Unfortunately the mobile app has limited functionalities compared to the desktop one. These limitations are very conveniently omitted on the website, were it is mentioned instead that the trial version has limited functions; sadly once you register for a paid license, you will find out that the app still has limited functionality compared to what advertised on the website. Customer support is extremely rude and shady. If you get the paid mobile version, do not expect advanced gas planning

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!
