Hi Product Hunt! 👋 I’m a cyclist who spent too much time wondering why my GPS was showing impossible 25% grades on a steady hill. I realized that GPS noise was ruining my data, so I built Slopy. It started as a personal tool to 'clean' my weekend rides, but I realized fellow cyclists and hikers might find it useful too. It’s a native macOS app, focused on simplicity and precision. I’ve decided to launch it as Pay-what-you-want (starting at $0) because I want to give back to the outdoor community. I'd love to hear your feedback on the filtering and the interface! Happy climbing! 🏔️
