Shark Week? Aunt Flo? Or Granny's stuck in traffic? Which one's your favourite? Women's ovulation concerns men more often than we care to admit. It's a topic typically discussed in hushed tones during a conversation with your spouse, daughter, or colleague. Imagine having an app that keeps you one step ahead of things with all the women in your life. It would inform you when her period or ovulation is due and even give you a heads-up on the mood you're about to encounter. Introducing an app designed to help men organise their female-centric world. Each woman has her own information page, allowing you to track her cycle and related moods. You can even save important details, such as shoe or clothes sizes, to avoid awkward situations while shopping. Furthermore, the app includes short articles (currently available in Hebrew) to assist you in navigating life with women.

Verdict
The clearest difference is update cadence: D at every 5 days against RedAlert's every 4 weeks. RedAlert's advantage is iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
