Useless for now. CAT PLEASE FIX, this is people’s livelihood on the line!!!!!! ### 1/5 — Continues to be worthless *2025-10-08* I know the standard response from CAT is coming….Thank you for your review, blah, blah, blah. Yet they can’t or won’t fix this worthless app. It’s a continuous loop of signing in, signing up and no working pages.

Just pulls up the app and stays on the initial screen. ### 1/5 — Unusable at best *2025-09-04* Have tried uninstalling and reinstalling multiple times, tried different logins which I know work, it either gets stuck in a login loop or if you manage to get past that and try to download a machine it gets stuck at 90% and will not complete. In the past when it did work everything was mixed up making searching for things impossible. **Developer response:** Dan, thank you for your feedback.
