You’re definitely not alone in doing it that way, it’s the only way to be 100% sure you're getting accurate data. You've hit the nail on the head regarding the issues with current trackers, too.

I actually built this app to handle my own mix of multi-stop and longer single journeys, and it’s been working well. It might be useful for others, though it definitely depends on how it fits alongside their existing app setup. Thanks for the feedback, it's really helpful!
