Together is
how we call.
How often do you answer the phone only to hear an unwanted sales pitch? Or miss an important call because you don't recognize the number? Calmido solves this. Our app ensures you only get calls that actually matter.
What we do saves you time and gives you peace of mind.
Calmido builds apps that:
- Distinguish genuine calls from spam
- Provide useful information about who's calling
- Help you decide which calls to take
Why Calmido?
We noticed that phone calls were becoming increasingly unpleasant.
Spam, aggressive sales, unknown numbers. At the same time, we were missing important calls because we'd become cautious. There had to be a better way.
How it works
Is it spam? A business? A doctor?
When someone calls you, you immediately see what other users report about this number. You decide whether to answer, but with the right information.
Our approach
We believe calling should connect people who matter to each other.
That's why we built Calmido around community -- users help each other by sharing information about calls. Our calling app is intelligent yet simple, without complicated menus. Together, we're making the phone a tool for meaningful connection again.
Calmido team
Our team is small and laser-focused on creating the best calling experience.

Data safety and privacy
Calmido values privacy and is designed with a 'privacy first' principle. We don't collect data we don't need and encrypt all data in transit and at rest. Calmido does not store private keys and therefore has no direct access to personal data beyond what's absolutely required for functionality (like authentication).
We do not listen to your calls or analyse call metadata to train AI models or for any other purpose. Your conversations remain completely private.
As a result, Calmido cannot disclose personal data to any organization or institution.
Accessibility
We are committed to making our apps, website and communications accessible for everyone, including people with disabilities, by supporting standards such as WCAG. Your feedback is most helpful when you encounter non-accessible content.
Calmido Foundation
To protect our mission for the long-term, we are exploring a foundation structure. This ensures we keep focusing on users, not just profit.
