kalleo will empower you to take your mobile number back from the constant spam and robocall abuse.

kalleo will block robocalls, spam and phishing scheme and will fully identify incoming phone calls.

kalleo only takes a minute to set up for a lifetime of uninterruption and transparency.

Simply “Deny to Identify” and take back your phone experience.

Key Features:

Call Forwarding
By forwarding your phone number, kalleo is able to function as a service and work outside the limits of your phone while maintaining your privacy. This enables better identification, call blocking, and the ability to choose when you want to be contacted. Another benefit of the call forwarding approach is that it works for all carriers.

Blocks Outright
Blocks known spam callers and scammers from getting through instead of just sending them to voicemail.

Fully identifies incoming, unknown callers for complete transparency.

Unlimited Voicemail
No more full mailboxes. Never miss an important voicemail again. All voicemails are text to you so you can share anytime.

Community Based
Flag new spam callers and contribute to a spam-free community. Every time you help kalleo identify new spam callers, the entire community benefits.

Security and Privacy
Security and privacy is a top priority. kalleo will never sell users’ information for profit or use that information for anything other than what’s intended. Also, every incoming call is encrypted, keeping your calls private.

When you see an unidentified call, simply deny the call and this is how it works:

Identified Caller
- An incoming call is connected with the identity of the caller

Unidentified Caller
- An incoming call is intercepted and the caller hears a message that they are unidentified
- The caller is then sent to voicemail
- You receive a notification that an unidentified caller was blocked
- You receive a notification with the voicemail

Known Spam, Robo Call, or Phishing
- An incoming call is blocked outright
- Caller hears a message that they were identified as spam
- You receive a notification that a spam call was blocked

Stay away

I installed this a month ago. It may have helped to stop toll free spam calls, but nowadays spammers clone numbers or use a commercial
Phone number and Kalleo can’t stop those.

Kalleo ALSO uses a call forwarding procedure for voicemails so you no longer receive voicemails on your phone with your own carrier. Instructions to deactivate do NOT work - to stop the voicemail call forwarding you go to their web site and call a number dependent upon your carrier to deactivate. I can say this does not work - or at least hasn’t worked with my carrier Sprint - thus I’m in a quandary of trying to get out of this useless app and get my VM back.

Kalleo review

After downloading the Kalleo app literally stopped all spam calls. I used to get no less than 6 per day. Since Kalleo I now know who is calling me through the call identifier, but also eliminates un wanted calls. I will be happy as the app continues to develop into more phone services syncing with the app to make it more fluid

I recommend this app!

No more guessing!

This is one of the most useful apps I have downloaded lately. I love that I don’t have to guess as to who might be calling me, & gamble on answering a robo call!! Glad to get some control on my phone Back!
