About

iWapp

Features
Read full description

L'applicazione iWapp gestisce la tracciabilità dei propri collaboratori fuori azienda (siano essi tecnici o agenti) e la rilevazione delle ore di produzione effettuate nei diversi reparti interni alla stessa. Inoltre iWapp permette di gestire i rapportini di cantiere e di commessa, le richieste di intervento e la gestione degli interventi di manutenzione. iWapp fa parte parte di una collana di app sviluppate dalla Modi Nuovi per la gestione aziendale e direzionale mobile. I collaboratori fuori azienda potranno inviare i dati relativi alla propria posizione al server aziendale per permettere una più efficiente gestione logistica degli interventi nel territorio: utilizzando l'apposita app 'Leader Watch' i responsabili degli interventi potranno visualizzare sul proprio telefono o in modo ancora più personale nel proprio Apple Watch la gestione degli interventi in real-time.
