Cons Only available on certain Android devices, not as many customization options as some other phone apps

Comments and Reviews from users:

Hans: “Just ok, barely. Call screening no longer works on the Motorola Razr Plus 2023 yet it works on older Motorola phones. The call history is a hit or miss, sometimes you can see it, sometimes it can go back only a month, it's random and not really reliable. Why Google doesn't put a version number right in the app so you know which one you are using is strange. Most phones ship with a version of Google dialer but that is often replaced during app upgrades. The problem is that both apps co-exist.” – 2/5 in Play Store

Ashley Arndt: “Works great. Easy to use and navigate. The one thing I don't like is not being able to see the transcript of a screened call. It's supposed to be saved, but nothing shows, & it's basically an empty document that says who called, but no conversation. I also would love it if I could screen/record outgoing calls. Or at least let me use a separate recording app, to record outgoing calls, for my security. Companies record us all the time during outgoing calls, so we should be able to do the same.” – 3/5 in Play Store

Comments and Reviews from users:

Stealth !!!!: “Great app that combines three different google apps (phone, messages, and contacts) into one convenient app. Ads aren't very intrusive and outside of that the only small complaint I have, and hopefully a very simple quick fix, is that of you put something into the clipboard then whenever you open up the sms/text section of the app it immediately pulls up the number pad with this clipboard and number ready to be pasted.” – 5/5 in Play Store

Talmar: “Been using this app since 2015 and i love it. I see complaints about the accesses it requests. It is meant to be used as a replacement for your regular phone app, so it needs access to contacts, sms messages and call history as well as being the primary phone app in order to be used as default phone app. In 9 years it has yet to be a security issue for me.” – 5/5 in Play Store

Yasser Flávio Rabello: “The adds are annoying. The interface looks ugly with too much information on the screen. Also those random names of people that show up in our call history should be written in a different way then the ones that we actually saved in our contact list, so we can differentiate them. Then we would know that those names may not be accurate for their numbers. Which is most of the case. I actually only like this app over the other ones because we can record the calls. This is the nicest feature on it” – 3/5 in Play Store

Cody Holt: “I'm seeing a lot of 1 star, but it seems to me most of it is user error. I have a android s10 and no real issues. I bought premium and it works fine. The recorder could use some work as it records pretty low volume even with Max settings, but it does work if set right. I've had the app for a couple months now, no complaints. Edit: the recorder has received some updates and it's working great for me. Very loud and clear. I love it.” – 5/5 in Play Store

Cynthia Garcia: “The app says I'm not a customer, which I absolutely am. Edit: Because my device is "unlocked" I'm unable to use the call filter app. Fortunately I was shown a means of editing its properties through the My Verizon app. I've updated the rating to 3 stars for the assistance I've received and will follow-up with another updated rating once I can gauge the filter's performance.” – 3/5 in Play Store

RuthAnn Roy: “This app is a huge help! It sends notifications when an incoming call is potentially spam, or just a number you have blocked. Then it allows you to choose which category that number most resembles. Ie; Spam, telemarketing, etc. If a call does come in and inaccurately marked as potential spam- you may remove it from the list. I chose not to purchase the full featured app that offers more options. The free version is very adequate for my needs. It's great maintaining Peace of Mind!🙂” – 5/5 in Play Store

Comments and Reviews from users:

Cynthia Bea: “Used this app for quite a while, it's okay, but since it requires to be the default app, it can't pull up any contacts in contact search, and always warn you, that you may be charged if you use the dial pad to make a call, and the blocked numbers appear on the call log along with my regular calls, I can't tell which number is which. I end up using another app for dialing a number, or looking up a contact, and messages. There's too much wrong, unnecessary stuff on this app for efficient access.” – 2/5 in Play Store

Donnie Chen: “There are popup ads with every call screened, and the ads are intrusive, they take up 50% of the screen. The ads also pop up out of nowhere. I would be using my phone, and out of nowhere and ad would cover my entire screen. Not 1 star because the app does block unwanted calls, but 2 stars because the app is super intrusive. You have to give them access to be your default calling app, and you have to grant them permission to everything. They have pretty much full access next to the phone maker.” – 2/5 in Play Store

Phillip Gonyea: “The call blocking feature seems to work well. I really have no issues with most of it. However, I have an issue with the VPN. First off, if you turn it off in the app itself, it doesn't actually turn it off. You actually need to do it in the phones VPN settings. No big deal, a bit inconvenient, and would knock it down to 4 stars. But this is why it's 2 stars.... the VPN turns back on.... on its own. If you have an app that requires it to be off, forget having it work correctly. Had to delete app” – 2/5 in Play Store

