## What is NK LiNK?

The NK LiNK for iOS app connects to your SpeedCoach GPS to download workout data to your smart device. View your performance over 100m/.1mi/30s intervals inside the app, and also export selected sessions to .fit or .csv format. Import your .fit files into Strava, Endomondo, Training Peaks and other popular workout logging and mapping programs, or open your .csv files in Excel or other spreadsheet applications to see the full stroke by stroke details of the session. All downloaded sessions are saved on your smart device allowing you to safely clear your SpeedCoach memory and record new sessions.

Quick Look:
•	Download, view and analyze SpeedCoach GPS workout data down to the interval level inside the LiNK application
•	Export selected workouts to .csv or .fit format and email or save for record keeping and analysis
•	Get alerted to available firmware updates for your SPC and install them wirelessly 

Important: 
•	Compatible with SpeedCoach GPS2, SpeedCoach SUP2, and SpeedCoach OC2.
•	Training Pack is required to connect to the app and download stored sessions.

### 1/5 — Stürzt ab

*2022-10-22*

Sobald man seinen SpeedCoch verbunden hat, stürzt die Appsofort ab. 
Dadurch leider nutzlos

### 1/5 — Buggy and don’t bother doing anything with the data

*2020-02-17*

Worked okay until the memory was full on my speed coach and I had to erase all. It now won’t connect and when it does say connected it won’t import any of the new workouts. There is no support for this specific issue aside from check firmware. Have and not worked
Also disappointing for a premium product that NK doesn’t play nicely with other apps such as Strava. I get the same information from my Garmin watch, with free graphs and the key word is “easily” syncs with third party applications
