Voilà

Great product, Ive installed it to my IPad. Even the free version is far beyond your expectations. Ive e-mailed a bug and an update issued to fix it just two days after. The producers are so responsive to answer the needs. Ive read some criticism at the site that the calculation is not perfect but Ive not faced such a problem yet. But if I do so no doubt that the producers would fix it immediately.
