Finally, an app that doesn't want excess access and a bloated subscription fee. It's a 1 time $2 upgrade and does all I want it to, which is whitelist my contacts and a small handful of area codes while blocking everything else.

I'm loving this app! Been getting tons of spam calls from Indiana, and I can block all the area codes, so they won't bother me!

Does exactly as advertised ! No ads or annoyances. Looked at other call blockers and those were subscription based and expensive. I am happy with this product and my ability to keep scammers out of my hair ! P.S. Thank you for coding this effective app !!!!

Does not work at all...as simple as 18 prefix block does not work.

10 calls blocked and then immediately your pay walled permanently. There are completely free apps that do this.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
