Hello everybody This is my very first creation for Android. 7Calc is a calculator but also a currency converter and a measurement unit converter. You can set it up in Spanish and English (so far). Well, I know it's not the most original idea, but I thougth it was a good Project as a beginning. I would like to thank Erel and all the people who share their knowloedge to help people like me. You can download 7Cal from https://play.google.com/store/apps/details?id=b4a.calc Feedback welcome.
