Keeps crashing. Was working well before about a week ago and now crashes often, and I'm prompted to submit bug reports often. Sometimes I can't even open app. Also lots of my details under My Treks have self-deleted and it won't let me enter them back in. Hopefully the bug reports will lead to a fix, otherwise i'll have to look for a different cta app, which would be too bad because it was really useful before. I have a samsung galaxy a32 5g.

Hi Margaret, I've reviewed your bug reports. It appears data has been corrupted somehow and failing to load. You can try to clear the app data to start fresh which should prevent the crashing. Please reach out to me at if you need further assistance. I hope that helps.

Train times are inaccurate. They show the trains positions pretty far off from reality and compared to other apps. Map functionality is especially inaccurate.

Hi Shane, sorry you are finding the data inaccurate. All data comes from the respective transit agency and should match any other app. Please email me for help if the issue persists. Thanks.

Pretty good overall! Considerably more accurate than Google for ETAs! Not so easy to use as it mught be. I just tried to get arrival times for the Red Line at Wilson and could only get bus times from Quick Treks

Hey Barry, thanks for the feedback. Please reach out at to discuss. If you have suggestions to make the app easier to use, I'd love to hear your ideas! I just tried tracking the Red Line at Wilson and had no issues, so if you're having a problem, I'd need more details to investigate and fix it for you! Hope to hear from you!
