Iphone Android Blackberry simple data application

Hi, We need a simple application that collect data and put it into the calendar. We have a cardio frequency that records pulses data. It sends them by bluetooth. We need an application that receive theses data and listed them. The data have 3 values: date, time and pulses. We also want that the application send the data into the official calendar each pulses to the right day & time. For example, under the calendar, you can find: 7:03pm 122bpm (beats per minute) Finally, the application can generate an Excel file with all the data list in 3 columns. This file can be linked to mail to be sent to anyone. We are open to any recommandation, advices. We want an experimented developer, so please talk about your last projects and your experiences. Best regards, Dan.
