Who Is TraceLens For?
I didn’t want another social feed shouting about my pace. TraceLens just shows me my own runs, beautifully. I finally understand why that one hill wrecked me.
The route map with weather context is everything. I can see exactly where the headwind hit and why my heart rate spiked on that climb.
No accounts, no sharing, no pressure. I open it once a week, look at my trends, and close it. It respects that I’m doing this for myself.
Over two years of hikes, I can finally see how my pace on the same trail changed. It’s a private journal of my body, not a competition.
