Livecaller

An idea so obvious you'd wonder why it hadn't been done before...! (Until you recall how much Apple gatekeeps its platform and then you'll understand why!)

Hi Product Hunt, I’m Ken 👋

Fifteen years ago, I had a simple dream: bring real-time caller ID to iPhone.

For over a decade, it wasn’t possible. Apple simply didn’t allow it.

That finally changed with iOS 18.

And today, we’re launching Livecaller, a real-time caller ID and spam-blocking app for iPhone. No contact uploads, no account required, and no creepy tracking.

I’ve built multiple apps before (you may remember my previous launch, Calendar.AI), but this one is different.

This is the product we’ve been waiting over a decade to ship.

Here’s what Livecaller does:

• Instantly shows you who’s calling before you pick up

• Blocks spam, scams, and robocalls

• Doesn’t upload your contacts or require an account

• Lets you search unknown numbers (4B+ number database)

• Bonus: Personalize your caller ID name with an emoji — just for Product Hunt

If you’re thinking, “Doesn’t iPhone already do this?”

The answer is… no, not really.

This is the first time Apple has allowed real-time lookup of incoming calls on iOS.

And unlike other apps, we don’t need your address book, subscription, or personal info.

We built Livecaller on one principle: you shouldn't have to trade your privacy for basic utility.

• We never upload your contacts

• No account is required to use the app

• We use homomorphic encryption to match numbers — meaning we never “see” or store the actual phone numbers during the lookup

• You can opt out of our database anytime: 👉 https://www.livecallerid.com/opt-out

Privacy isn’t a feature. It’s the foundation.

On behalf of the team, I’m genuinely excited to invite the Product Hunt community to try Livecaller and tell us what you think.

We’ve been heads-down building for months, and your feedback today will help shape what’s next — from smarter features to more personalization.

Thanks for checking us out 🙏

Hey Product Hunt!

I’ve spent over 6 years working in the Caller ID space, all while being a lifelong iOS user.

I can’t tell you how many times I helped build powerful Android caller ID apps, thinking, “Why can’t we just do this on iPhone?”

The answer was always the same. Apple didn’t allow it.

That finally changed with iOS 18, and we didn’t waste any time.

Livecaller is the product I’ve wanted on my phone for years. It shows who’s calling while the phone is still ringing, blocks spam, and does it all without uploading your contacts, bombarding you with ads, or charging you anything.

It’s completely free.

If you’ve ever answered a call and regretted it, this one’s for you.

Appreciate everyone checking it out. It means a lot to finally share this.

Looking forward to answering your questions today!

Ever since I switched from Android I was missing such app. Very exciting

I'm sometimes really looking forward to tools like this. There are so many harassing calls these days, especially a lot of calls that look very legitimate. Also, I wonder if in the future there will be a tagging feature, where everyone can contribute and tag a number?

Congrats on launching Livecaller! 🚀 The privacy-first approach is impressive. How does Livecaller differentiate between legitimate calls and spam, especially with numbers not in the database? This feature could be a game-changer for many users. Excited to see its impact!

This is such a great solution for iPhone users wanting better call management! How does Livecaller ensure the accuracy of its caller ID and spam - blocking features over time as new numbers and spam patterns emerge?
