Run Analysis
Every run, dissected. View your route on an interactive map with 2D and 3D playback, overlay pace, heart rate, or elevation color-coded on the route, and switch between standard, satellite, and hybrid views. Dive into 15+ metrics — including cadence, stride length, running power, vertical oscillation, and ground contact time — plus splits, heart rate zones, and pace zone distribution.
Smart Insights
10 personalized insight generators automatically surface what matters from your training history: consistency streaks, VO2 Max trends, training load alerts, pace improvements, monthly volume comparisons, and more. Cards are ranked by relevance and refresh on every visit. Plus a shareable monthly report covering key stats, personal bests, and training analysis.
Personal Records
Apex Run automatically calculates your best efforts at standard distances — 1K, 5K, 10K, half marathon, marathon — using a sliding window over your full Apple Health history. Track your top 10 all-time performances per distance. The race predictor estimates your finish times using a hybrid of recent training data and personal record history, with a confidence indicator.
Runner's Toolkit
Practical tools built into the app: a pace calculator that derives any third value from distance, time, and pace; a quick unit converter between speed formats; a gear tracker that automatically accumulates mileage on each pair of shoes; and configurable heart rate and training pace zones based on your max HR or recent race results.

Developer Diary
Notes from the track
I’m a runner who builds tools I wish existed. Here’s what I was thinking when I built some of these features.
June 2026
Running slower, getting faster
MAF training theory says run slow enough and your easy pace gets faster. I already had the heart rate data. I just needed to look at it differently.
May 2026
The photos were on my phone. The run was in the app.
After crossing a half marathon finish line, the chip time logged automatically, the GPS trace was perfect — and the finisher photo was somewhere else entirely. Trophy Room puts them back together.
May 2026
Stolen from the race report
Race reports have always shown 5km splits. I've been reading them for years without thinking twice about it — until after my last half marathon, when I finally thought: why don't we have this in Apex Run?
Feature Requests
What should I build next?
I’m a solo developer and an avid runner. Every feature in Apex Run started from a frustration on my own runs — or an email from someone like you. I read everything and take ideas seriously.
