BellsClock

Version 2 update:
* Navigation among pages is done by the hamburger menu.
* The screen color can be modified and personalized.
* Individual bell schedules can be exported to Comma Separated Value (CSV) text format.

Details:
You can customize a bell schedule by adding or deleting class periods, modifying their start and end times, adding or deleting whole schedules, and modifying the names of the periods.

School bell schedules can be imported from a Comma Separated Values text file located on the device or, for school-wide distribution of a set of schedules, from a Web site.

The CSV file format is simple:
- Quotation marks are optional.
- A schedule record precedes the set of period records.
- Period record format is
periodname,start HH:MM,end HH:MM HH can be 24 hour or 12 hour; simply add AM or PM for 12 hour times.

# Next line is a schedule name (no colon or comma)
