Hint.jpg OCAD Sketch App - Beta Release. We have tested the OCAD Sketch App intensively and successfully on various devices over the last few weeks. However, errors may still occur. Therefore, we recommend to create regular backups. If you have any feedback, please use the Share Feedback tool in the General Settings.


The OCAD Sketch App complements the desktop version of OCAD. It is designed for mapping in the field – both for new mapping as well as revisions, feedback from course planners or map reviewers. Drawing pen, different colors and line widths and eraser enable fast and ergonomic sketching. GPS routes can be tracked and the compass can be used to adjust the map orientation. Map projects are transferred from desktop version of OCAD to the OCAD Sketch App and synchronized back after mapping. The download and use of the app is free of charge.
