ixabaCalc

It's a new GBF calculator app with improved UI and database, etc. It has become.
As for the calculation formula, I referred to motocal, so I used motocal to calculate the damage I think you can use this app to make a light calculation before making a calculation.

The features of this application are as follows

You can easily switch between the weapons you are equipped with.
Adding a weapon is easy, and choosing a second or third skill is a breeze!
The damage calculation also takes into account the enemy's defense value and damage limit!
Critical damage is easy to understand, as it also shows the rate of occurrence and the magnification at the time of occurrence!
You can also set up buffs, debuffs and jobs in the profile field.

There is a function to update the weapon list without updating the app, and more features are available. See this blog post.

I made this as a hobby, so there are weapons and skills that are not supported. Also, since it is a free application, it includes advertisements. Please note that we do not have any information on this.