Sandra Harrison: “I keep getting this annoying message when I try to block a number: "We couldn't complete your request, let's try again." I will give it more stars when that annoying message goes away. I prefer the older version. I increased it to 3 stars because I have seen some improvements. Now, orn the Identity Monitoring, I have 2 alerts regarding my email0, but I could never see the alerts because it won't stop downloading. Aggravating!” – 3/5 in Play Store

A Google user: “I absolutely LOVE this app. Since installing it I have not had ONE irritating phone call. I dont know if it is any better or worse than any other app of this type. I was using the "blocked caller" feature of my phone, but they just called from different numbers. I installed the app, simply blocked all calls from numbers not in my contact list, and voiala ... no more unwanted calls! The phone doesn't even ring! It bothered me at first, but not one has left a message. Problem solved!” – 5/5 in Play Store

A Google user: “Works as listed. I use the app to only ring my phone when a saved contact calls, eliminating all telemarketers, and all non-approved calls. I wish there was an option to simply 'white-list' all contacts, but it only took me about 10 minutes to check all my hundreds of contacts to the white-list. So much for the FCC's 'Do Not Call' list! This app works, since that list fails! Thank you!!” – 5/5 in Play Store

Comments and Reviews from users:

Michael Creese: “Disappointed! I really thought with all the news releases leading up to this app's release that this was supposed to be free. The free version has very few features. Instead you have to pay to upgrade. I don't get it. You can't even block numbers without paying! Well it does block fraud and it does provide caller ID. Both free. So that's good! If you want to block specific numbers on the network, or block other types of calls such as Telemarketing or Surveys, you have to pay a monthly fee.” – 2/5 in Play Store

Derrick Metras: “The app basically does what it says, and a little bit more, but there's a few catches. First off, if the "Scam Block" is on, it's only going to block the call if T-mobile has the number listed as "Scam Likely". Makes sense, but not clear to users. It's not exactly the easiest interface, either. There are premium features (which is ok) but I'm not here for those. The app has a built-in reporting tool to manually send info to the FTC/FCC (per call). It's easy to use (1-2 min), not easy to find.” – 4/5 in Play Store

Comments and Reviews from users:

A Google user: “Good app that got greedy. I loved it and recommended it to all my friends. Now it's wanting me to pay premium to get names and info. And it doesn't just ask once. It puts two pop ups on my screen after a call about going premium and on the info block of the call, it says (literally) "name" then "premium" to make sure I know that I'm not getting everything I could. It's trying very hard into shaming me into upgrading.” – 2/5 in Play Store

A Google user: “I've been using this app for years. Its always accurately and reliably identified my calls with at least a 95% accuracy both in terms of spam calls and otherwise. Before one of the more recent updates the app would identify all calls with a name for free. Now they started charging you to for that and at the same time the 95% identifying accuracy has gone down to about 80% I apps have to make money but id rather see ads than pay a monthly subscription.I would even pay a 1 time fee for this app.” – 2/5 in Play Store

Brandon Page: “Everything works great except for one thing but I'll get to that in a second. I'm on OnePlus and I miss call screening from when I had a Pixel so this is perfect. The UI is clean and simple. And the chat bots for calls pretty sure have scared a few people. The only complaint I have is my text messages never load properly and I can't view them or send them. Besides that it's great for keeping the endless spam away especially if you register with the Do not call registry for an tad extra security” – 5/5 in Play Store

A B: “This app works very well to block the avalanche of spam and scam calls which we all receive these days. However, it needs one huge change to the answer bots to deal with the way that many scam calls work. Stop using the word "Yes", or variants, in almost every answer bot script. Many scammers are explicitly trying to get a recording of the victim saying "yes" to falsely claim that you agreed with some purchase or payment program. That eliminates 95% of your bots from practical use.” – 4/5 in Play Store

Comments and Reviews from users:

Roger Schwed: “This is by far the best call blocker I have found for an Android 10 phone -- better even than the numerous paid options. And you DO NOT have to set it as your default phone/dialer app. It allows you to block all incoming calls, save for numbers in your contacts and whitelists -- and allows you to set up wildcard filters for both your blacklist and, this is much rarer in blocking apps, your whitelist (i.e., getting a return call from an organization that has multiple lines sharing the same prefix). In addition, adding to both lists is made easier by being able directly to reference the call log (sadly, only incoming and blocked at the moment, not outgoing). Blocked calls do not ring, but will give you a notification in any form that you configure it. However, the blocked calls can still leave you voicemails -- but I'm not sure that can be changed unless the app is your default Phone app. Kudos also to the developer. He's extraordinarily responsive to suggestions. I've sent him a bunch and he's already implemented a number of them. I have confidence this app will continue to develop positively. You should try it, and definitely donate if you like it!” – 5/5 in Play Store

