Yesterday I tested out the https://indoorco2map.com / #IndoorCO2MapDataRecorder #Android app functionality for uploading data from public transport! 🚂✨
I _think_ it worked...!
I still haven't had chance to look into whether there's a way to upload data async (later, after recording) - this would be handy for times when I can't be sure of reliable connection, or if my phone dies etc.
