Honestly, I've never been super consistent with a dedicated app kasi parang nakakalimutan ko palagi, pero a few of us tried Flo and Clue and they're pretty straightforward, both track your cycle and show safe days clearly, so it depends kung mas gusto mo ng simpleng interface or mas detailed insights. Some of my mum friends prefer Flo because it integrates better with their phones, but honestly, the most important thing is consistency in logging your period dates talaga, kaya kahit anong app, as long as you actually use it! Have you tried any before, or first time mo lang with the method po?
