My 8 year old must have left a bad review

I got an email concerning a bad review for this app in which I have never used. It seems my 8 year old not only downloaded this app but left a bad review. His review “Do not get it, it dose not work the same people call me.” I’ll ask him in the morning but I’m sure it’s him because of his spelling of “does.” His intentions were good as I do get a lot of spam calls. Maybe I’ll try the app out anyway. I changed the review to 5 stars as I can’t figure out how to delete the review.

Bait & Switch

Just another Bait and Switch app
“FREE”!! to d/l yet is nothing more to d/l something to use up more space
😂 $13/subscription to get a working app
🤣 How many apps have I seen who do the same B/S
I have one that is ok, & IT IS “FREE” no subscription to have to do to use the app
It even reminds you that you need to update it so it can help keep you safe from calls
The other app doesn’t get them all, but when I
1st d/l’d it I went from 8 calls to 0
You can add numbers to be blocked
This one I got real uneasy when I read the terms & policy
I don’t want someone tracking my calls
That is 🐃 💩 saying it is to id you and we use the information to help make the app better 🤣
Man if you can read between the lines on that you need to be USED
Have no intention of even clicking agree with the T&P cause it’s not safe
I stick to my app I have not this one
This is like the saying goes “Buyer Be Ware” !!!

Developer Response ,

Thank you for this feedback, I will pass it along to our Team. Privacy is our top concern, for the 12.99 membership fee you have access to a complete security bundle. You can find out more information here Regarding "tracking," again, privacy is our top concern. Any call blocker (free or paid) is going to need to take the incoming number and compare it to a known spam callers list in order to work. Our Privacy and Terms are very clear we do not "track" you. I would be more worried about how the free service is making money. I hope this helps, if not please reach out to us. We are here to help.

Breath of fresh air

I’ve been a loyal user of Hotspot Shield for many years so I was happy to hear when they released Robo Shield. I’ve been using it for a few weeks now and it does seem to fix this huge problem of getting spam calls. I used to get at least 5 of these a day and now I don’t get any at all.
