With Typus you can easily and quickly document your measured values. Typus provides you with a clear dashboard that allows you to keep track of your water quality at all times. The special feature of Typus? You can also enter events in your tank, for example new fish or coral stocking, but also incidents such as algae growth or the use of a new salt. This helps you to better understand and document the relationships in your aquarium. Typus also helps you to document your dosage of the individual elements, so that you can always keep an eye on everything concerning your water quality. Current features: - keep track of your water quality with our easy-to-read dashboard - set the optimal range for each parameter. Typus gives you a hint if a measured value is outside this range. - keep track of various events - display events and measured values in a clear graph and recognize new correlations - document your dosage and put it into a context with your measured values - choose the right unit for you, for example salinity or salt density - create multiple tank profiles for different aquariums In the future we will add more features to Typus, some of which will require a monthly subscription. But don't worry, the above features of Typus will always remain free! Do you have a problem with Typus? Then write us via the support form in the app. We will be happy to help you at any time.
