I am a computer Science Engineer that have programmed an App for fun while learning, and wish it can be useful for many people.
My first published App at Google Play is named "Stock Alert Formula" (English), "Alertas de Bolsa" (Spanish), "Avvisi di Borsa" (Italian)" "Alertes boursières" (French)" and "Alertes de Borsa" (Catalan).
