Miss a week and your fish will not scold you. It will tell you what its own week was like. Finnery is a companion for betta fish. Your betta has a character, a voice and an opinion — about itself, never about you. NINE CHARACTERS, ONE FOR YOUR FISH. From the diva to the stoic to the nitro-grandma. You choose who moves in, and from then on it speaks in its own register. TRY IT WITHOUT AN ACCOUNT. Set up a tank, let a fish move in, listen. No sign-up, no email, no form. If you want to stay, you make an account later — everything you created stays. KEEPS TRACK OF WHAT YOU ALREADY DO. Water changes, feeding, observations. Your care history in one place, without a spreadsheet and without a score. TWO FISH THAT KNOW EACH OTHER. Connect your fish to a friend's. From then on those two have something to say to one another. NOTHING IS INVENTED WHILE YOU WATCH. What your fish says was written before you opened the app. No language model runs in the background. ALSO · Multiple tanks and fish · Reminders that invite rather than nag · Aquarium terms stay the terms the hobby actually uses · No tracking, no ads · Completely free Built in Berlin.
