## What is Apex Run?

MAKE YOUR RUNNING DATA COUNT.

The ultimate analysis tool for data-driven runners. Unlike apps that just track your next run, Apex Run instantly unlocks the value of your entire running history — synced with Apple Health, with professional-grade insights.

INSTANT HISTORY & CORE METRICS
• Zero Cold Start: The day you install, your whole running life is already here — lifetime stats, heatmaps, and progress trends, synced from Apple Health.
• Best Efforts: Your all-time bests across every common distance, found and tracked automatically.
• Comprehensive Metrics: Pace, Cadence, Stride Length, Power, VO2 Max, and Zone2 Pace.
• Map Styles: Color-code your full-screen route by Heart Rate, Pace, or Elevation — Standard or Satellite.
• Personal Achievements: Earn exclusive badges as you hit new distance goals.
• Quick Navigation: Jump straight to any past workout with the calendar picker.

ADVANCED ANALYTICS SUITE
Elite-level metrics used by professional coaches and athletes:

[ MORNING RECOVERY CHECK (NEW) ]
Know whether to push or hold back before you lace up. Apex Run reads your overnight recovery signals from Apple Health and compares them against YOUR personal baseline — no black-box score, every number auditable.
• Recovery State: A clear morning readout — Optimal, Recovered, Compromised, or Fatigued.
• Personal Baselines: Track HRV, Sleeping Heart Rate, Sleep Duration, and Restorative Sleep against your own 30-day range, with drill-in trends.
• Daily Training Guidance (Pro): A concrete intensity recommendation for today — from a key session to an easy Zone 2 run to full rest.
(Requires an Apple Watch worn during sleep.)

[ RACE PREDICTION & PLAYBACK ]
• Shadow Runner (Pro): Race the fastest version of yourself on any route you've run before — see where you're gaining or losing ground.
• Race Time Prediction (Pro): Personalized finish-time estimates for your next 5K, 10K, Half, or Full Marathon.

[ SCIENTIFIC TRAINING LOAD ]
• Training Status (ACWR) (Pro): Monitor your Acute:Chronic Workload Ratio.

## Version history (last 5 releases)

### 1.8.2 — 2026-08-11

Your watch stopped mid-run? Put the session back together. When a watch is stopped and restarted, one run gets recorded as two short efforts — distance split, time split, and an average pace that reflects neither. Open the first one, choose Merge Next Run, and Apex Run rebuilds it as a single session: one route, one set of splits, best efforts that span the break. Your originals stay in Apple Health, and deleting the merged run brings them back.

Also in this release:
• Splits on imported and manually added runs appear at once instead of taking seconds.
• Delete a run could crash the app on the way back to your summary. Fixed.

### 1.8.1 — 2026-08-06

• The Profile tab shows how many days remain in your Pro trial
• Map markers now appear in your language
• Distances no longer wrap in the run list
• Small fixes and wording corrections throughout

### 1.8.0 — 2026-07-29

This update adds a whole new way to train — before you even start running.

NEW: Morning Recovery Check
Apex Run now reads your overnight recovery signals from Apple Health and tells you whether today is a day to push or hold back.
• A clear daily state: Optimal, Recovered, Compromised, or Fatigued
• HRV, Sleeping Heart Rate, Sleep Duration, and Restorative Sleep — each tracked against your own personal baseline with 30-day trends
• Every number is transparent, compared to YOUR normal — no black-box score
• Pro: a concrete training recommendation for the day, from key session to full rest
(Requires an Apple Watch worn during sleep.)

NEW: Custom Heart Rate Zones
Build training zones the way the pros do. Generate your zones from Max HR %, Karvonen (Heart Rate Reserve), or Lactate Threshold (LTHR), then fine-tune any boundary down to the exact BPM. Changes re-analyze your entire running history instantly.

NEW: Choose Your Share Map Style
Pick how the map looks on your shared run cards — Standard or Satellite — right from Settings.

### 1.7.0 — 2026-06-09

This major update introduces two features designed to celebrate your race day victories and track your long-term aerobic progress.

- Your Digital Trophy Room
Every finish line deserves to be remembered. You can now mark any run as a race and upload your medal photos or race-day moments directly from the page. Your personal Race Wall will showcase all your races and memories in one place — making it easier than ever to relive your proudest achievements.

- Zone 2 Pace
We've calculated Zone 2 Pace for a single run, and add a long-term progression chart for your "Pace at Zone 2" in Trends view. Visually track how your aerobic efficiency improves over time, and watch your pace get faster while keeping your heart rate low!

### 1.6.1 — 2026-05-12

A minor update with a handy new feature and a few bug fixes to keep your analytics running smoothly!

• 5km Splits: You can now view 5km split statistics directly in the Run Details page for a better breakdown of your long runs.
• Widget Fix: Fixed an issue where the "Latest Run" widget was occasionally not updating with your most recent data.
• Monthly Report Fix: Resolved a rendering bug that caused GPS route maps to display incorrectly in your monthly summaries.
