## What is Harlen?

The app lets athletes securely link with their coach, grant permission for wearable and health data access, and keep their latest metrics available to their coach’s dashboard. Once connected, athletes can view their coach link, wearable connection status, and recent data such as resting heart rate, sleep, and steps.

Harlen is intentionally simple: the coaching workflow happens on the coach’s web dashboard, while the mobile app helps athletes connect their account, manage consent, sync wearable data, contact support, and control their account.

## Version history (last 5 releases)

### 1.0.5 — 2026-08-17

Your training program, now on your phone. See the block your coach built — day by day, week by week — and log what you actually hit, set by set. Your coach sees it immediately.

New calendar: add your own competitions, races, and time off so your coach can program around them.

Wearable connection is clearer — you can now tell at a glance whether your device is actually sending data.

### 1.0.4 — 2026-08-06

Fixed an issue where connecting a wearable could show an error even though the connection had actually succeeded. The connect screen now waits for your device to finish linking and updates on its own.

### 1.0.3 — 2026-07-24

• Morning HRV reminder — if you log HRV manually (e.g. WHOOP), Harlen nudges you at 8 AM on days you haven't logged it yet.
• Disconnect your wearable anytime from the wearable screen.
• Connection health — Harlen now warns you when your wearable has stopped sending data, so gaps get fixed instead of going unnoticed.
