Reviews
What early users say.
★★★★★
"It screens scam callers … and automatically blocked them when they refused to display their name and contact information, so they won't bother me." "Affordable to me. Thank you — 5 stars."
★★★★★
"Too good — an AI call assistant app I'd needed for a long time, with AI auto-call features that are not available in every app … professional looking design … very affordable … one of the best for its price and design."

Questions
Frequently asked.
How does OsmO screen my calls?
When an unknown number calls, OsmO's AI answers in a natural voice, asks who's calling and why, and decides in real time whether to connect you, take a message, or block it as spam. Here's how AI call screening works, step by step.
Will I miss important calls?
No. OsmO recognizes urgent and important calls — a recruiter, your doctor's office, a family member — and can transfer them straight through to you, or text you instantly with the details.
Does OsmO work with my carrier?
Yes. OsmO works on top of your existing number using conditional call forwarding, supported on AT&T, Verizon, T-Mobile, Rogers, Bell, Telus and most US & Canadian carriers. Setup takes about a minute.
What languages does OsmO speak?
OsmO speaks English and Spanish today, with French and German coming soon — so it can answer and make calls in the language you and your callers prefer.
Is my data secure?
Calls are encrypted in transit and you control what's stored. You can review, export, or delete your transcripts and recordings at any time.
What platforms does OsmO support?
OsmO is available free on iPhone (iOS) and Android. Download it from the Apple App Store or Google Play.
Silence.
Your phone finally has a brain.
