I built this website because we kept forgetting to take the bins out. When we remembered, I still forgot which bins went out on which days. You can get this information from the council website, but it's hidden behind a frustrating multi-step form that it quite slow and doesn't work well on mobile.
I impersonate you and pretend to visit the council website on your behalf. I then read the bin(s) information back.
You can bookmark your specific bins page and manually check it whenever you're wondering when your next collection is.
Alternative, if you use the calendar feature (recommended), your calendar tool will periodically refresh the calendar (usually daily). I personally use this feature to avoid forgetting the bins!
