I don't see the Problems. It is pay once not anual. I have been using it for 15 plus years. if I change phone I email and get a new code. I even changed email accounts and got a new code. I read these 1 star reviews and its either BS or just dumb people struggeling to read. Email the contact and tell them the issue and you will get a responce fairly quick usually less than 24h. So I dont know. works awesome and great support I get all my students on it too.

Be careful. I paid their $60 app fee and a year later, time to pay again! Does not maintain your account so continue paying. The interface is below average, minimal at best. They suggest you can use the same app on a laptop... time to pay again. Really poor effort guys!

After paying $45 to register the application, it regularly decides—for no discernible reason—that my phone (a 100% stock, unrooted device) is now unregistered. The developer has been unhelpful, at best. Don't waste your money.