Mike Mennino: “Wasted way too much time on other call blockers.Fiorenza's V4.2.1 Call Blocker actually does what its supposed to do... block calls --- importantly, with wild carding that works -all- the time. Great app. I keep the app's 'shield' ICON on the notification bar (via settings) to be sure it's running in the background. Rarely, if ever, does the task die. If it does, other background tasks are dead too, so it's the phone's OS that should get the blame. My phone is currently running Android 8.1. Be sure to enable all permissions when installing.” – 5/5 in Play Store

A Google user: “After using this app for almost a year now, I can still give it 5 stars! It blocks EVERY call except those in my contact list. The only issue is this. While on a call, if a call comes in and it blocks it, it hangs up on the person I'm talking too. The only way I have found around this is to turn off the blocker temporarily when I'm on the call, or turn it off before I call someone.” – 5/5 in Play Store

A Google user: “Good user interface. First thing i did -- with the app's help, was to replace the native, default Phone app with Should I Answer phone app, but the app makes it so easy to switch. The new phone app adds spam-reporting capabilities, otherwise it's the same as the original. Second thing i did-- with app's help, was enter all the Spam calls that were saved in my phone's history. Took a little time doing one-by-one, but the app makes it easy; my contribution to the database of spamming scammers.” – 5/5 in Play Store

A Google user: “The only people I talk to are people in my contacts list. I never give out my number to anyone, so the repeated calls from telemarketers were never answered. Now? 1 short ring and nothing. I love that this app picks up and hangs up on people calling. It's frustrating to them too as I'll sometimes see 3 calls in a row. I check that number and it's SPAM. I love this app! I had the old version which was hit or miss with the pick up hang up method, this version is perfect...so far.” – 5/5 in Play Store

Comments and Reviews from users:

Gary Hovey: “I haven't received a voicemail since I downloaded the app. I have been through the app extensively many times to find out why and a possible solution with no resolution. Despite my several attempts to contact the developer via message (the Only contact they offer) upon tapping the "submit" button, a box pops up and only allows me to Share W Other Devices or to other apps, such as messenger. I will Not renew membership, and I will not refer anyone to the app.” – 3/5 in Play Store

Bronxbomber4ever: “When it worked it was okay. Very few calls got through but then again, I had registered my number with the FCC and was on the no call list shortly before activating the app. Unfortunately, it disabled my visual voicemail. This is totally unacceptable and an old issue that needs to be addressed. Why isn't there a simple way to fix it? Decided to cancel. Too much work to fix their issues. I can just go back to manual blocking instead of paying to be a beta tester. They only made 5 bucks off me.” – 3/5 in Play Store

Jackie Kidwell: “This call blocker is excellent !! I don't have a lot of storage on my phone and THIS call blocker doesn't use much, I have another call blocking service I may have to get rid of as it uses a lot of megabytes, 64 !! Anyways, this service seems to be great so far and seems to do everything it claims. I would highly recommend it to anyone. Love it. 😀😀😃😃💜💜❤❤” – 5/5 in Play Store

Blake Harris: “This call blocking app has proven to be a great relief from unwanted (spam, robocalls, scam artists) calls. Every call I receive is screened and if the caller is not in my contacts list it is automatically dismissed without ringing my phone or anything, so I don't have to do anything to reject the call. And best of all, calls are not dumped into my voicemail. I am so thrilled that I discovered this app in the Google Play Store! Thank You so much!!!” – 5/5 in Play Store

Comments and Reviews from users:

A Mikk: “This might be the best thing ever but there are some functional issues. 1. Tiny text with no adjustability. 2. No way to mark numbers safe, that you allow. 3. Tapping send text just bumps unsent message to bottom. Have to hit send, twice. 4. Screen flickers when sending text. 5. Notifications for incoming are hit or miss. With the advent of sms spam at all time highs with no discernible app that blocks, there is a lot of money to be made in this space. Too bad TM missed the mark.” – 3/5 in Play Store

Marshall Perez Sr: “it does what it says! I've been receiving alot of unknown text messages from everywhere and it's blocking all of them except those from my contacts. It was very very annoying!!! The only thing that is wrong with this app is you have to switch from messaging default to TW check default when sending messages or the other way around. Thanks for the APP guys and keep up the good work 👍👍” – 4/5 in Play Store
