It does not filter any calls! *2022-10-26, version 1.5.6* What does this app do apart from 0% of nothing? Don’t down load it! Waste of time. I had robo calls coming in every 2 mins (as to why I’d try this app) NOT ONE TIME DID IT SHOW ME THE NUMBER IR DO ANYTHING! ### 3/5 — Overlaps *2022-06-23, version 1.5.6* Good app but the ads take upon to much screen space unable to hit X button to close even after 20 seconds ### 1/5 — Disappointed *2022-01-16, version 1.5.6* Just downloaded the app and I’m already disappointed! Each time i try to do anything in the app it force closes again on me. Can’t use it if it’s going to keep doing that. ### 1/5 — Doesn’t do anything *2021-11-29, version 1.5.6* I went through the setup to load and turn on features in the settings, but I’ve gotten many spam calls since installing it. I have an iPhone 6. I don’t see that this app works at all on my phone. I’ve been blocking the numbers using my phone’s blocking capability. I’d like to block spam before it even rings my phone. This app won’t do that. The app never shows who is calling. Never blocks a call. The caller list on the app is empty. Not useful at all. ### 3/5 — Keeps crashing! *2021-10-07, version 1.5.6* The app keeps crashing when I tap on a number after looking it up! Please fix this! ### 5/5 — Call time saver. *2020-09-13, version 1.5.6* This is a superb application. It takes the guesswork out of what calls I should answer as being a legit, spam or scam call. THANKS! ### 3/5 — Was fine but now it identifies none *2020-02-12, version 1.5.6* When I downloaded the app, I was pleased, as it allowed me to find out if calls were from real people. However, not long after I started using it, it simply stopped finding information. I finally just offloaded the app after months of trying to ID numbers but only getting ads for other, similar services. ### 1/5 — Not working on iPhone 6s Plus *2019-10-03, version 1.5.6* Installed and will not block any spam, I receive a lot of spam calls, 9 today that was not blocked and I tried to do an update to the database and would not connect. This may be a great program but for me it is useless ### 1/5 — Doesn’t do anything it claims to do. *2019-04-08, version 1.5.6* All it does is occupy space on my phone. Phone rings, nothing other than the usual caller ID. Number searches don't seem to work either. Poor instructions/documentation typical of most apps, No response from developer to request for help. ### 1/5 — FREE TO DOWNLOAD... *2019-03-26, version 1.5.6* ...gateway to PAY SPOKEO TO USE. THIS IS REALLY ABOUT SPOKEO MONTHLY MEMBERSHIP. I’m sick of the “FREE” teaser apps out there. Be honest about it in your description. Offer your app for a one-time selling price for unlimited use, if you really want my attention. I don’t do monthly memberships to get nickel and dimed to death. ## Frequently asked questions about Showcaller ### What does Showcaller do?
