Call Insider vs YouMail

Call Insider is a free caller-identification service available on Android and the web. It helps people assess unknown phone numbers by showing ratings during calls or in a pop-up. The mobile app uses a database with more than 300 million identified numbers, drawing data from more than 100 websites. A downloadable database covering more than 100 countries supports lookups without an internet connection. Users can rate numbers, read other users’ ratings, see yearly interest in a number, and sometimes view a landline location. The service is intended for calls such as telemarketing, surveys, courier contacts, and office calls. Free registration provides fewer ads, editable rating history, reply notifications, more daily comments, and easier reporting of harmful comments. Call blocking for potentially harmful and unsaved numbers is described as in development. The service was created in the Czech Republic in 2011.

YouMail combines call protection, privacy tools, and visual voicemail for Android, iOS, and the web. It is intended to block robocalls and scammers and help keep a phone number private. Visual voicemail transcribes messages to text and is accessible on mobile and desktop. The Free plan costs nothing and includes 50 cloud messages, 100 voicemail-to-text transcriptions per month, and unlimited known-spammer blocking. Paid personal plans include unlimited call screening; the Free plan does not list that feature. For business use, Complete and Ultimate list virtual numbers and tools such as auto attendant, extensions, conference call recording, and business messaging. YouMail also lists voicemail notifications or transfers to Slack, Asana, Dropbox, Google Drive, and Trello. The company says it encrypts data at rest and in transit and describes vulnerability scans, code reviews, and third-party security audits and penetration tests in its development process. It works with major carriers including AT&T, T-Mobile, Verizon, Ting, and Mint.
