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.

Works fine with my BC 16.16 over NFC. However, it only ever transfers the current ride. I usually have NFC turned off in the BC 16.16 in order to conserve battery, so it always takes forever to turn it on. Ideally, it would load my entire back log which is saved on the device itself. But I'd have to at least be able to download data from the past week in order for this app to make any sense for me.

this app making me nuts..I bought sigma rex 11.. and always have problem syncing data with phone. after ride, when I try sync data, device is connected, and in app when I press download activity, app either hangs or shows screen downloading and freezes. and on sigma, screen changes connected to searching. well 1 out of 100 tries, I'm able to sync data. you should fix your app, you guys are hurting your excellent device..
