Island Waste Management, which handles compost and recycling pickup on Prince Edward Island, has an mobile app that, among other things, can send me alerts about which cart to put at the curb when.

Our pickup day has been Tuesday since time immemorial, but last night I got an alert that waste had switched to Thursday, with compost remaining on Tuesday.

I called IWMC, confused, only to learn “the app is being worked on,” and Tuesday remains the day for both.

So if the app is telling you something different than you expect, double check to make sure — 1-888-280-8111.
