Some Cool Features But Too Invasive! I'm a business owner and I need to text a lot. I also drive and use my maps a lot. While the app does have some cool features, I can't handle having annoying messages that cover 3/4 of the screen pop up and cover whatever I'm working on. Even when they are messages that I want, I don't want them to pop up over what I'm already doing. I gave it a good solid couple of months to try it out, but I just couldn't tolerate it. I'm uninstalling the app.
This is a well-made app that is well designed and is user friendly. I recommend paying for the premium, as itโs very useful.
Love this app. Super helpful for identifying unknown numbers quickly and keeping spam away. Smooth, accurate, and really improves the calling experience.
CallApp makes managing calls so easy. Great caller ID, smooth design, and excellent spam blocking.Highly recommended!
before I downloaded CallApp I was getting an average of 20+ spam calls per day. The first day after I had downloaded the app, I was so satisfied I only got 2-3 calls. However since then the calls have steadily increased to almost the same number they were before, and the app sometimes does not allow me to see who is calling while the phone is ringing, causing me to miss several calls each day. Overall I am not satisfied with the app and am looking to replace app with another call screening app.
CallApp is one of the best apps on the market. It is very simple to use and identifies who is calling provided that the caller's name is in your contacts. Otherwise, it displays phone numbers and the location of callers who are not in your contacts, helping you with deciding to block the number. The reason why I gave it a 4 star review is because I wish that they would include voicemail. Otherwise, it is a great app!
