A question, a problem with coins or feedback. Write to us and we will reply by email.
Do I need an account or internet?
No. Underglass has no login and works offline. Your tanks are saved on your device.
What is free and what costs coins?
Common species, plants and decor are free. Rare fish, color strains and tanks from 120 cm up cost coins. You start with 100 coins and can claim 10 more every day.
My coins are missing on a new device.
Coins and unlocked items are kept in iCloud Keychain. Turn iCloud Keychain on and they follow you to a new iPhone or iPad and survive reinstalling. The App Store Restore Purchases button cannot bring coins back.
How do I save or share a tank?
Open the tank menu in the editor. Photo saves a picture, Video records 10 seconds, and Share tank sends a file another Underglass can open. To open a file, tap 開啟水族箱檔案 in My tanks.
Does my tank keep growing when the app is closed?
Your Living tank grows plants over real days and weeks, even when the app is closed. Plants need an occasional trim. The Home Screen and Lock Screen widgets show how it is doing.
How do I rename or delete a tank?
Press and hold a tank in My tanks. Deleting the app removes the tanks stored on your device. Coins and unlocks stay in iCloud Keychain.
How do I contact you?
