Congrats on the launch. My advice is to stay away from the "Like X for your Y". Define your own category otherwise, you will end up just copying way too much of Superhumans thinking.

I definitely will need a non-analogy description. I've called it a "Call Manager" on the App Store. I'll see if I can think of something more... descriptive.

Earlier quoted context omitted.

IF (area code == my area code) AND (prefix == my prefix) AND (last 4 != my last 4) THEN SPAM SPAM SPAM ?

YES Also: if (area code == my area code) AND (number NOT IN whitelist) Basically: I have a mobile number in an area I left 15 years ago. Any call I get from there that's not one of my friends is de facto spam.

I wonder how long before AdTech uses location data change which robo-call center to choose from its aws equivalent in your area code.

Congrats on launching! One security-related question: I had looked into this area previously as a user and a security-conscious friend pointed out that systems that use call forwarding to stop the spam problem are a HUGE security risk. You’re effectively man-in-the-middling all mobile calls, SMS, etc, and if there’s some sort of compromise (or, much less likely, malicious act) on your end, all of us users will be in…

Same thought here. I have been toying with the idea of building something OSS so that people could run it themselves, for this reason. (Also I have what is possibly a common filtering case in the US that would eliminate 95% of my spam calls without blocking any relevant calls from "new" numbers. And for whatever reason, I have not seen it implemented anywhere yet.)

You may be looking for ‘WideProtect Spam Call Blocker’:

For iOS: https://apps.apple.com/us/app/wideprotect-spam-call-blocker/...

If only one or a few prefixes need match, use Hiya below. If you want all wildcard prefixes, you want WideProtect.

Most do not support the wildcard formula, this does.

https://apps.apple.com/us/app/hiya-spam-phone-call-blocker/i...

This supports area code and local prefixes (but not wildcard local prefix). Unlike Trucaller etc., the privacy policy is ok.

If you want to block all prefixes, see WideProtect above.

I want something different. I want a Lenny, but that I don't have to conference in. That step is failure prone, takes time, and usually doesn't work -by the time Lenny is on the line, the spammer has long fucked off. I want a "bot" that spews nonsense - but sufficiently plausible nonsense to keep spammers on the line - that I can activate with a single button click, at any point during a phone conversation with anyon…

Check out the Robokiller app - their answerbots do exactly what you described. https://apps.apple.com/us/app/robokiller-block-spam-calls/id...

This one also has ‘neighbor spoofing’ blocking.

Congrats, definitely going to give this a try as I get spam calls all day long! I wanted to tinker around with other phone projects what provider are you using on the backend if you don’t mind sharing ?

Let me know how you like the app! The backend uses Twilio. They have good documentation and examples, and their teams are responsive.

Until this service becomes so popular that the robocallers start deliberately working around it, I think you may only need a 1-digit PIN. I've had a service from the phone company on my landline for decades that just makes an unknown caller dial a 1 before my phone will ring, and it continues to nearly eliminate spam calls. So the 1-digit PIN can just be a "1".

Randomized "Enter X to be connected" with 0-9 is a feature several people have requested. I agree that you can probably cut most with just that.

So, a captcha :)
