    Very happy with Robokiller

    I’ve been using Robokiller for about a year, or a little over a year, and I’m very impressed by it. Before I got it, I was getting spam calls and texts left and right, and it was really annoying. I found Robokiller in the store and did the free trial. I set up everything the app needed so it could do its purpose. To my amazement, during the free trial, my phone was quiet from spammers, and it was a relief. Sure, there were times it didn’t work, but that’s because my phone kept forgetting that I have Robokiller installed, so I had to go to my phone settings to remind it. I know it works because I’ve had people call me and tell me that it would send them to the voicemail I setup with Robokiller. Without me telling them about it. Is it pricey? Yeah, sure, but is it worth it? Absolutely. If you own a business that’s a different story, and hopefully you’re using a company phone. This is more for your personal day-to-day phone. I do, however, wish that Robokiller can separate voicemails from known numbers to my phone instead of sending them to Robokiller. If someone I love passes away and leaves a voicemail, once I uninstall the app, that voicemail is gone. So find a way to separate them, known number voicemails to phone and spam voicemails to Robokiller. Other than that Robokiller is great, and I can’t live without it. Until developers somehow manage to jeopardize it, then it’s bye-bye.

    So great!

    After being fed up with spoofing, spamming, and scamming calls day after day not knowing who it was, I was in fear that the next call would steal my identity or try to scam me. I heard about this app so I downloaded RoboKiller to see if it could help, i didn’t know it was so hilarious too, I mean roflmao funny, it had the scammer believing they had called Area 51, now I don’t have to deal with any annoying call that isn’t a bill, no more scammers, telemarketing, and unwanted calls from people you don’t want calling, you can also go back and remove a number if you need to, I would recommend this app for anyone, I don’t have a lot of debt collectors calling but if your overwhelmed by these calls and fallen on hard times I would recommend this app, even some debt collectors can be aggressive without ever hearing your story calling back to back, they have resulted to threats at times, then on top of it getting calls from scammers who use tactics like threatening to have you thrown in jail, bots, and many other annoying calls, this app is worth it, most of the numbers are in their database, but if not you can add them with a description to help others to decide whether to take a call or not, this app can help protect you against unwanted calls, lower chances of identity theft, from being scammed for money, or being harassed by any caller, don’t wait download RoboKiller, they are offering a trail period so you have a chance to test the product, it’s worth it, this is my opinion- Z-Man

    Great app, a few simple fixes could make it greater

    My phone got to the point where I got 15-20 calls per day of spam, scam and spoofing. I don’t need to go into detail of what they were because by now we all know them. THIS APP WORKS!!! In two weeks I’ve gotten only 3 calls that have come through. One of them was marked “unknown” and there’s nothing any app can do about that. It says it blocks a few a day but I’m sure it’s much more since many spams just hang up and don't interact with the bot. There are however two issues. The first is the default bot message. It says you are using robocall and invites the caller to leave a message if they choose. It also says the message may not be heard. First, the caller ca talk and be recorded while the bot is talking. That makes no sense. I wish it could be a customized voicemail so in those rare occasions were a legit call gets through someone can leave a real message and doesn’t need to know they’re talking to an app. This would be huge especially for someone applying to jobs if they were to miss a call from a hiring company. Also, I missed two calls from capital one and Amex. Since much of this is crowdsourced I’m wondering if people are reporting legitimate phone numbers as spam because those numbers are calling them for legitimately unpaid bills. It’s wrong for people to report numbers as spam because they want to avoid valid calls.
