I'm using free account ,so,I know that I can create only one project.
However ,I think I can create unlimited pages.Is that a mistake ?
The following message was displayed.
Adding more screens is not permitted by your subscription. Upgrade to Pro to remove the limit.
The Free plans allows to create 1 app with 3 pages: http://tiggzi.com/pricing
Thank you for your kindness.
After recent maintenance , some changes take place.
I can't create a new screen in a free account.
I can't create the third product in a standard account.
I am going to see the state of affairs for some hours,
because I have to use tiggzi on bussiness. 
How many pages do you already have?
As a free account user , I have created one project which has 68 pages.
As a free account user , I have created two projects which have 30 pages.
There was a bug in how pages were counted, it's now fixed.
Thank you very much .
