## What is Callblock?

Callblock is the first app that lets you stop telemarketing phone calls in iOS (https://techcrunch.com/2016/09/07/callblocks-new-ios-app-will-block-calls-from-over-2-million-telemarketers/), with the world’s biggest directory of telemarketers – now over 3,000,000 classified entries from over 100 countries!

The app identifies 86.7 percent of telemarketing calls correctly with a false-positive rate of only 1.7 percent on average.

Note: Callblock *cannot* block calls with no caller ID – this is an iOS limitation, but most telemarketers don’t block their caller IDs. The app is free to try for one month then will renew automatically using your Apple account for $1.99 monthly or $19.99 yearly afterwards – you can cancel anytime by going to your account settings in iOS or iTunes. See Callblock’s terms of use at https://callblockapp.com/terms and privacy policy at https://www.iubenda.com/privacy-policy/7907565.

You love your iPhone – except sometimes the phone part and, in particular, the telemarketers often on the other end of the line. Telemarketers make 148 million annoying, time-wasting calls per day according to consumer-group Private Citizen and do-not-call lists (where available) do not work (and weren’t even meant to for many types of telemarketers) according to governments themselves. Callblock helps prevent these calls.

The app blocks unwanted telephone calls not iMessage, SMS, or MMS messages. To enable Callblock to block calls:

1. tap the “Settings” app,
2. tap “Phone” > “Call Blocking & Identification”, then
3. toggle the “Callblock” switch on.

To unblock calls, go to the “Callblock” app. To add, remove, or reclassify a missing or misclassified caller, tap the “Add caller” button.

Enabling Callblock or making changes in the app may require up to a minute to take effect.

### 1/5 — DO NOT BUY. SOES NOT WORK ON IOS 14

*2020-10-15, version 1.8.0*

It doesn’t work & the author doesn’t respond to contact attempts.

### 2/5 — False Advertising

*2020-09-17, version 1.8.0*

It states this has a free trial for a month & will charge your $19.99 a year or monthly & upon downloading it I was charged immediately after I picked which subscription & free trial. States it will charge again for the same amount next month even with the year subscription. PLEASE fix this!!!

### 1/5 — I want to cancel

*2020-06-15, version 1.8.0*

I want to cancel this now give me a phone number to talk to some about this please
Rebecca Scoles 614-216-8085

### 1/5 — Misleading app

*2020-06-13, version 1.8.0*

Lists as in-app purchases, but in reality no feature is available without a paid subscription.

### 1/5 — Nothing in app is free

*2019-12-14, version 1.8.0*

This app appears to be free but has no free functionality, as soon as it opens they require a paid monthly sub

### 5/5 — Exactly what I needed

*2019-11-02, version 1.8.0*

I get tons of  “ scam only” or prerecorded calls. This has worked perfectly for me! I can shut them off and not get overwhelmed by unwanted calls. I highly recommend .

### 5/5 — Okay on boarding , but works as advertised

*2019-07-04, version 1.6.0*

The onboarding was difficult, but getting past the subscription signup it worked as expected. Blocks unwanted calls similar to the Adblock model.

### 1/5 — It says loading but it doesn’t work

*2019-06-24, version 1.6.0*

It won’t stop loading to work so I guess it doesn’t work

### 4/5 — It works

*2019-06-16, version 1.6.0*

Call block works for those 800 numbers. There is a mini subscription fee so it doesn’t damage your wallet. In order to have the app function though, you must subscribe before you can mess around with it. No worries though since you get a free trial and can cancel anytime.

### 1/5 — Nope

*2019-05-04, version 1.6.0*

Does not work! I feel like I’ve received even more unwanted calls since I purchased this app.

## Frequently asked questions about Callblock

### How does the app block calls?

The app identifies telemarketing calls using a large directory of classified entries. To enable blocking, you need to go to your iPhone's Settings, tap 'Phone' > 'Call Blocking & Identification', and then toggle the 'Callblock' switch on. Changes may take up to a minute to take effect.

Yes, you can manage the caller list within the app. If you encounter a missing or misclassified caller, you can tap the 'Add caller' button to add, remove, or reclassify them, helping to improve the app's accuracy for your specific needs.
