Solo Android Developer of SmartSave

About

Hi, I’m Karsten! 👋 I’m an independent Android developer with a passion for building high-quality, privacy-centric apps. I believe that personal finance data belongs on your device, not in the cloud. That’s why I created SmartSave—a goal manager that is 100% offline and features a unique 'Self-Credit' system to help people reach their dreams. Always happy to chat about Android dev, Kotlin, or data privacy. I'd love to hear your feedback on my latest launch! 🚀
