Ratings and reviews

Great "one stop shop" for all your tracking needs. tons of great features and more added regularly. if you haven't yet, try the browser version as well, the "at a glance" chart tracking of parameters is a great visual. The creator is very active and quick to fix reported bugs or issues. 10/10 i won't use another app or service. Not a paid advertisement, I bought the pro version out of my own pocket to support

I've used this reef tank app to log fish, corals, and daily maintenance with ease. It's a reliable notebook and planner that helps me track water parameters, dosages, and equipment checks, while presenting a clear history of progress. The developer's responsiveness is stellar -issues are addressed quickly and improvements are proactive. A must-have for organized, well-suppor ted reef hobbyists looking to keep their tanks thriving.

Excellent app, very intuitive with the export report that can be loaded into AI. Great communication from the creator. Would be great in the future to be able to link to testing software like the Hanna app to auto sync results
