Monthly fees for customers to do much of the work

So the customers report the numbers that get to their phone (basically doing lots of the work) and you guys charge a monthly fee. Seems like a bad deal to me. Just what I need another constant drain on my account. Has anyone considered doing maybe a $$ a month for 12 months and then you own the app type thing. No of course not. But seriously in this case a monthly fee is basically paying for nothing but someone to see if multiple people reported a number and update a database with the numbers your customers are reporting (easily automated). I like the idea but I am sick of monthly fees already. Apple does most of this already for its customers and isn’t charging a fee for it. Your app just went through my phone and changed all the numbers that were reported by Apple as scam numbers to saying you did something about the call. But you did nothing as many of those calls came well before I installed the app. I personally would rather just push cancel when I see possible scam number then pay a monthly fee to have an app do the same thing.

Impossible Task

UPDATE IN RESPONSE TO DEVELOPER RESPONSE. Actually my app settings have always been set to access my contacts and that has made no difference to my original review. I already reached out to the support team and there were no other suggestions other than to keep adding people myself. I know spoofing is very challenging and I think the telecoms and government need to come down hard on those doing that. The telecoms can with the data they get from each call so I suspect they don’t because they just don’t want to spend the money to develop the process. Instead they figure we will put up with it because we really have no choice. I have over 800 individual numbers manually blocked on my phone. I am not going to waste time helping an app that actually doesn’t work as it should when it won’t block numbers not in my contacts. I just cancelled my renewal because it just isn’t worth the money when it just doesn’t work. It looks like most of the nuisance calls I receive are spoofed numbers and this app doesn’t catch them. It does a fine job of identifying spam and telemarketers but that is less than a third of the nuisance calls. At first I was individually blocking those calls but that has become ridiculously time consuming. The spam texts process would get a 2. It isn’t really designed to deal with all the texts people get these days that are legitimate notices. I am not sure any app can effectively deal with the mess of spamming. On the up side it is easy to install.

Developer Response ,

Thank you for the feedback! Spoofed calls are difficult to deal with, which is why our developers have added a feature to share your contacts with the app. You can reach out to our team at, we'd be happy to walk you through some options to ensure the app is working to its full capacity.

Good App Overall

Edit: I contacted support and had decent assistance but nothing worked (even the test calls still came through). After deleting and re-adding the app a 3rd time it suddenly worked. I’ll raise my review to 5 star since it’s more than likely an Apple issue than their app. The app always seemed to work fine so I’m not sure what broke it but I’m glad to have my sanity back.

I’ve been Googling numbers I don’t recognize for the past year and usually get generic results so I assume the robocall is a new number. No biggie, move on and assume the app is working fine. Now in the past month I’m getting hits on Nomorobo’s own site telling me it’s a robocall and yet it isn’t being flagged or stopped. These are numbers that were listed on the website MONTHS ago and I keep my app open and updated. Just today I got ANOTHER 4 calls that Nomorobo knows about and have gotten at least 10 or 11 in just the past week. Save your money, this app isn’t going to stop any robocalls.
