Hi Product Hunt! I’m Sandra, and I built TerrainIQ on my own. Some days my usual runs or walk felt way harder and my tracker just showed a slower pace with no explanation. So I built an app that explains it. On my last hike it said conditions were +21% harder: +6% from heat and +14% from a 5% grade. My 25:00/mi pace was worth about 31:09/mi on a perfect day. What it does: • Effort-adjusted pace from heat, humidity, wind, air quality and slope • A short AI briefing, read aloud, when you start • Live slope graph and elevation gain ahead • Heat, allergen and severe-weather alerts • Keeps tracking with your screen locked • No account, and your activity history stays on your phone It’s Android only for now. Pause/Resume is next on my list and more to come. I’d love to know what would make it more useful for your hikes, runs or rides!
