### 4/5 — Change Default Chart Metrics for all subsequent views

*2026-06-28*

Is there a way, for example, to change the Chart Metrics one time and have those default settings applied every time I open another workout (e.g. ALWAYS start off showing graph with Split/GPS, Stroke Rate, and Distance)? If not, please add this to your list of highly desired features. It’s tedious to have to change them to my own preferences over and over again

Otherwise, very good app.

### 4/5 — Works well

*2026-04-02*

Appreciate being able to connect Garmin HRM heart rate strap

### 1/5 — Doesn’t work

*2025-10-02*

In October 2, again this app cannot be opened.

### 5/5 — Rowing is rowing

*2024-06-08*

And this app makes rowing more data driven. That is good. It does it well.

### 4/5 — Erstnutzung

*2021-07-29*

Für eine kostenlose Applikation zu einer ca. 400€ Trainingsaufzeichnung, finde ich die Anwendung und Darstellung gut strukturiert.

### 1/5 — Idee gut aber nur auf dem Papier ...

*2021-06-06*

SpeedCoach ist leider nicht mit dem iPhone12 zu verbinden, daher sinnlose App ... aber auch die Investition in die Trainingsversion des SpeedCoach macht keinen Sinn, da diese App kein Daten übernimmt 😡😡😡 Fazit: einfacher bleibt es mit Garmin Uhren Trainingsdaten zu führen ... NK ist nicht zu empfehlen !!!

### 5/5 — Great App!!!

*2020-04-17*

This app was amazing! I totally recommend it!

### 2/5 — Great Idea but not currently functional

*2018-11-20*

Primarily connection issues.. even following closely in speed boat, app and speedcoach keep dropping out. Quite frustrating.
