User Reviews

Overall, reviews show a mix of positives and drawbacks. Many users praise the app for easy setup and effective spam blocking that reduces unwanted calls, offering peace of mind. However, several users note downsides: it can block legitimate calls from unknown numbers, may lead to worse spam for some, and it requests extensive permissions which raises privacy concerns. Not all experiences are the same, and some users also mention intrusive ads and price considerations. The app works well for some but isn’t universally flexible or free.
Pros
  • Easy to use with a quick setup
  • Effective spam blocking that stops unwanted calls
  • Provides peace of mind by giving quick visibility and control
Cons
  • Blocks calls from numbers not in your contacts (inflexible for new callers)
  • Some users report worse spam after installing (not solving or increasing spam)
  • Requires many permissions / privacy concerns

was going to try to add to my words but ran out of space just mentioned this issue to a neighbor who works in development and security for his company he said it sounds like either my phone was hacked or y'all were. I'm kind of thinking maybe I was because had been getting a lot of spam messages and calls. Thank you too have a good day!
