What's New in KartaView

5.9.5

June 3, 2026

Fixed a rare issue that could cause the same clip to appear more than once when uploading a trip with multiple videos. Upload now finishes cleanly at 100% before the screen closes, so you can see when it's truly done.

Upload issues

The latest version of this app still has had issues uploading tracks. Often time recordings are lost or will say 100% finished but then never get uploaded, or disappear forever. Grab has really let this app go to hell. It worked fantastic when it was OpenStreetCam under Telenav!

Can’t login

It used to work fine but now I can’t login using my open street app account.

Upload videos discontinued

I can’t upload because it on error

Use Mapillary As A Better Choice

The App Is Useless. Use Mapillary Instead

Uploads buggy - beware!

This version gives me a terrible data loosing bug where uploads will quit abruptly midway though uploading, loosing your pending uploads in the process. Developers not replying to emails about this issue, seems to be a severely under resourced project at this point. It’s too bad Grab is really letting this app go by the wayside ever since they acquired it from Telenav. Check out Panoramax instead!
