After the initial PRO trial period is over, Gravit Designer automatically changes to the free version, but we’ve recently introduced a paid PRO version with some professional features. You can find more information about the differences here. Please let us know if you are an existing user and you apply for special pricing.
With the PRO version, we are focusing on the needs of advanced users, but we are making sure that free users don’t get left behind and also receive constant improvements and bug fixes. Some of the new features will be exclusive to the PRO version, though.
