I love how accurate LH level detection is and the automatic adjustments to fertility scores. I also like the messages of what to do next depending on the LH level results. I would give a 5 star rating if the app was setup like the app shown on the website. The app is below basic and needs some sprucing up. I’m surprised at the technology function with the app in comparison to the analyzer. The analyzer is amazing and functions as advertised in contrast to the app. I would assume the same effort put into the analyzer specifically would be the same as the app. The product would be beyond fantastic if all areas were functioning properly.
