A fraud, owner is a scammer.
Like many others, we have been denied our account. We paid for a lifetime license, but a few months later we can no longer use the service. When you contact Felix (the owner), he claims not to know what's going on, and informs us that we have to subscribe to a recurring yearly premium support... except that he knows perfectly well what's going on. A total hypocrite as on top of being dishonest.
Long term user. My account was disabled. I asked the owner in support why my account was disabled, he plays like he doesn't know the reason and that he will have support fix the problem. 3 weeks later I see this happened to others. I asked if they will fix my account and the owner tells me they will email me, his way of saying don't bug us anymore. Paid user and they permanently disabled my account. So many better options to waste anymore time with these people.
A very great beginner friendly tool. Im new to SEO and bought Ranktracker LTD tonsupport them. And so far i like it. Its even getting better with time. In near future inthink, ranktracker will playna huge role.
I got Rank Tracker on App Sumo over a year ago and have since bought LTDs for a number of similar products such as Labrika, True Ranker, Dino Rank and a couple more. RT is hands-down the best of these. It may not yet be as versatile as the major players but it is on its way there. A lot has improved. There are a couple of minor quibbles but it has decent results and has proved very valuable to me. I am offering SEO services to smaller local businesses and RT is helping at keeping my prices attainable. It has better competitor comparison than the other tools, is the only one doing Bing as well and is simpler to navigate.
Felix is a developer-turned-scammer! He disabled the free-for-life AppSumo accounts of those who trusted and gave him money when he was desperate to grow the business. Thanks for showing yourself; now we (users and investors) know who you are.
