Slopy

Are you tired of looking at your hard-earned cycling or hiking data only to be frustrated by noisy, jagged elevation profiles that hide the true story of your effort? We understand that frustration completely. That is why Slopy was created; it is a precision GPX and elevation analyzer built specifically for macOS users who demand accuracy from their outdoor adventures. This isn't just another data viewer; Slopy employs advanced mathematical techniques, specifically the powerful Savitzky-Golay filtering method, to meticulously clean up the often erratic elevation readings captured by standard GPS devices. Imagine seeing your climb profile not as a chaotic scribble, but as a smooth, clear representation of the actual gradient you conquered. This level of clarity allows you to truly understand your performance, identify subtle changes in steepness, and appreciate the real challenge of a route without the distracting noise of minor GPS inaccuracies. It is about getting the unvarnished truth of your ascent, presented beautifully on your favorite Apple device.

What sets Slopy apart is its dedication to performance and your privacy. As a native and incredibly lightweight macOS application, it integrates seamlessly into your workflow without bogging down your system. The control you have over the analysis is intuitive and immediate; you can adjust the smoothing in real time, seeing how the data transforms right before your eyes until it perfectly matches your memory of the terrain. Crucially, because this is built by an outdoor enthusiast for the community, we prioritize your data security. Every calculation, every filter application, happens 100% locally on your machine. Your routes, your efforts, and your personal data never leave your computer, offering peace of mind alongside unparalleled analytical power. Whether you are a serious cyclist reviewing segment performance, a hiker planning future ascents, or just someone passionate about accurate mapping, Slopy gives you the tools to extract meaningful insights.

Once you have refined your track to perfection, Slopy makes sharing and further analysis simple. You have the flexibility to export your cleaned, accurate data into widely compatible formats like SVG for beautiful visual representations or CSV for deep dives into spreadsheets and other analytical tools. We believe that powerful tools should be accessible to everyone who loves the outdoors, which is why Slopy is offered on a "Pay what you want" basis, making world-class data analysis available even if you choose $0.
