There is a learning curve but overall I'm glad I spent the money. I bought additional sea water pool tests from the app and they work fine too. Things I would like to improve is the improved ability to export data. It would also be great to be able to set goals. I'm constantly refreshing myself about what value range I'm trying to stay in.
