I have tried many tracing methods and paid for apps. But this app gives accurate information. I tested it on my number. In fact, it is a little scary how accurate the information is. The app reveals information about myself that does not appear on Google, Microsoft, and many other platforms. past.

Subscription issue, I already subscribed to this app, but it is always when I am searching, asking me to subscribe. When I click on subscribe, they return me to google, and google said that i already subscribed on this service.

The app is not working, I have deleted it and reinstalled it more than 4 times already but still I can't access anything, and thank you for sending me an email, but your team never resolved this issue, may I request a refund as I'm not benefiting from the app at all ? ××××An update regarding your reply, I have received an email from you stating that you will share my issue with your team and revert back to me, that was more than 9 days ago, will you ever solve this issue or I shouldn't expect.

    I just lost over $30. I barely found any new information. I could have just asked a cop friend for it. A monthly subscription would have saved me the hassle. A one-time payment for a search would have been even better. I'm really frustrated.

    I recently uninstalled the app because I didn't have credit or debit cards for payment. I recommended it to my sister in Europe, and she's thrilled to connect with her school friends through it. Such a useful app for staying in touch with many friends and business clients. I give it 9 stars for the developers. Much love and peace!

    A few months back, everything was great. Now, it shows incorrect results and mismatches names with numbers. Really disappointing. It feels like a waste of money. I had bought a one-month membership and considered switching to an annual plan. Now, that doesn’t seem like a good idea anymore.

    The experience was disappointing. At first, the description excited me. I downloaded the app and started exploring. None of my searches returned accurate results. I wondered if it was because I'm Nigerian. The frustration grew when I couldn't find any Nigerian numbers or email addresses, even with the advanced search option. I wanted to provide feedback but found no way to do that in the app.

    The app is giving me a lot of trouble. I deleted it and reinstalled it four times, but nothing works. I can’t access anything. I appreciate the email you sent, but the problem remains unresolved. I want to request a refund since the app isn’t useful for me at all. About your previous reply, I got an email saying you’d share my issue with the team and get back to me. That was over nine days ago. I wonder if this issue will ever be resolved or if I should give up hope.

    I got a one-year subscription, then had to format my phone and reinstall everything. My subscription is activated on my Google account, but it doesn’t show up in the app. Reaching out for help didn't work either. Honestly, they deserve one star at best.

    That sounds really frustrating! It must be annoying having all your numbers end up in the same spot. At least it gets the country right, but that's only because of the dialing code. Feels like a big letdown and a waste of time and data! It's disappointing when something doesn't live up to what it promised.

    A person texted me. The app sent a link to my phone. I clicked it to reply. Now, whenever someone calls me, this annoying AI assistant message plays. I can't get rid of it. Frustrating!
