Nobody else has commented, so I'll give you my opinion...
You have a steady but smallish number of downloads. Given the bad ratings of your app, I think that indicates that there are people who want something like this - enough that 150 people per week will download a 1-star app.
If you're just sick of this app, then either abandon it or maybe sell it for some small amount of money to someone who wants to give it a shot.
But if you're just sick of maintaining something that's going nowhere, then make it go somewhere. There's some interest there. Listen to the complaints. Pivot. Clean it up a bit and make it $0.99 instead of free.
