Vocalove: Voice Dating
Vocalove is a voice-first dating app designed to foster authentic connections by prioritizing personality and conversation over appearance.

With full VoiceOver support, Vocalove is also built to be inclusive and accessible for users with visual impairments.

Paysplit: Split Bills
Paysplit is a thoughtfully designed iOS application that simplifies the management of shared expenses among groups. Whether it's a dinner with friends, a holiday trip, or ongoing shared household costs, Paysplit provides a streamlined solution for tracking and settling expenses fairly and transparently. Users can create groups, add individual expenses with detailed descriptions, assign amounts to specific participants, and monitor outstanding balances in real time. The app supports flexible bill splitting—either evenly or based on custom allocations—making it adaptable to a wide range of scenarios. With its intuitive interface and clear summaries, Paysplit eliminates the confusion and awkwardness often associated with managing shared costs. It ensures everyone knows what they owe and what they've paid, reducing friction and improving group financial coordination.

VoiceDate: Dating By Voice
VoiceDate, the successor of Vocalove, introduces a refreshing approach to online dating by focusing entirely on voice messaging. No more swiping or small talk—just real, human connection through the power of voice. The voice reveals personality, emotion, and intent in a way text simply can't. With VoiceDate, users not only build confidence in speaking but also learn to appreciate the authenticity and intimacy that comes from hearing someone's voice. This app was created to encourage more meaningful interactions and to help people connect in a deeper, more natural way. I truly hope VoiceDate makes a difference for its users—and I'd greatly appreciate any feedback on the App Store to continue improving the experience.

As you progress through levels, you'll earn extra time and additional chances, keeping the gameplay fast, rewarding, and addictive. RiPop is compatible with all iPhones from the iPhone 5 onward, as well as all iPad models. The app supports English, German, and Turkish, automatically adapting to your device's language settings.
