SIGMA DATA CENTER Customer Insights

1. Anybody any ideas anyone? Cannot set Sigma Cloud account, e mail address taken, even though never registered!!! Tried another e mail, that was set up a couple of months ago, the same!! Asked for password reset, cannot as not activated, this is for both e mails!!! Initially Windows 10, then Android tablet and then Android phone..... This is appalling, the GPS was a gift and works really well, very impressed, but the cloud software registration is unacceptable.

2. P.s. I've been using sigma device for the last 13 years.Update to below: Quick reply, but 3 days later their Cloud software has not been fixed.

3. If resolved will amend, but incredibly difficult in data center to find a contact e mail!Unable to download the new firmware for my ID FREE watch any help would be greatful,I've tried downloading it via laptop connection it says unable due to no Internet connection but it is definitely connected.So Far No Good.

4. You guys make best bike computers and idea of desktop software with local database is also great, but you must start make better software if you dont want to disapear from market.The app didn't open at all.

5. Leider fehlt die Möglichkeit tracks zu importieren (gpx, ...). Das wäre z.B. für den Urlaub wichtig wo man selten einen Mac oder Windows PC dabei hat.The app is very nice and useful except a weird calculation error.

6. The track menu always shows less elevation change than in the activity menu.

7. And then i also lost the ability to connect any new devices (Android 8.0) because the appropriate menu functions just disappeared.

8. In general, it looks heavy and all animations (even simple scrolling) shows as they are in 15-20 fps, like in slow browsers.

9. An activity recorded with a Rox 10 shows e.g. 600 m uphill in the activity - value menu.

10. From some point of time it stopped work with RC MOVE (the same situation as with SIGMA LINK).

11. I like the device itself, but the software seems to be is not developing.
