Please use online version

This app does not work but boy do I tell you online is amazing. Search up instant checkmate in safari chrome whatever web browser you use and it works amazing. And no it’s still not free but that’s a good price to pay for such good results. (Did you catch that. Good price to pay. Get it haha)

Ehh (privacy problems)

I feel like this app is pretty good but it can give out false information or no info on certain people. One thing that I do find weird about it is that it’s accessible for ALL people and gives your FULL address (most of the time) and your number, and when you were first and last seen. This would be good if your looking for information on people but the fact that anyone (including sex offenders and robbers) can see were you live and in what state, town, street and address can be a bit concerning because of the fact that they don’t get your permission on what they put on there site about you. Overall it’s pretty good but there are some major concerns involving privacy.

Great Screening Tool...but you still have to filter!

ICM (instant check mate) gives you a treasure trove of information. Fairly easy to read and fairly current. That said, you still have to make sure you are looking at the right person, and beware that ‘associates’ may just be people that lived at the same apartment complex (and who knows their neighbors, really?!). Real estate info is too voluminous, and should be summarized. Finally...way too much focus on nearby ‘sex offenders’. I don’t think all sex offenders like to live near each other...or do they?

Thank you for the positive review and high rating! We appreciate you taking the time to leave your feedback. Please let us know if there's a way we could improve your experience. Sincerely, Instant Checkmate Support
