Robocalls have become an incessant nuisance plaguing phone owners today. In 2022 alone, Americans received over 50 billion robocalls according to YouMail’s Robocall Index. Fortunately, apps like YouMail and Truecaller offer powerful call blocking capabilities to help combat this problem.

In this in-depth comparison, we’ll evaluate the strengths and weaknesses of these two leading robocall blocking solutions to help you choose the best app for your needs in 2024.

Key Features Compared

Call Blocking

Both YouMail and Truecaller automatically detect and block known spam numbers using constantly updated databases. However, YouMail has a slight edge with its “Audio Fingerprinting” technology that analyzes and flags new robocall messages in real-time. Truecaller relies more heavily on its community-reported spam list.

YouMail provides more flexibility to personalize your call blocking. You can create custom block/allow lists, set up auto-reply messages, and enable different behaviors based on your current status (busy, driving, etc). Truecaller allows you to block by number or name but doesn’t offer as much control.

YouMail states it only uses your data to provide its services and doesn’t sell it to third parties. However, it does share some data with business partners and uses it for targeted ads.

Truecaller collects more extensive information about you and your contacts, including social media data. It has been criticized for a lack of transparency around data collection in the past. In 2019, it was caught signing up users for UPI accounts without clear consent.
