The client's need was to continuously iterate with the software in development to check the correctness of the final results and to quickly implement improvements and additions, always with short development times.
The customer provided a model including all of the formulas in Excel: weLaika studied it and built a dynamic infrastructure that automatically updates, domino-style, upon data changes.
The graphics was provided by the customer: weLaika converted everything in html/css taking advantage of the full potentiality of the iOS platform, and at the same time offering a completely custom interface, in Retina quality, and quickly.
The native wrapper, besides allowing to show the results, allows generating the PDF reports natively, without using external web-services, completely offline.
The PDF report is a ready-to-print version of the previously calculated results and includes the graphics, keeping the style required by the client.
