FizzCounter

FizzCounter is a simple offline CO₂ cylinder tracker for households that make sparkling water with compatible home sparkling-water makers.

Set up your equipment, start a new cylinder, log sparkling bottles and check how much CO₂ may remain. The app helps you track bottle counts, refill or replacement costs, cost per bottle, cost per litre and real cylinder weigh-ins.

FizzCounter is designed as a practical household tool. Instead of relying only on broad manufacturer litre claims, it uses your own bottle logs and weigh-ins to keep future estimates better aligned with real use.

The app includes a guided Fizzing Assistant for supported Terra-compatible setups. The Assistant walks you through cold-water preparation, attaching the bottle and following timed carbonation prompts. Assistant sounds and vibrations can be turned on or off independently in Settings.

Features:

• Track an active CO₂ cylinder
• Log sparkling bottles manually
