Advertising has been completely removed from EzFormulaPro.

We are disappointed that Apple refused our approach for using advertising particulary because it had been clearly explained in the previous version which was accepted.

However, we knew that this is not normal use of advertising by asking the user to click on the ad. We want to mention that the user has to spend some time (5 seconds) on an ad in order to get free usage with advertising. We believe it is a fair compromise between publisher and app user. Even so, we decided to add in the refused version 1.4.0 a five minutes delay between every request of free usage.

But now we can’t sell usage and present to the user at the same time advertising. So we decided to remove advertising completely from EzFormulaPro. To compensate we will give free EzFormulaPro money to every new user.

We are sorry for any inconvenient.

Here are what’s coming next in the new version 1.2.0 :

  1. Now for those who wants to pay only for the solutions they are a lot cheaper :
    • Up to 200 solutions for just 0.99$ and,
    • up to 500 solutions for 1.99$.

    To differentiate formulas value, we introduce EzFormulaPro money ξ ( Xi ). This money can be used such as it is in a game but here to get a solution. Presently, the cost for a solution varies from 1 ξ to 2 ξ.

  2. Two new types of formulas have been added ( Finance, Health )
    • All in all, this represents 16 new formulas where a solution can be found for every parameter.
  3. Now you can select which types of formulas you want to display.
  4. For those less familiar with notation E (1.00E2 for example), now there is a standard decimal notation (will be : 100.00).
  5. New user modes have been introduced to simplify the user interface (can be used in expert mode or not).

Important: when you click the “Solve” button and there is no solution found, the bank of solutions will not be charged as it is shown in the following video clip.
