Are you tired of developing mediocre apps day after day?

Would you like to be a part of a great success story in iPhone / iPad development?

Highly skilled iPhone / iPad developer is required to update and redesign our successful app.

This app is called "Spreadsheet touch".

This app is currently in Top 10 in UK, Australia, Top 20 in India, Canada, Japan, and Top 22 in US.

(To find out this app, please search "Spreadsheet" in App Store. You will see it.)

(Some other apps are also listed here: [url removed, login to view])

I need someone who can take this app to the next level.

This person will be (almost) genius, highly skilled in mathematics, and hopefully have some experiences developing spreadsheet applications or something similar.

Currently, we cannot implement certain features such as "Merge cells" because of the limitation of the basic structure of this app.

I would like to redesign the basic structure of this app, migrating all the existing features, and add some other functionalities into it.

Please be sure that handling these tasks will be complex.

Because of this, I need an "iOS architect" who can build remarkable apps.

The reward will be ongoing development opportunities with top dollars.

Before redesigning everything, I would like to ask you to add the following features into this app;

- Set up special keyboard (Adding 30 keys into form assistant area above the standard keyboard)

- Add "Font" button to change font size (9 sizes in total) and font style (8 styles)

- Navigation bar and Status bar will be invisible when using the keyboard

* I've already prepared a detailed documentation to share with you after signing NDA.

That's it for this current project;

After successfully completing this small project, we will move on to the bigger project, that is to redesign the basic structure of this app and add more features such as "Copy & Paste Rows and Columns".

I am looking forward to hearing from "the best" developer in this field.

Thank you,
