Koi Pond

Make room for a quiet pond. Tap the water, invite fish closer, and watch them grow. Collect favorite colors, choose a gentle soundtrack, and return whenever you like.

A little pond. A moment to yourself.

Chijian is a gentle fish-keeping app. Watch fish glide through the water, make a few ripples, and take a small pause in your day.

TOUCH THE WATER Tap to make ripples, or hold a finger on the water to attract nearby fish. Each fish has a personality and may occasionally share a short line of dialogue.

WATCH YOUR FISH GROW Drop food into the pond. Fish that eat can grow, and fully grown fish can stay in your collection or be sold for in-app coins. Your fish do not die, become ill, or lose progress because you have been away.

COLLECT YOUR FAVORITES Choose from koi, goldfish, bettas, guppies, and angelfish, with 18 appearances across five species. Check growth in Storage and arrange the priority of your limited food supplies. Basic food is always available.

ENJOY THE ATMOSPHERE Seasonal scenery changes over time within the app. Choose from four background music tracks, or turn the music off and simply watch the pond.

COME BACK WHEN YOU LIKE No Chijian account is required. Core fish-keeping works offline, with progress stored on your device. Available on iPhone and iPad, with Simplified Chinese and English language options.

You can store up to five feeding opportunities, recovering one every 30 minutes. Watching your pond and touching the water do not use them.

The app and its core features are free. The launch version has no real-money purchases or subscriptions. In-app coins are for gameplay and cannot be exchanged for money.

Progress is currently stored locally, without account-based cloud sync. Uninstalling the app or changing devices may result in lost progress.
