I have to take this into account, so I know what you're talking about. Sometimes the sewer is clogged and needs to be cleaned. By the way, you have this situation. I can advise service on this site https://www.draincom.ca/ with drain repair, so I immediately call this service.

I used OurHome and it does this okay but I hate that it isn't clear in the app someone else has completed the task recently.

PLEASE DO IT!

I'm still looking for a great app to handle roommate chores. My ideal design: As a group, my roommates and I come up with a list of all of the chores that need to be done. Then we assign a point value (or $ value) to each chore that is a reflection of a) How long it takes to do this chore, b) How much people generally like/dislike doing this chore, c) How often this chore needs to be done. For example, chores that are more disliked and need to be done more often would have higher point values than those that people like doing more and/or need to be done less frequently. We would then set these all up in Splitwise, and then people would log chores as they did them and automatically accumulate points/dollars. Different groups could then do as they like. Some might just use this as a way to make chores transparent (and thus hopefully shame laggers into doing more), or roommates could have a monthly/quarterly payout in which roommates have give/receive money/points depending on whether they are under/over the average.
