The measurement data can give you a lot of information. It can show you when your fermentation is not active anymore so you can keg your beer. But you can also use the temperature data to monitor your dry hopping temperature, and correct it if needed.

Next to real time data, Float’s data can be use to check historical data from older brews in oder to re-produce these.

With a My Brewbrain account you can track your brews everywhere! Export your data or look at what other people are brewing. Easily link your data to other tools such as Brewfather and Grainfather.
