Vienna Startup Ovulyx Launches Couples-Focused Cycle Tracking App
Stefan Renzler, a Vienna-based developer, has launched Ovulyx, a cycle tracking app designed for couples, allowing both partners to view cycle phases and share an experience log to discover what helps during each phase. Users can track mood, energy, symptoms, and bleeding, with predictions for period, PMS, and fertile window. Partners connect via an invitation code and see a dedicated view with supportive actions. The app also supports trying for a baby and menopause, and allows import from Flo and MyNFP. Available on iOS, Android, and web in 29 languages across 152 countries, it offers a 30-day free trial, with Premium at €4.99 monthly or €49.99 yearly. Prioritizing privacy, data is stored in Western Europe under GDPR, and the app does not sell data or use health data for advertising. Ovulyx competes with Flo for Partners and Clue Connect.
Niche consumer app launch with limited direct relevance to the AdTech industry, though it touches on health data privacy considerations.

Vienna Startup Knightify Launches Privacy-First Relationship App Pulse
Viennese software studio Knightify FlexCo has launched 'Pulse,' a privacy-centric B2C relationship application designed for couples. The app reads biometric and activity metrics—such as sleep patterns, heart rate variability, and resting heart rate—directly from Apple Health or WHOOP, translating them on-device into human-readable updates. To prioritize data privacy, raw health data is processed entirely on the user's iPhone and does not leave the device, while messaging and shared memories are encrypted via Apple's iCloud infrastructure. Pulse is currently free to use, with plans to transition to a subscription-based model. Founder Amirali Khoshneviszadeh emphasized that the application will remain completely ad-free, refusing to sell personal user data to advertisers.
