Frank Nanninga's profile on Product Hunt

About

Indie developer and Apple enthusiast with a passion for crafting native apps that solve everyday annoyances. My latest project, Coffee in the Sun, was born from a personal frustration: never being able to find a terrace that was actually in the sun. I believe in building high-quality software that feels right at home on iOS, iPadOS, and macOS, with a strong commitment to user privacy and fair, one-time purchases. Excited to be part of the Product Hunt community and share what I'm working on!
