Clione Aquarium: Relaxing Tank

Sea Angel Sleep Sounds & Calm

Free · In‑App Purchases

A sea angel drifts through a tiny tank in your hand. Soft music and a sleep timer at bedtime, a gentle clock on your desk. Unlock 11 tiny dioramas. No pop-up ads. Watch the sea angel, the little angel of the drift ice, in a calming aquarium. A clear, glassy body with a soft glow of red inside. Flapping its tiny wings, the clione drifts slowly through the water. Before bed, or between work and study, take a moment to do nothing and simply watch. ■ Each one is a little different Every clione has its own wingbeat and its own habit of tilting to glide sideways. Touch the tank and ripples spread across the water surface, and any clione nearby gently drift away. ■ Look around, look closer Swipe to orbit the view and pinch to move in. ■ Make it yours ・Tank shape: rounded, cube, cylinder, hexagonal prism, capsule, sphere, full screen ・Background: Pearl, Lapis, Sky, Pale Indigo, Wisteria, New Leaf, Evening Calm, Champagne, Silver, Rainbow, Drift Ice, Night ・Floating items: drift ice, diamond dust, snow, specks of light ・Number of clione: 1 to 7 (4 or more with Premium) ・Light effects: rippling light, light rays, glow, glass refraction ■ Water sounds and music Listen to the quiet sound of water and, now and then, pieces of drift ice gently touching. You can also choose from 10 calm music tracks (6 free, 4 with Premium), or play along with music from other apps. ■ Sleep timer Choose 15, 30, 60 or 90 minutes. When time is up, the sound fades out over 30 seconds and the screen slowly dims. The sound keeps playing until the timer ends, even with the screen off. ■ A bedside clock Show the clock and leave it on your desk or nightstand. You can keep the screen on while charging, and lock it so touches do nothing. ■ Easy on battery and device The app draws less while you are just watching, and lowers its load automatically when the device is warm or in Low Power Mode. Choose Saver, Standard or High quality. ■ Little dioramas on the tank floor Place one of 11 little dioramas on the bottom of the tank, like an ice castle, a sunken temple, a resting whale or a lighthouse cape. Snow Village and Frost Forest are free from the start, and new dioramas are added over time. ■ Collect star medals, grow your tank While you watch, star medals now and then settle quietly on the sand. Each one you pick up is worth 5 medals, up to 25 a day, and you can use them to make dioramas, backgrounds, tank shapes and floating items your own, one by one. If you like, you can choose to watch a rewarded ad to get a few more medals. Ads never appear on their own. ■ Clione Premium With Premium, every diorama, background, tank shape and floating item is yours to use, along with up to 7 clione and 4 Premium-only music tracks.
