“I switched from Flo after the data scandal. Cythr gives me the same features without selling my most intimate data. It's refreshing to use an app that actually respects privacy.”
“The AI Smart Log changed everything. I just type how I feel and it logs everything automatically. No more tapping through 20 different symptom buttons.”
“The partner sharing feature is amazing. My partner can see when I'm having a tough day without me having to explain. It brought us closer.”
“Finally an app in Hebrew that actually works well! The RTL support is perfect and the translations feel natural, not machine-generated.”
“The streaks and XP system makes me actually want to log every day. It turned tracking into a healthy habit. My prediction accuracy went from 60% to 90% in two months.”
“I was paying $60/year for Flo. Cythr does more, for free. The AI features alone would be worth a premium, but they give it away. Respect.”
