About this app

SIGMA LINK enables you to download your trip data and transfer settings to your bike computer with your mobile phone.

With the models BC 14.16, BC 16.16, and BC 23.16 this works by using the NFC antenna. NFC is an international standard for wireless communication between devices on very short distances. Just put your compatible smartphone close to your BC to transfer the data.

The ROX GPS 11.0 connects to the App via Bluetooth Smart. With the connection of ROX and SIGMA LINK you can:

- have a look at your tracks
- share your activities in Strava, TrainingPeaks, 2 Peak
- see incoming calls on your smartphone screen during the training (smart notifications)
- download tracks from GPSIES and transfer it to ROX GPS 11.0

The direct communication with NFC and Bluetooth only applies to the bike computer models named above. However, you can transfer data of older SIGMA computers from your DATA CENTER to SIGMA LINK by using the SIGMA CLOUD.

If you need some guidance for NFC or BLE. Check our tutorial here:

Ratings and reviews

I like the app and ability to download from my Rox 11 GPS and have it auto upload to Strava but the latest release seems to have many bugs and issues. 1. Blanks (doesn't close) any other app I may have open when open at same time. Very frustrating. 2. Keeps kicking me out while trying to rename an activity after I've downloaded it. 3. Numbers in statistics pane what I thought were totals turned out to be the range for that graph selection. Not intuitive at all.

The app is no longer reading information from my bike computer correctly and is therefore practically useless. The NFC connection is established but all rides end up empty (0 km). Weirdly enough, bike computer settings are read and stored properly. I have written an email to the developers last week but haven't heard back yet. My overall impression is that the app could use a different presentation and improved functionality ( e.g. read out altitude profile from BC 14.16 STS)

From some point of time it stopped work with RC MOVE. Cannot connect the device. It just isn't seen on the mobile phone. Also, the application itself is too slow, i mean the interface. In general, it looks heavy and all animations (even simple scrolling) shows as they are in 15-20 fps, like in slow browsers (despite the powerful phone and tablet). I like the device, also have bike computer (BC 23.16) but the software seems to be is not developing. P.s. I've been using sigma device for the last 13 years.
